Perkons Voice

Erica Synths

Eurorack incarnation of the percussion voices from the PERKONS HD-01 Drum machine, featuring a digital sound engine followed by an analogue multimode filter and overdrive. 13 sound generation algorithms, up to 99 user presets, 1V/oct tuning, 4-voice poly overlap mode, and drone mode.635

Capabilities 2

Drum Voicedrum-voice
13 algorithm digital drum voice with analogue multimode VCF and overdrive. Up to 4-voice poly overlap mode. 99 user presets.635
Preset Storagepreset-storage
Up to 99 user presets storable and recallable via PATCH button and encoder. PATCH CV input can navigate through occupied patch slots.635

Jacks 9 — 8 in / 1 out

NameSignalVoltageDescription
Inputs (8)
ACCcv≥1VAccent input. Any signal above 1V increases the percussion volume by 2 dB.635
C-OFF CVcv635
DECAY CVcv635
DRIVE CVcv635
P1 CVcv635
P2 CVcv635
PATCH CVcvConfigurable CV input for patch selection. Can be set to unipolar 0-+5V, bipolar -5V-+5V, or 1V/Oct. Patch changes on incoming trigger only.635
Assignable destinations
UNIPOLAR0 to +5V range, navigates through up to 60 occupied patches635 BIPOLAR-5V to +5V range, navigates all saved patches with 0V assigned to the middle patch635 1V/OctQuantized 1V/Oct setting for sequencer-driven patch selection at precise moments635

Parameters 9

NameTypeRangeBehavior
ALGObuttonActivates 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
CUTOFFknobSets the initial cutoff frequency of the VCF. Incoming CV from C-OFF CV is added to the potentiometer position.635
DECAYknob635
DRIVEknobSets the initial overdrive amount. The incoming CV from DRIVE CV is added to the potentiometer position.635
PARAM 2knobSets 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
PATCHbutton1 – 99Activates 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
TRIGbuttonManual trigger button for firing the drum voice without an external trigger signal.635
TUNEknobSets the initial tune of the drum. The incoming CV from TUNE CV is added to the potentiometer position. Tuned to 1V/oct.635
VCFbuttonSelects between Lowpass, Highpass, and Bandpass filter modes. The screen and LED brightness indicate the selected mode: LP (bright), HP (dim), BP (off).635
