Bocuma Sum0
Introducing SUM0, a voltage-controlled oscillator with expanded harmonic possibilities, in a Eurorack format.
The 4 classic waveforms are generated by a meticulously designed oscillation engine.
You can modulate its frequency and its pulse width thanks to its integrated LFO, capable of reaching audible frequencies to achieve expressive modulations with the simple touch of a switch.
Expand the voice of your system by creating complex waveforms and high harmonic content thanks to its output mixer. This mixer also has an input to integrate an external signal to the mix output.
Of course, all its parameters (FM, PWM, SYNC, V/OCT) are at your fingertips through its patch points on the front panel.
- Width: 22HP
- Depth: 26mm
- Power: 12mA @+12VĀ / 12mA @-12V
