Alesis Micron

Industry-leading analog-modeling sound engine in a lightweight and portable keyboard

The Micron boasts the same sound engine as the acclaimed Alesis Ion in a compact 3-octave keyboard, offering breakthrough analog realism, high-resolution control, and tremendous value. The Micron is compatible with Ion programs and holds over 1,000 programs and multitimbral setups.

The Micron offers continuously variable wave shapes, plus sync and FM synthesis. 20 filter types are included, along with 2 LFOs with multiple wave shapes and sample & hold. The Micron has 8-voice polyphony with 3 oscillators per voice, and is 32-part multitimbral. In addition to a powerful modulation matrix, the Micron offers a programmable step sequencer, arpeggiator, rhythm sequencer for drum kits, and dynamic realtime phrase sequencer—all of which sync to MIDI clock.

Effects include a 40 band vocoder that does not use up any polyphony, 4 drive effects, and stereo bus effects, including reverb. For assignable realtime control, the Micron offers 3 knobs, 2 modulations sliders, and a pitch wheel.
