Behaviors

CV target cycling CV Assign button press

Each press of the CV Assign button advances the CV routing: pitch → decay → volume → sample-select. LED colour reflects the current target.

Chromatic sample-select CV Assign = sample-select · CV = 1V/oct

When assigned to sample-select, incoming CV advances the sample in semitone steps at 1V/oct, turning drum 1 into a pitch-addressable 64-slot sample player.

Exclusive retrigger simultaneous TRIG 1 + TRIG 2 · Exclusive on

Exclusive switch defines whether simultaneous triggers let both voices overlap or cut one for the other — crucial for kick/hat choke behaviour from a single step sequencer.

Custom sample upload USB programmer device

The separate Pico Drum Programmer loads user WAVs into the module's 8MB flash via USB. Each bank still caps at 64 samples per drum.

Preset save/load long-press Sample buttons

Up to six combinations of sample selections and parameter settings can be saved as presets and recalled during performance.

Controls

drum 1 Pitch 1 Sets playback pitch of drum 1's sample. Under CV assignment also becomes the 1V/oct chromatic control.
Wide pitch range · negative tuning possible
drum 1 Decay 1 Truncates sample tail via internal envelope. CCW: very short · CW: full sample length.
Per-trigger VCA decay
drum 1 Level 1 Output level for drum 1 on the mixed output.
CCW: muted · CW: full gain
drum 1 Sample 1 / Bank button Selects one of 64 samples for drum 1. Short press steps; long press enters save/load bank.
64 factory samples · user samples via USB programmer
drum 2 Pitch 2 Playback pitch of drum 2.
Same range as drum 1
drum 2 Decay 2 Decay envelope for drum 2.
Per-trigger VCA decay
drum 2 Level 2 Output level for drum 2.
CCW: muted · CW: full gain
drum 2 Sample 2 button Selects one of 64 samples for drum 2.
No CV over sample-select on drum 2
drum 1 CV Assign Cycles which drum-1 parameter the CV input modulates; LED colour indicates the target.
Green: pitch · Red: decay · Orange/Yellow: volume · (4th): sample-select at 1V/oct
global Exclusive switch Sets how the two voices interact when triggered simultaneously (retrigger / mute / overlap).
