Features and functions
- 50 patch points - wide modular signal routing
- 8 modules (SOURCE / FUNCTIONS / WOGGLE / SPLIT / DUAL LPG / UTITY / SPACE OUT / Sequence)
- Pin patch system; in pack of 20 connecting pins
- Three analogous VCO - Sawtooth, square, triangle wave shapes
- Korg Lader Filter - 12dB / octave subtraction filter
- ADSR Envelope - amplitude and filtration modulation
- LFO - low-frequency oscillator (0.15-20 Hz)
- VCA - voltage-controlled amplifier for dynamics
- 12-step mini-keyboard - manual play and control
- 16-step sequencer - creating a model and melodies
- Sequencer: Motion Sequence, Active Step, Bounce and Stochastic Mode
- Normalize East - certain signals are defaulted
- Flexible Patch-based design - achieve any combination
- Battery + USB power supply - about 50 hours on AA batteries
- Sync IN / OUT - synchronization with other Volca / devices
- CV IN (TRS): left channel + -5 V, right channel 1V / oct (0 to + 6 V)
- Audio outputs - LINE OUT (3.5 mm TS) + Headphones
- Compact design - all modular elements in 188 × 110 mm
- Educational - Learn Modular Synthesis Without A Big Financial Deposit
- Experimental approach - limited size = focus on creativity
- Ideal for - patch design, modular experiments, sound design
