Expert Sleepers - '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.
