BPM Double Delay
Overview of properties

DirectX BPM Double Delay Plug-In belongs to the set of plug-ins called Simple Audio Plug-In Pack I supplied by DSound.

The same as all the other plug-ins of the company DSound, this plug-in has a high-quality graphic user interface and is the first plug-in that can identify whether it is being used for processing a mono or a stereo signal, and change accordingly its graphic interface and thus meet  user demands with respect to control simplicity and clarity.

This plug-in provides for setting up all the control elements independently for the left and for the right channel when a stereo signal is processed. For all effects and parameters this will yield an excellent stereo impression.

Algorithm:

   The BPM Double Delay Plug-In is a delay formed by two delay lines marked A and B, which are independent of each other. Thus a stereo signal can be created from the mono signal. The output format is set in the right mouse button menu. A change in the format of the processed signal must be supported by the host application. If the host application does not support the mono -> stereo change of the format of the signal processed, the plug-in cannot be connected to the mono track. If the plug-in is connected to the stereo track, the signal output format cannot be changed and the output format is stereo.

   The BPM Double Delay Plug-In will allow you to set the delay quickly and intuitively in the tempo of your composition. It is sufficient to set in the Tempo edit box the tempo of your composition in BPM (Beats Per Minute), then also to set the time (3/4 or 4/4) by means of the Bar control element, and in the Note Selector section to press the button which corresponds to your required rhythmic repetition of the delay (e.g. setting the crotchet note means that the wet signal will be repeated four times during one 4/4 bar). This will yield a delay in the rhythm of your composition. The length of the decay of delay can be set by means of the Decay parameter, independently for both delay lines A and B.

   When setting the stereo output format the signal from delay lines A and B can be placed into the stereo base by means of the Pan Wet control element. The resulting signal of the plug-in is given by the sum of the direct Dry signal and the Wet signal.

   To have a clear idea of what you are setting up, all parameters are shown in real time on a 3D echogram, which enables you to check graphically the delay setting.

BPM Double Delay
Description of the presets supplied

Preset description:

•	S 1/4 - delay with maximum stereo base in 90 BPM tempo, repeated at crotchet note intervals.

•	S 1/8 - delay with maximum stereo base in 90 BPM tempo, repeated at quaver note intervals.

•	S 1/16 - delay with maximum stereo base in 90 BPM tempo, repeated at semiquaver note intervals.

•	S 1/32 (2t) - delay with maximum stereo base in 90 BPM tempo, repeated at demisemiquaver note intervals, which is achieved by setting twice the BPM delay as compared with the real BPM of the composition.

•	S 1Bar 3/4 - delay with maximum stereo base in 90 BPM tempo, repeated at intervals of one 3/4 bar.

•	S 2Bar 4/4 (1/2t) - delay with maximum stereo base in 90 BPM tempo, repeated at intervals of two 4/4 bars, which is achieved by setting half the BPM delay as compared with the real BPM of the composition.

•	S 1/4 Tri. - delay with maximum stereo base in 90 BPM tempo, repeated at crotchet triplets intervals.

•	M 1/8 Tri. Boogie - delay with mono setting in 90 BPM tempo, repeated at quaver triplets intervals

•	M 1/32 (2t) Riff - a delay with mono setting in 57 BPM tempo, with a fine dynamic nuance repeated in demisemiquaver rhythm, with the fourth, sixth and eighth demisemiquaver left out.

•	S Image- setting the maximum possible BPM delay (700) and minimum repeat interval (sextuplet) we stop perceiving the delay as repetition and start perceiving it as an extension of the stereo base of audio signal.

•	S Room 1 - a similar effect as with the S Image preset but setting a lower BPM and a higher decay value makes the room effect more pronounced

•	S Room 2 - a similar effect as with the S Image preset but setting a still lower BPM and a higher value of the repeat interval makes the room effect considerably more pronounced.


How to use the Quick Presets
How to use DSound Quick Presets

Control:

   The panel called Quick Presets/Compare is a standard feature with all DSound plug-ins; it is located in the upper-right corner of the plug-in. Part of the panel is the display and four buttons marked 1, 2, 3, and 4. The display has 4 lines numbered the same as the buttons, i.e. 1, 2, 3, and 4. The number on the display is followed by the name of the preset stored at this moment under the respective buttons. The currently active preset is displayed in yellow colour while the non-active presets are displayed in grey colour.

 A single click of the left mouse button on the  control panel buttons will switch up to 4 presets stored under the given buttons, which provides for very fast operation with 4 presets.

