Expert Sleepers Otterley Multi-LFO Module
'Otterley' is a multi-LFO module, designed to offer extensive modulation possibilities, with a good amount of control and flexibility, while remaining nicely compact.
Four of the outputs are switchable between sine and square LFOs. Their frequencies are jointly set by the Speed and Spread knobs, which control the base speed and the speed difference between the outputs, respectively. Both controls also have CV inputs. These four outputs can also be switched between bipolar (±5V) and unipolar (10V positive or negative), and can be reset to the start of their cycle via the Reset input.
A fifth output offers another, independent, sine LFO with its own speed knob.
The module is 100% analogue.
Key Features:
- Provides a 100% analogue signal path for classic modulation textures.
- Features a compact design that offers extensive modulation while saving rack space.
- Includes four primary outputs that are switchable between sine and square waveforms.
- Uses Speed and Spread knobs to jointly manage base frequency and the speed relationship between outputs.
- Offers CV inputs for both Speed and Spread to allow for external dynamic control.
- Allows the four main outputs to be switched between bipolar (±5V) and unipolar (10V positive or negative) operation.
- Features a Reset input to restart the LFO cycles of the four primary outputs simultaneously.
- Includes a fifth independent sine LFO output with its own dedicated speed control for additional layering.
