Hopefully I'll be able to test it some time this Autumn. Below is the current graphic displayed with a gerber viewer (won't be so colorful). The red sections would be exposed FR4 backlit by LEDs.
The system clock parameter doubles as a program selector when in momentary bypass. Additional footswitch to maximize the looping. Ditching the grain direction switch and instead offering both forward and backward granular delay/stretching. Random vibrato (MOD) to make it more lively. The core schematic for this thing is laughably simple so it was fun to see how much functionality I could squeeze into it without adding too much extra circuitry.
Feedback is welcome

CLOCK can also be used to adjust the pitch of audio in the delay buffer (see Magpie Crystal Math for similar stuff). Both the wet and dry path will be completely digital (like the last version) so the CLOCK parameter will affect the dry signal too (sample rate resolution, high frequency content).

Seems like it might be a little tight for stomping if that's the case but maybe not. Might be better in the 1590BB size box if its getting two foot switches. Stoked on the extra functionality!

Just LED indicators. The CLOCK pot would be used to switch the settings like this:
Pedal is active/engaged -> Hold down bypass switch -> Rotate CLOCK pot from ~mid to ~min -> Direction LEDs change (forward or backward)
Alternatively rotating CLOCK pot from ~mid to ~max would change the Octave LEDs (down, standard, up). Moving between mid - max - mid - max would cycle through the octave options.
I don't know if it will be too cumbersome or complicated. Will have to build the hardware and test how it "feels" in real life.
