So this is the third iteration of something I've been working on since yesterday. I had a tough time making it sound musical... it was a cool idea technically, but difficult to impliment musically.

It is 2 sets of PM oscs (both with a modulator and carrier), each with it's own pitch value table. The tables hold 8 settings each for semitone value of the modulator and have their own Crossfader. The idea was a sort of wavetable type synthesis where you could have different PM stuff going on.

In the OSC section there is a manual crossfade control with variable fade smoothing... so you can make it so it steps hard from one value to the next, or fades slowly or anything in between. This makes for some strange and crazy pitch sliding effects over time. Additionally, each crossfader has an LFO attached to it that syncs to BPM for time sequenced type sounds. Each Mod-Carrier set has it's own level setting and ADSR amp envelope. Additionally, there is a special PAN feature I made which resembles the Osc panning on the DSI Evolver. Essentially, turning the PAN value to the far left will pan one of the oscs hard left, but the other will be panned hard right... conversly, turning pan to the far right will alternate one osc from the hard right to the hard left and of course opposite for the other. Additionally, there is separate beat synced LFO for the pan value as well.
The OSC section also contains controls to set up your semitone tables, 8 variables for each osc which are crossfaded through, Osc set 1's are on A2 and Osc set 2's are on A3. The second OSC has an additional static control on page A1 for semitone control of the second osc set's carrier... this can be used to offset the range of the second osc set from the first which I find useful for pad sounds. You can then add strange sparkling sounds on top of a pad for instance.
