'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.


Otterley's specifications are as follows:
  • Panel width: 8HP
  • Module depth: 42mm
  • Current draw: 82mA on the +12V rail, 80mA on the -12V rail
  • Inputs:
    • CV inputs for speed (with attenuator) and spread
    • Gate input for reset
  • Outputs:
    • Four related sine/square outputs
    • One additional sine output
  • LFO speed range
    • 150 seconds/cycle to 75Hz (outputs 1-4)
    • 50 seconds/cycle to 50Hz (output 5)
