The Miscellaneous Channel Settings page contains various generator settings. These settings appear in all generators (including third party ones).
There is also one more section that will appear in this window if you load a SimSynth preset in the sample bank of a Sampler:
Check the Use Riff option if you want to generate the whole riff in the preset (this option is disabled if the preset you used does not contain riff data). The Tempo wheel lets you set the tempo of generated riff.
Using Cut/Cut By you can set triggering of a note in one channel to cut notes in another one. To do this you set the Cut value (the LCD on the left) to some number in the channel that will cut notes and then set the Cut By value (the LCD on the right) to the same number in another channel (that will be cut from the first one). FruityLoops will not detect if the Cut value is set to the same number in several channels, so you may freely create any combination to suit your needs. You can also make a channel to cut itself - just set its Cut/Cut By values to the same number. FruityLoops will do this automatically (finding unique numbers, not used in other channels) if you check the Cut Itself button.
Please note that cutting just sets all notes' envelopes to release state. So if release you set is long, you will still hear a note fading out after it was cut.
This section will not appear in the TS404 generator, because it uses different approach for generating its sound.
This function plays randomly notes from a channel through group of other channels. It is particularly useful for creating more natural beats. You can create snare loop in a channel and then set this loop to be played randomly by this and several other channels that hold similar snare samples. To use this feature, select all channels you want to mix with in the Step Sequencer. Then click the Set button. You can later click Get button and all channels in the random mix group (current channel belongs to) will be selected.
This section will not appear in the TS404 generator, because it uses different approach for generating its sound.Polyphony settings can be used to set the max polyphony each generator can use. Setting this option (the LCD) to a lower number reduces the amount of CPU used to play the song. If the LCD displays dashes, this means that polyphony is not restricted to any number.
Clicking the Mono button sets the generator to monophonic mode. Then the LCD will be replaced by a wheel. The more you turn this wheel to right, the longer notes in the generator will slide from one to another, when they overlap in the Piano Roll (note slide is not supported by VSTi generators and may not be supported by some external generators).
This section will not appear in the TS404 channels, because it works only in monophonic mode.
These settings appear only in the Sampler, when a DrumSynth preset is used to fill the sample bank in Sampler Channel Settings. They are few parameters that define the generated sound and they are identical to the same options in DrumSynth standalone application.
The testing keyboard lets you preview how the generator sounds - just left-click any of the keyboard buttons. You can also preview using your typing or MIDI keyboard. The testing keyboard also has one important function - right-click a keyboard button to set the base note for a sample (the appropriate button will light up). Since each sample has particular pitch (except probably noise samples), FruityLoops needs to know how to interpret it - when you set the base note to C6, FruityLoops maps pitches considering that when played at its original speed, sample has pitch of C6. All other notes are generated by changing sample's speed (and thus changing its pitch). So actually setting the base tone higher makes all notes sound lower. For example if a sample has pitch C5, and you map it to C6, FruityLoops will consider that C5 sample as C6, thus shifting all notes one octave down.
The bar above the testing keyboard contains some additional options:
