Alesis A6 Andromeda w/ Original Box

via this auction

"Alesis A6 Andromeda Keyboard Synthesizer. Shipped with UPS Ground. This is a brand new, still in box, unused synthesizer. I bought it to use in a band that never happened. It has been plugged in twice. When I fist bought it I plugged it in pushed a few buttons to see what they do, then boxed it up and put in the closet for 14 years. I plugged it in for the second time this morning and it works like its supposed to still.

The Andromeda A6 is a true real analog synthesizer using two analog oscillators per voice, sub-oscillators, hard and soft sync and more! It features 16-voice polyphony. With the Andromeda, you'll find a huge range of tonal possibilities: searing leads, warm pads, fat bass lines, extreme sound effects and more. And of course there are plenty of knobs (72) and buttons (144), even an assignable ribbon controller for addictive hands-on real-time control! The large high-resolution LCD display is excellent and shows you actual rather than relative values of parameters. Andromeda will integrate seamlessly into any studio with its total MIDI control and sync, individual voice outputs, stereo outputs and several audio inputs.

Andromeda is completely analog - no emulation! [note the oscillator tuning, envelopes, LFOs, and Sample & Hold are actually digital as well as the added effects] It features two analog filters per voice that sound great! They are a multimode 2-pole and a 4-pole lowpass. External audio can be routed through these filters too (three 1/4" jacks)! As for modulation, Andromeda has three LFOs, each with six waveforms and they can be synced to MIDI clock. And there are three 7-stage envelopes with very creative and flexible functions. Also on-board is an extensive mod matrix for enormous freedom in configuring Andromeda's sounds!"


  1. Do not write that Andromeda is 100% analog. The effects and envelopes are digital. These can be excluded from the signal path, but the keyboard is not 100% analog.
