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 press a step’s gate/accent to immediately turn it off.

hold meta and press a step’s top row to select that step.

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.

to set a loop of less than 16 steps, hold a key on the top row for the start point, and press another key on the top row for the end point. the loop will run between those steps.

Patterns can be saved, loaded, overwritten, and removed via the PARAMETERS menu.

future

• crow "satellite" mode (allow continued playback disconnected from norns, re-connect to edit pattern)
• random pattern generation