Active after starting the plug-in  is the preset which was the last to be selected from the Quick Presets/Compare. panel. This only holds if the host application does not inject its own preset. It is therefore necessary to store the newly created preset before closing.

 If the host application does inject its own preset, the name of the last selected preset is marked with an asterisk and displayed in white, which provides information on the current change in the set up of control elements of the active preset.

Quick Preset menu:

   When selecting, storing or deleting parameters of the plug-in under buttons 1 to 4 of the Quick Preset/Compare panel the right mouse button is applied, which will call the following menu.

 The first part of menu contains the item Save for storing immediately the parameter under the current preset name; the initial active preset will be overwritten. The item Save As will open the dialog for storing the new preset, with the possibility of setting the preset name; the initial preset remains retained if it is stored under another name. The item Delete will erase the given preset. The second part of menu contains the item New, which creates a completely new preset with a varied number of presets. Presets stored by the user appear under the item User Presets. The item Built-In Presets contains presets supplied by the manufacturer, which cannot be changed. They can only be used and any possible change in parameters must be stored under another name by means of Save As. For a given preset number the name of the preset is marked [image]. The last item, What Is This?, refers to Help.

Another possibility how to save quickly a new preset is to use the combination of the Shift key and the left mouse button on one of the buttons 1 to 4 of the Quick Preset/Compare panel. Holding the Shift key and simultaneously depressing the left mouse button on the selected button of the Quick Preset/Compare panel will open the dialog for saving the new user preset Save As. The new preset will appear on the display under the selected button of the Quick Preset/Compare panel and also in the User Presets Panel.


How to use the Compare
How to use Compare

   When using the button Compare (marked C), it is first of all necessary to select from 4 presets stored under buttons 1 to 4 of the Quick Presets/Compare. The preset can, of course, be selected as the Built-In Preset, or the User Preset or also as the preset that has just been newly stored. It is with this selected preset that the later changes in the setting of control elements will be compared.

 Selected for illustration has been the preset under button 1, as shown in the picture. The preset is selected by clicking the mouse on button 1. On the display of the Quick Presets/Compare the activated preset shows in yellow colour. When the preset has been selected, button C is not active because the change in the control element setting has not been performed yet.

 After the first change in the setting of plug-in control element has been performed, button C is activated and the picture on the panel display changes. The initially activated preset will be lighted in white on the display and an asterisk will appear before the name of preset. This shows which preset is initially started from.

 With button C activated, a comparison can be made between the current setting of control elements and the initially selected preset. This will show in the following way: Buttons 1 to 4 of the Quick Presets/Compare panel will cease to be active, any change in the setting of control elements is forbidden, and on the display of Quick Presets/Compare panel the name of the initially selected preset will be lighted in yellow.

How to use the right mouse button

Slider:

   When working with the slider it is of advantage to use the right mouse button for copying the parameter values. When clicking the right mouse button on these control elements, the following menu will appear, depending on the type of slider:

 The Left->Right item is active only when processing a stereo signal and it copies the settting of the left channel into the right channel. The same holds for the Right->Left item but in reverse order. In this way the values of parameter setting can accurately be tranferred between the channels of the plug-in. The Swap Channels item enables swapping the parameter settings of the left and the right channel if the values set are different. The last item, What Is This?, refers you to the Help.

 The A -> B item is always active and it copies the setting of channel A into channel B. The same holds for the item B -> A but in reverse order. In this way the values of parameter setting can be transferred accurately between the channels of the plug-in. The Swap Channels item enables swapping the parameter settings of channel A and channel B if the values set are different. The last item, What Is This?, refers you to the Help.

Quick Presets panel:

   When selecting, saving and deleting plug-in parameters under buttons 1 to 4 of the QuickPresets/Compare panel the right mouse button is used to call the following menu:

 The first part of the menu contains the Save item for immediate saving of a parameter under the current preset name; the initial active preset will be overwritten. The Save As item opens the dialogue for saving the new preset with the option of keying in the preset name; the initial preset will be preserved if it is saved under a new name. The Delete item will delete the given preset. The second part of menu contains the item New, which creates a completely new preset with a varied number of presets. Presets stored by the user appear under the item User Presets. The Built-In Presets item gives the presets supplied by the manufacturer and they cannot be changed. They can only be applied and any change in the parameters must be saved under another name by means of Save As. For the given preset number the preset name is denoted [image]. The last item, What Is This ? , refers to the Help..

