audionerd/acid

a tb-303-style sequencer for crow + x0x-heart + grid

influenced by Julian Schmidt’s “Analysis of the µPD650C-133 CPU timing”

designed for use with the open source x0x-heart + pacemaker

connections

crow out 1 → x0x-heart cv
crow out 2 → x0x-heart gate
crow out 3 → x0x-heart accent
crow out 4 → x0x-heart slide

clock → crow in 1 (optional)

sequencing

playhead row shows current step during playback, and a cursor for the currently selected step when editing.

for each step:

• gate/accent can be off, gate on, or accent on
• slide can be off or on
• up/down set the octave of the note

hold meta and select a gate/accent step to immediately turn it off.

left/right moves the cursor between steps. the keyboard will display the note assigned to the step, which can be changed by pressing a keyboard key.

future

• save/load patterns
• range selection
• crow "satellite" mode (allow continued playback disconnected from norns, re-connect to edit pattern)
• random pattern generation
• MIDI out support
