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.

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.

MemPot is a small controller circuit where potentiometer (or any variable resisor) is read and recorded with PIC (16F819) microcontroller. PIC stores a sequence of values from the user turning the knob and plays the same sequence back via serially controlled digital potentiometer (DS1267) chip. The playback speed and recording buffer can be controlled. This is a handy tool for performing gestures with electronic instruments with variable resistors as controllers.
Check the updates on schematics, PCB-files and Bill of Materials from here. We can hopefully include the making of MemPot for our next DRU workshop in July.