Buttons:

 Pressing the right mouse button over the plug-in function buttons will yield a simple menu containing the item What Is This?, which refers you to the Help of button function.

The other plug-in parts:

   Clicking the right mouse button at a point of the plug-in other than in the preceding cases will open the following menu:

 The first item of this menu will open the Quick Preset Manager, the first six items of which correspond to the Quick Presets menu, which has been described above.

 The Save To File item opens a dialogue that allows all user presets to be saved to file in the *.dpa format (DSound presets archive), which provides for transferring all the created presets to another computer. Conversely, the item Load From File provides for opening the presets stored earlier in the text file and using them in the plug-in. The last item, Delete All Presets, will delete all user presets.

The next item, called Generate Tail, is only functional if used in the Sound Forge or Samplitude host application. The Output Format item allows a change in the output format of the signal processed only if the plug-in is connected to the mono track. The initial output format is set up as stereo. If the host application does not support the mono->stereo format change of the signal processed, the plug-in cannot be connected to the mono track. If the plug-in is connected to the stereo track, the signal output format cannot be changed and the output format is stereo. The item Help opens the themes of the Help for the whole plug-in or a set of plug-ins. The last item, About ..., opens the window with basic information on the plug-in and provides quick access to the www-browser and the local www page.

How to use the keyboard

   The keyboard can be used to control only those control elements that can be chosen and activated with the key Tab, that is to say the slider and the switch. To control an active control element the following keys can be used:

      Upward Arrow or Forward Arrow will increase the control element value by the least possible change. This change is less than the least change obtained with mouse control. It is described as D1 in the Help for the function of control element (What Is This?).

      Downward Arrow or Back Arrow will reduce the control element value by the least possible change. This change is less than the least change obtained with mouse control. It is described as D1 in the Help for the function of control element (What Is This?).

      Page Up will increase the control element value by a major change; the value of this change can be different for different control elements and it is described as D2 in the Help for the function of control element (What Is This ?)

      Page Down will reduce the control element value by a major change; the value of this change can be different for different control elements and it is described as D2 in the Help for the function of control element (What Is This ?)

      Home has a double function, depending on the type of control element:

For the control elements Decay, Pan Wet:

It will set the control element value to the least possible value.

For the control elements Dry Out, Wet Out:

It will set the control element value to 0 dB.

      End has a double function, depending on the type of control element:

For the control elements Wet Out, Decay, Pan Wet:

It will switch cyclically between these control elements.

For the control element Dry Out:

It will set the control element value to minus infinity dB.

      Delete switches the active states of the control element if a stereo ssignal is being processed or if we are concerned with the two-channel slider. The switching takes place in this order: left channel (A), right channel (B), and both channels.

      Insert makes it possible to set directly the parameter value of the active control element.

Control element Tempo:

   The keyboard can also be used to control the Tempo control element, provided it is activated by the mouse or by the Tab key. To control the active Tempo control element, the following keys can be used:

      The up arrow will increase the value of tempo setting by 1 BPM.

      The down arrow will reduce the value of tempo setting by 1 BPM.

      The right arrow will increase the value of tempo setting by 0.01 BPM.

      The left arrow will reduce the value of tempo setting by 0.01 BPM.

      The Page Up key will increase the value of tempo setting by 10 BPM.

      The Page Down key will reduce the value of tempo setting by 10 BPM.

      The Home key resets the setting of BPM hundredths, it corresponds to the Clear Detail button.

      The Insert key provides for setting directly the BPM value.

   A very important key is the Shift key. It is used for the control of the slider when processing a stereo signal or when controlling the two-channel slider   (the latter is given in parentheses). This key provides for setting the left (A) and the right (B) channel independently of each other. If, for example, we want to set the left channel (channel A) separately, we first press the Shift key, hold it, then use the mouse to select the control element part with the green (blue) LED, and using the mouse or the keyboard we set the required value of left channel (channel A) setting. The same procedure is used when setting independently the right channel (channel B), with the differeence that using the mouse we select the control element part with the red (orange) LED.

   For independent control of the left and the right channel (of channels A and B) the Delete key can also be used. Pressing repeatedly the Delete key we successively activate the left channel (channel A), the right channel (channel B), and both channels of the active control element.

How to work with the slider

Processing a mono signal:

   When processing a mono signal the plug-in detects this format and the sliders are as follows. The first picture gives the passive slider, the second picture the active slider.

