Hi,

I've been experimenting with overriding the internal polyphonic voice assignment scheme of the G2. In other words: Yes, it can be done Smile, and among many things, it opens up the arena for all kinds of DIY arpeggiator possibilities.

I made a 4-voice polyphonic pattern arpeggiator some time ago, which used a bubble-sort technique to allocate the voices correctly. This is a cumbersome affair, and the sorting circuit doubles in volume with every extra voice. 8 voices? Forget it.

Until now. Smile Here's an 8-voice version, based on a completely different approach. A DIY scanning circuit detects keys played on the keyboard, assigning to them consecutively to a voice of the 8-voice sequencer. The scanning process can be selected either up-down or down-up, arranging the voices top-down or vice versa, as you wish.

The patch in the presented form is intended to control other synths/slots. However, you can easily remove the MIDI note send module in the voice area and patch your own polysynth there and hook it up accordingly (note, gate).

The controls are pretty self-explanatory.

As I say, this patching technique enables all sorts of DIY arpeggiator schemes. Sweep a played keyboard range with an LFO? No problem. More to come (when I have time).

cheers,
t

UPDATE: I isolated and documented the underlying technique and posted it as a building block. It enables you to realise any kind of arpeggiator scheme.
