Alesis Micron Synthesizer I am selling it because I am getting a new piano keyboard, and don't need the extra sounds the Micron has to offer, (trust me...there are LOADS!) Comes complete with manual. More info: The virtually limitless sonic palette. The micron is an eight-voice analog-modeling synthesizer. Despite its small size, you'll be impressed with the micron's big sound. Whether you use a synth to accompany you on stage or in the studio, and whether you prefer to work with the hundreds of preset Alesis sounds or create your own, the micron is the perfect companion. The micron also contains a powerful sequencing section with phrase, step, and drum sequencing, an arpeggiator, and stereo effects. SYNTHESIS 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.