Processing a stereo signal:

   When processing a stereo signal, the plug-in detects this format and the sliders are as follows. The first picture gives the passive slider, the second picture the active slider.

Control of two-channel slider:

   The appearance of the two-channel slider (channels A and B) is independent of the format of the signal processed and is as follows. The first picture shows the passive slider, the second shows the active one.

Description:

   The slider has always a scale with two values, which correspond to its setting limits. The slider grip has a light-emitting diode, which distinguishes between slider states. If the LED is on, the slider is active, if it is off, the slider is passive. The slider grip for setting the left channel is green, that for setting the right channel is red. The grip of the slider for setting channel A is blue while that for setting channel B is orange. The current setting value is shown on the display located in the plug-in. In case the given slider is active, its current setting value will also be lighted on the display. The display also shows the unit corresponding to the parameter that is being set.

Mouse control:

   The slider is selected by clicking the left mouse button on any point of the path or on the grip. The required parameter value is set by holding the left mouse button on the grip and dragging subsequently in the direction of desired change. When it is necessary to control separately the left and the right channel or channels A and B, use the Help section Independent setting of the left and the right channel or Independent setting of channels A and B.

Keyboard control:

   Use the Help section How to use the keyboard to set the parameters.

Setting directly the value of slider setting:

   A double click with the left mouse button on the slider selected will open the window for direct setting of the control element value. The first picture shows the window when processing a mono signal, the second picture when processing a stereo signal and the last picture shows the edit box for controlling the two-channel slider.

   For the mono signal the window contains one edit box, for the stereo signal the window contains two edit boxes; when controlling the two-channel slider the window has also two boxes. The first box gives the left channel (channel A) setting, the second the right channel (channel B) setting. The values of the left (A) and the right (B) channel setting can be edited independently. For editing, the newly set values must be confirmed by the Enter key. If the newly set values are not satisfactory, the are cancelled by the Esc key.

   To set the slider setting value directly the Insert key can also be used. Pressing the Insert key will open a window in dependence on the type of control element. Then we proceed as described above.

Right mouse button:

   When working with the slider it is of advantage to use the right mouse button to copy parameter values. After clicking the right mouse button on this control element the following menu will appear, depending on the type of slider:

 The item Left->Right is only active when processing a stereo signal and it copies the left channel setting into the right channel. The same holds for the item Right->Left but in reverse order. In this way the values of parameter setting can accurately be transferred between plug-in channels. The Swap Channels item enables swapping the parameter settings of the left and the right channel if the values set are different. The last item, What Is This?, refers you to the Help.

 The A -> B item is always active and copies the setting of channel A into channel B. The same holds for the B -> A  item but in reverse order. In this way the values of parameter setting can be transferred accurately between the channels of the plug-in. The Swap Channels item enables swapping the parameter settings of the left and the right channel if the values set are different. The last item, What Is This?, refers you to the Help.


Compare

Compares the setting of current parameters with that of the parameters of last selected preset. Control command.


Quick Preset

Selects the effect parameters that have been stored in advance under the given Quick Preset number. Control command.


Preset Name

Displays the name of active preset.


Independent control of the left and the right channel

   For an independent control of the left and the right channel the key Shift is used. This key provides for setting the left and the right channel independently of each other if a stereo signal is processed. If, for example, we want to set the right channel separately, we first press the key Shift, hold it down and with the mouse we select the control element part containing the green LED and then, using either the mouse or the keyboard, we set the required value of left channel setting. The same procedure holds for independent setting of the right channel with the difference that using the mouse we select the control element part with the red LED.

   After pressing the key Shift we can change the setting of the left and the right channel simultaneously even if they are not set identically. The difference between the setting of the left and the right channel remains retained as long as the limit positions of the control element are not exceeded. After subsequent change of the setting from the limit position to another position the initial difference is restored (this only holds for mouse control).

   If we want to cancel the difference between the setting of the left and the right channel, we can use the right mouse button and call the menu that provides for copying the left channel setting into the right channel or vice versa.

   For independent control of the left and the right channel the Delete key can also be used. Pressing repeatedly the Delete key we successively activate the left channel, the right channel, and both channels of the active control element.

   Another method of controlling independently the left and the right channel is setting directly the value of slider setting.

 Double clicking the left mouse button on the slider will open the window with two edit boxes. The first box gives the left channel setting, the second the right channel setting. The values of left channel and right channel settings can be edited independently of each other. After editing, the newly set values of left channel and right channel settings must be confirmed with the key Enter. If the newly set values are not satisfactory, they can be cancelled with the key Esc.

