Nandsynth with groovebox+xoxbox clock



Nandsynth synced by Groovebox->midi->xoxbox->gate->SwitchSequencer. The 555timer is just replaced by the xoxboxes cv/gate trigger. Much to my astonishment it worked.

Just Nandsynth audible in the beginning, simple beat and more or less unaudible xoxbox bassline opened in the end.

Instructions of the first version of the Nandsynth here.

MemPot, controlling xoxbox



Memory Pot controlling xoxbox. The two RCA connectors on the side of the xoxbox just connects to the filter cutoff and custom resonance boos pots inside the xoxbox. MemPot box records realtime the turning of the pot and plays it back with adjustable speed.

See other MemPot examples here, and instructions to make one here.
