Orthogonal Devices - ER-101 (Nostalgia)


We will not be getting this unit anymore because OD has stopped reselling to dealers. Please buy directly.

Unique and pretty complex digtal real-time sequencer with four tracks and memory. It makes it possible to compose sequences with thousands of steps with variable duration, variable gate length, arbitrary scales. Smooth tempo-matched transitions; mathematical functions per step; copy/paste; note repeat (ratchet) and shuffle per step. New firmware can be easily loaded via USB and the module can be expanded.

Nostalgia version with white print on dark grey powder coated faceplate.