   To set the slider setting value directly the Insert key can also be used. Pressing the Insert key will open a window in dependence on the type of control element. Then we proceed as described above.


Independent control of channels A and B

   To control independently channels A and B the Shift key is used. This key makes it possible to set channels A and B independently of each other if the plug-in algorithm provides for processing by two independent channels (be careful not to confuse this with processing a stereo signal). If we want, for example, to set channel A independently, we first press the Shift key, hold it and, using the mouse, we select the control element part with the blue LED and then set the required channel A value, by means of either the mouse or the keyboard. The same holds for setting channel B independently, with the difference that we select the control element part with the orange LED.

   On pressing the Shift key we can change the setting of channels A and B simultaneously, even if they are not set identically. The difference between the setting of channel A and channel B remains preserved as long as the limit values of the control element are not exceeded. When the setting is subsequently changed from the limit value to another, the initial difference is restored (this only holds for mouse control).

 If we want to cancel the difference in the setting of channels A and B, the right mouse button can be used to call a menu which enables copying the setting of channel A to channel B, or vice versa.

   For independent control of channels A and B the Delete key can also be used. Pressing repeatedly the Delete key we successively activate the channel A, the channel B, and both channels of the active control element.

   Another way of controlling independently channels A and B is to set the slider values directly.

 Double clicking the left mouse button on the slider will open a window with two edit boxes. The first box gives the setting of channel A, the second that of channel B. The values of the setting of channels A and B can be editied independently. After editing, the newly set values of channels A and B must be confirmed by the Enter key. If the newly set values are not satisfactory, they are cancelled by the Esc key.

   To set the slider setting value directly the Insert key can also be used. Pressing the Insert key will open a window in dependence on the type of control element. Then we proceed as described above.


How to use the Control element Tempo
How to work with the control element Tempo

The Tempo control element consists of several components as shown in the picture.

 In the centre is the display which shows the current BPM (Beat Per Minute) value in the format: integer plus hundredths of BPM. The integer part of BPM is set by means of buttons below and above the display, which provide for increasing or reducing the setting by a minimum of 1 BPM. Hundredths of BPM are set by the Detail buttons, which are located on either side of the display, but only in the range of +/-1 BPM. The bottom-right button, Clear Detail, resets the setting of BPM hundredths. Thus if the Clear Detail button was used, what remains is the integer value of BPM.

Mouse control:

   Clicking the left mouse button on the buttons around the display will increase or decrease the BPM value by 1 BPM or by 0.01 BPM, depending on the button marking. If we continue holding the mouse button on the buttons, the value of BPM setting will be changing continuously in the required direction.

   On double-clicking the left mouse button over the display or on pressing the Insert key the following edit box appears:

 The edit box is used to set the BPM value with an accuracy of two decimal places. After editing, the newly set values must be confirmed by the Enter key. If the newly set values are unsatisfactory, they are cancelled by the Esc key.

Keyboard control:

   The keyboard can also be used to control the Tempo control element, provided it is activated by the mouse or by the Tab key. To control the active Tempo control element, the following keys can be used:

      The up arrow will increase the value of tempo setting by 1 BPM.

      The down arrow will reduce the value of tempo setting by 1 BPM.

      The right arrow will increase the value of tempo setting by 0.01 BPM.

      The left arrow will reduce the value of tempo setting by 0.01 BPM.

      The Page Up key will increase the value of tempo setting by 10 BPM.

      The Page Down key will reduce the value of tempo setting by 10 BPM.

      The Home key resets the setting of BPM hundredths, it corresponds to the Clear Detail button.

      The Insert key provides for setting directly the BPM value.

Warning for Cubase VST and Wavelab users

Important notice:

   In case that the host application is, for example, Cubase VST, whose keys given in the Help How to work with keyboard to set parameters have already been set for its own functions, the control via keyboard will not function directly. In order to be able to use a quick and effective keyboard control it is necessary to use the Ctrl key. This means that instead of depressing, for example, the Page Up key we first depress the Ctrl key, hold it and subsequently depress the Page Up key. In this way the same result is achieved as in applications where the keys have not been set (e.g. Sound Forge).

The Tab key for switching between active control elements is nonfunctional in the Cubase VST application.

The Del key is functional only when the parameter 'Plug-Ins receive key commands' has been activated in the Cubase VST application setting.

The Wavelab 1.6 application does not support keyboard control of parameters.
