Parameters 9

Name	Type	Range	Behavior
ALGO	button	—	Activates algorithm selection mode. The letter indicates the algorithm and the digit indicates a variation within the algorithm. Rotate the encoder to select; push encoder to choose between MONO and POLY mode.635
CUTOFF	knob	—	Sets the initial cutoff frequency of the VCF. Incoming CV from C-OFF CV is added to the potentiometer position.635
DECAY	knob	—	635
DRIVE	knob	—	Sets the initial overdrive amount. The incoming CV from DRIVE CV is added to the potentiometer position.635
PARAM 2	knob	—	Sets the initial PARAMETER 2 value for the active algorithm. Meaning depends on the selected algorithm. Incoming CV from P2 CV is added to the potentiometer position.635
PATCH	button	1 – 99	Activates patch selection mode. Rotate encoder and push to confirm selection. Hold encoder 2s to save. Hold PATCH + short press encoder to unload patch. Hold PATCH + long press encoder to delete patch.635
TRIG	button	—	Manual trigger button for firing the drum voice without an external trigger signal.635
TUNE	knob	—	Sets the initial tune of the drum. The incoming CV from TUNE CV is added to the potentiometer position. Tuned to 1V/oct.635
VCF	button	—	Selects between Lowpass, Highpass, and Bandpass filter modes. The screen and LED brightness indicate the selected mode: LP (bright), HP (dim), BP (off).635
