Batumi
Fully voltage-controlled quadruple digital low frequency oscillator with four identical channels, free/quadrature/phase/divide sync modes, assignable waveform outputs, zoom mode for precise frequency setting, and reverse power protection.731
Capabilities 1
- LFOlfo
- Four independent voltage-controlled digital LFO channels with sine, square, and assignable waveform outputs. Free, quadrature, phase, and divide sync modes. Frequency range from ~28 hours to 500Hz.731
Jacks 20 — 8 in / 12 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (8) | |||
| CH1 frq/ph/div | cv | -5V to 5V | 731 |
| CH1 reset/sync | trigger | — | User-defined trigger input; functions as cycle reset or external tempo sync depending on jumper setting.731 |
| CH2 frq/ph/div | cv | -5V to 5V | 731 |
| CH2 reset/sync | trigger | — | In synced modes: holds (pauses) all LFOs when triggered.731 |
| CH3 frq/ph/div | cv | -5V to 5V | 731 |
| CH3 reset/sync | trigger | — | In synced modes: reverses the direction of the waveform when triggered.731 |
| CH4 frq/ph/div | cv | -5V to 5V | 731 |
| CH4 reset/sync | trigger | — | In synced modes: selects the next assignable waveform when triggered.731 |

Parameters 6
| Name | Type | Range | Behavior |
|---|---|---|---|
| CH1 Slider | fader | 0.01Hz – 100Hz | In free mode, sets the channel's own frequency (0.01Hz–100Hz). In quad mode (sliders 2–4), controls amplitude. In phase mode (sliders 2–4), sets phase shift. In divide mode (sliders 2–4), sets the division ratio. Slider 1 acts as master frequency in non-free modes.731 |
| CH2 Slider | fader | — | 731 |
| CH3 Slider | fader | — | 731 |
| CH4 Slider | fader | — | 731 |
| LFO Sync Mode | button | — | Central button cycles through FREE, QUADRATURE, PHASE, and DIVIDE modes. Each mode is indicated by a dedicated LED. Hold for one second to enter zoom mode.731 |
| Reset/Sync Mode Jumper | jumper | — | No jumper = reset mode (trigger resets LFO cycle). Jumper present = sync mode (LFO frequency slaves to external clock or tap tempo).731 |
