Alesis Micron

The Alesis Micron, a new compact synth with the ION analog-modeling sound engine! The Alesis Micron is a powerful 8-voice Analog Modeling synthesizer based on the award-winning sound engine of the larger Alesis Ion in a compact 3.

Offering a virtually limitless sonic palette, the Alesis MICRON eight-voice analog-modeling synthesizer produces a big sound despite its small size. Whether you use a synth to accompany you on stage or in the studio or you prefer to work with the hundreds of preset Alesis sounds or create your own, the MICRON is a great musical companion.

The MICRON may be small in size, but it produces a big sound.

It offers 8 voices, each with 3 oscillators, 2 multimode filters, 3 envelope generators, 2 LFOs, sample and hold, and tracking generator.

The MICRON has two multi-mode filters, three envelope generators, and two LFOs: the full spectrum of synthesis components for shaping and creating sonorities and textures. For stage and studio-ready quality, the MICRON has 24-bit audio outputs and inputs via balanced connections.

Each of the MICRON’s voices contains two filters, and each filter can be one of the following different types, each with its own character and sonic flavor: Bypass, Low Pass: ob 2-pole, tb 3-pole, mg 4-pole, rp 4-pole, jp 4-pole, al 8-pole; Band Pass: ob 2-pole, al 6-pole, octave dual, band limit; High Pass: ob 2-pole, op 4-pole; three Vocal Formants, four Comb Filters, Phase Warp, Frequency, Resonance, Key Tracking, Envelope Amount, Offset, and Absolute.
