I'm working on a "pick attack", I'll have something this year. It's not hard to implement; more a matter of testing different designs for sound qualities, and deciding exactly how to fit it into the modular scheme. Right now I'm testing a filter that can function similar to the Wal (in the schematic above) but a different topology that can do other things as well. My goal isn't to copy a Wal, but it should sound pretty close when tuned the same.
