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
