Dual Folded (Sledgehammer) Arpeggiator

[jamos]

I'm always on the hunt for good arpeggiators, and since the G2's (frankly) stinks, I decided to roll my own. I tried to make use of Tim Kleinert's elegant scanning arp engine, but I was unable to figure out how to get it to extend over multiple octaves... so I decided to take a brute force (sledgehammer) technique and use individual note detectors driving note quantizers. Alas, that only allowed for two octaves of key detection, even without adding many features... then I hit on the idea of using MIDI zones to fold all octaves of the G2X keyboard into a single octave of detectors... hence the name.

This patch provides two synced but otherwise independent arpeggiators. The two note quantizers track the keyboard, and are driven by a trio of LFOs, with a pair of level sequencers for velocity. This part of the patch is all in blue; this should make it easy to rip that out and replace it with whatever modulation scheme you like: sequencers, wheels, whatever.

Sadly, the note detectors do not recognize the KB Hold or Sustain controls, so there's a custom Latch circuit to do that.

Presented as a performance with two simple voices in slots B and C, just so you can hear it. Have fun.
