The ER-101 is a 26HP real-time composition, sequencing and automation environment for eurorack. Compose sequences of thousands of steps with variable duration, variable gate length, arbitrary scales, smooth transitions, save/recall device state and much more, especially with the included ER-102 expander.
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 initialising 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
ER-102
- up to 99 parts (each with its own reset step and looped section) per snapshot
- part selection/activation is under CV/gate control
- various part transition behaviours
- up to 16 groups of steps per snapshot
- perform operations on groups of steps
- assign steps to groups with Euclidean masks
- route 3 channels of CV/gate modulation to steps via groups
- new invert and rotate operations
- step record (a.k.a. remote control)
- real-time record with pass-thru during rehearsing and recording
- alter record (a.k.a. real-time overdub)
- essentially infinite storage via uSD card
- firmware upgradeable via uSD card
Includes Eowave case, Konstant Lab PWR Checker, and UK power supply + adapter.
