Brian Clarkson of Orthogonal Devices let us know about their ER-101: Indexed Quad Sequencer, ‘a new kind of Eurorack sequencer.’

Clarkson calls the ER-101 ‘a real-time composition, sequencing, and automation environment”. It lets you create sequences of thousands of steps, with variable duration, variable gate length, arbitrary scales, smooth transitions, save/recall device state and more.

Here’s a demo of the ER-101 in action:

Features:

4-track sequencer

stepped and smooth voltage transitions

each track has 3 outputs: 2 CVs + 1 gate

each track has its own adjustable loop points

each track contains up to 100 patterns and each pattern can contain up to 100 steps

each step can be individually adjusted to have 0-99 clock cycles in duration

each gate can be individually adjusted to have 0-99 clock cycles in duration with or without ratcheting

CVs are chosen (indexed) from voltage tables of which there are 2 per track (A & B)

built-in voltage tables: 12-tone equal tempered, 22 shrutis, linear 0-8V, exponential 0-8V, linear-exponential 0-8V and others

voltage tables are user-editable and have 100 entries per table

voltages between 0.000-8.192V at 2mV increments can be dialed in

smoothing can be enabled for individual steps, entire patterns and/or entire tracks

smoothed transitions are NOT simply slews but are adjusted to match the current tempo in real-time

hold feature (complete double-buffering of device state) allows smooth musical edit-commit-at-will while the sequencer is running

while in hold mode, committing changes to a running sequence can be either immediate or quantized to the beat

reset can be either immediate or quantized to coincide to with the ending of the current track, pattern, or step

stores up to 16 snapshots of the state of the entire device

arbitrary insert/delete of patterns/steps with clipboard style copy/paste

math button allows you to specify a mathematical operation to apply to a step, a pattern or a track.
