For sale: Alesis Micron analog modeling synthesizer in excellent condition for its age. This unit has a new volume pot installed and has been completely disassembled, cleaned, and reassembled. It is not perfect cosmetically but is far better than average considering how rough most of these are by now. The red volume knob shows some degradation (see photo 14), which is common, and the white encoder knob has a slightly tacky feel. Everything functions as intended. The only functional issue noted is that very occasionally the octave up button may require a second tap.
Be sure to examine all photos carefully, as we've done our best to document the condition. Of note, there are a few blemishes in the finish (see photos 16-18), some minor markings on the red side panels (see photos 5 and 9), and a slight misalignment of a few keys, which is common on these models and does not affect usability (see photo 11).
The Micron is a compact virtual-analog synthesizer based on the same synthesis engine as the Alesis Ion. It offers deep subtractive synthesis with multiple oscillators per voice, dual multimode filters, extensive modulation routing, and a full suite of onboard effects. Despite its small size, it is capable of complex sound design, layered and split setups, and performance-oriented programming via macros, arpeggiator, and sequencer. The Micron remains a powerful and flexible instrument for basses, leads, pads, and evolving textures, particularly for users who value depth over panel space.
