ER-101: Indexed Quad Sequencer
for Eurorack Modular Synthesizers
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 Also comes in 3 flavors to match your taste! See panel options here. Specifications
