Soundfont Oscillator

The Soundfont Oscillator does only one thing, plays raw samples. It dosn't add any envelope or velocity response to the sample. You can add full control over volume, filtering and pitch externally. Use it as you would a standard Oscillator, i.e. it's now just the starting point of a patch. You also need at least a MIDI CV,an ADSR and a VCA to make it work. It has trigger, pitch and velocity inputs. One thing about the velocity input, it dosn't change the output volume. Soundfonts sometimes use velocity-split samples, i.e. one sample for quiet notes, one for loud notes. The 'Velocity' input is used to choose the appropriate sample from the soundfont. You still need to control the sound volume externally via a VCA. Because the SF Osc is controlled from a MIDI CV, you now get access to Portamento, Mono mode, and Retrigger controls. Portamento acts a bit weird if you glide over a wide range, as the sample has to be transposed much further than usual. The sample gets seriously warped (this is not a bug, just a consequence of the pitch shifting).

Inputs:

Bank - Provides external choice of bank. NOTE: Changing bank via external control only works while audio engine is running [ 1 ,2 , ]
Patch - Provides external choice of patch. NOTE: Changing patch via external control only works while audio engine is running [ 1 ,2 , ]

Soundfont Player

Plays standard .SF2 (Soundfont 2) samples. Currently only basic Soundfont features are supported. This is a polyphonic module, use it inside a container. Note: many soundfonts reference ROM Samples, assumed to be available on your soundard. SynthEdit doesn't have these, so you may encounter 'dead' patches in some soundfonts. Shareware such as 'Awave' can check a soundfont for ROM samples references. Use a 'Wave Player' module for wave files, *.wav

Inputs:

Distorts the input depending on a 'Transfer Function' you can draw. Can be used as a distortion unit, soft clipper, waveform modifier, or control voltage transfer function (eg velocity response curve).

Inputs:

Signal In

Outputs:

Signal Out

Parameters:

Ignore Program Change - Prevents this control responding to patch changes from 'Patch Select' module

WaveShaper2

Distorts the input depending on a 'Transfer Function' you specify. e.g sinx(x) + PI. Can be used as a distortion unit, soft clipper, waveform modifier,or control voltage transfer function (eg velocity response curve). Input is limited to -5.0 to +5.0 volts.Supported Math funtions: *,/,+,-,^,sin,cos,tan,asin,acos,atan,sinh,cosh,tanh,exp,log,log10,sqrt,floor,ceil,abs,hypot,deg,rad,sgn,min,max
