Indexed quad sequencer

The ER-101 is a real-time composition, sequencing and automation environment, all in 26HP. It enables you to compose sequences of thousands of steps with variable duration, variable gate length, arbitrary scales, smooth transitions, save/recall device state and much more.

Highlights

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
configure each track to output gates or triggers
configure each track to have its own clock multiplier (1x to 99x)
CVs are chosen (indexed) from voltage tables of which there are 2 per track (A & B)
8 built-in and 8 user reference voltage tables for initializing the track tables
voltage tables are user-editable and have 100 entries per table
voltages between 0.000-8.192V at 2mV increments can be dialed in
each voltage table can be configured to use note display or numeric display
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 you to edit-and-commit on the beat 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.
note repeat (aka ratchet) any step
shuffle (aka swing) any step
expansion port
last saved snapshot is loaded automatically on power-up
firmware upgradeable via USB
expander available: ER-102
