Features and functions

Three Alloguing VCO with suboscillator - Deep, Hot bass
Suboscillator - extra vinegar under base ton for maximum bass depth
32-step sequencer - longer and more complex bass lines than other Volca
Korg Lader Filter - 12dB / octave subtractive sound with resonance
ADSR / AD Envelope - amplitude and filter modulation
LFO - Pitch modulation, amp, filter (0.15 Hz - 20 Hz)
VCA Analog - dynamic volume control and expressivity
Battery + USB power supply - 40-50 hours on AA batteries
Sync IN / OUT - synchronization with other Volca units and devices
CV / Gate inputs - external control from Eurorack or other synths
Audio outputs - LINE OUT (3.5 mm TS) + Headphones
Compact design - 188 mm × 110 mm × 60 mm
Deadman switch - security switch for random start
Analytical sound - warm, organic bass without digital noise
Ideal for - electronic music (acid, techno, house), experimental bass

Typical routing

Sync with others Volca: Volca Bass as Master Clock
• Set Volca Bass pace to ~ 120 BPM
• Sync OUT → other Volca Sync IN
• All units play synchronous
• Bass OUT + others to the mixer
