I posted the video sample and details of that Hollow Earth pedal I built a couple weeks ago on about 5 forums. It went slightly viral on a few others thanks to a few users. Anyways, interest in it has been a little overwhelming! So much so that I've convinced myself that I should build a batch of revisions of this to spread around.
Things I'd like to add/change:
-Eight to ten presets, all overwritable with your own shapes
(with LED digit display)
-Expression-in for the shaping
-Expression-out to "shape" other effects
-Rugged footswitch for record instead of the flimsy button
-Triggered envelope mode
-Sample input as waveshape
(the last one is a biiiig maybe)
After a 10-day break from this stuff to play jams/gigs, I started tinkering again. I got random mode mostly working, and I've started the preset saving bit. 8 pin DIP 24LC eeproms are a wonder!
