Batumi II
Four-channel wide-range voltage-controlled LFO with 1V/oct tracking, free/phase/divide/mult sync modes, twelve simultaneous waveform outputs per cycle, and per-channel reset and sync inputs.994
Capabilities 2
- LFOlfo
- Four independent voltage-controlled LFO channels with 12 simultaneous outputs, V/oct tracking to audio rates, and four sync modes.994
- Voltage-Controlled Oscillatorvco
- Extended frequency range reaching up to 5 kHz with V/oct CV, enabling use as four voltage-controlled oscillators at audio rates.994

| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (8) | |||
| CH1 FRQ/PH/RTO CV | cv | -10V to 10V | CV input for channel 1 controlling frequency, phase, or frequency ratio depending on the current mode; adds to the corresponding slider value.994 |
| CH1 RESET/SYNC | trigger | 0V to 5V | Per-channel input that resets or syncs the channel's oscillator phase/frequency when a rising edge is detected; function depends on reset vs. sync mode.994 |
| CH2 FRQ/PH/RTO CV | cv | -10V to 10V | 994 |
| CH2 RESET/SYNC | trigger | — | 994 |
| CH3 FRQ/PH/RTO CV | cv | -10V to 10V | 994 |
| CH3 RESET/SYNC | trigger | — | 994 |
| CH4 FRQ/PH/RTO CV | cv | -10V to 10V | 994 |
| CH4 RESET/SYNC | trigger | — | 994 |
| Outputs (12) | |||
| CH1 ASGN | cv | -5V to 5V | Assignable waveform output; waveform is selected via the wave button (triangle, downward saw, upward saw, trapezoid, step-random, or smooth random).994 |
| CH1 RECT | cv | -5V to 5V | 994 |
| CH1 SINE | cv | -5V to 5V | 994 |
| CH2 ASGN | cv | -5V to 5V | 994 |
| CH2 RECT | cv | -5V to 5V | 994 |
| CH2 SINE | cv | -5V to 5V | 994 |
| CH3 ASGN | cv | -5V to 5V | 994 |
| CH3 RECT | cv | -5V to 5V | 994 |
| CH3 SINE | cv | -5V to 5V | 994 |
| CH4 ASGN | cv | -5V to 5V | 994 |
| CH4 RECT | cv | -5V to 5V | 994 |
| CH4 SINE | cv | -5V to 5V | 994 |
Parameters 6
| Name | Type | Range | Behavior |
|---|---|---|---|
| CH1 Frequency Slider | fader | 0.01Hz – 100Hz | Controls channel a's oscillator frequency; in free mode sets frequency directly; in phase mode still sets frequency while other sliders set phase offsets.994 |
| CH2 Slider | fader | — | Controls channel b's frequency, phase shift, division factor, or multiplication ratio depending on the current global mode.994 |
| CH3 Slider | fader | — | Controls channel c's frequency, phase shift, division factor, or multiplication ratio depending on the current global mode.994 |
| CH4 Slider | fader | — | Controls channel d's frequency, phase shift, division factor, or multiplication ratio depending on the current global mode.994 |
| Mode Button | button | — | Cycles through free, phase, divide, and mult modes; the mode LED color indicates the active mode.994 |
| Wave Button | button | — | Selects the waveform for all ASGN outputs: triangle, downward saw, upward saw, trapezoid, step-random, or smooth random; the wave LED color confirms the selection.994 |
