This is APCX come full circle- the first version inspired the architecture of the noisebot/grainbot synths, and now APCX2 adopts their architecture for a dual-APC osc noisebox synth.

To add to the fun, there is a modulation matrix with a range of sources & destinations. There is also a "combiner" which uses various math formulas to combine two mod sources in various ways.

Another interesting feature is the "data corruption" effect, which adds another level of chaos to the mix. This is something like a software circuit bend which taps the audio stream at several points along its path, randomly mangles the signals in various ways (which are affected by various combinations of control signals from the synth's modulators) & mixes the mess back into the output.


USING MIDI WITH THE APCX2:
--------------------------

One key element that should be mentioned before you go about experimenting: these synths do not use MIDI control in the usual way. You will notice there is a mod source labeled "key"- this source tracks incoming MIDI pitch. There is also a switch near the upper right (for the full version- beneath the "sg" logo, to the left of LFO1) labeled "MIDI gate", which will only allow sound through when a key is pressed (or the synth recieves MIDI notes from a sequencer, etc.) when it is turned on.

Since the noisebots are monophonic, if you assign the "key" mod source to a pitch-related parameter (or multiple such parameters), and turn the MIDI gate on, you can get something resembling normal MIDI control. The one difference is this: if you play overlapping notes, the second note will sound as expected- however, if you continue holding the first note, and let go of the second while it's still playing, all sound will get cut off when you release the second note.

There is a second side-effect to this setup: with the MIDI gate turned off, keytracking is still available as a modulation source. This means you can use MIDI notes from your keyboard/controller or sequencer to change parameters while the sound plays continuously, and that value will continue being sent until you press another key.


Modulation guide:
-----------------

Due to size constraints, the labelling of the mod destinations may be a bit cryptic. Here's a guide.


rm1lvl: level of ring modulator 1 (apc 1 carrier, apc 2 modulator)

rm2lvl: level of ring modulator 2 (apc mix carrier, RM osc modulator)

RMfrq: frequency of the RM osc

RMmr: mod rate of the RM osc

RMma: mod amount for the RM osc

These last 3 destinations can also be switched to modulate the following parameters:

g2max: max frequency of gen 2

g2min: min frequency of gen 2

rm1dp: ring modulator 1 depth

rm2dp: ring modulator 2 depth

hicut: hi cut filter cutoff frequency
