Though it's digital, the Alesis Micron has the heart of an analog synthesizer, and is made to emulate the voicing of an analog synth. Three oscillators with eight voices per oscillator, along with two filters, three envelope generators, two LFOs, and more give you tons of programmability and potential to shape your sound in an impressively compact 37-key synth. Taking cues from the Alesis Ion, the Micron gives you portability along with powerful analog modeling.
