Alesis Andromeda A6

Alesis Andromeda A6 (Red) Image

The Andromeda A6 is a true 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! 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 onboard is an extensive mod matrix for enormous freedom in configuring Andromeda's sounds!

No analog synth would be complete without a set of classic effects and features. Andromeda also offers Portamento with nine slopes and legato functions. A built-in arpeggiator and analog-style sequencer are available, with MIDI sync! There are also some high quality digital effects such as reverbs, chorus, echo, distortion and more! Andromeda comes with 256 breathtaking preset patches plus 128 user. A PCMCIA-format memory card slot allows for additional programs and mixes. Andromeda is pure analog bliss, with all the features, stability and widgets of modern digital synths. It has been used by BT, Air, Duran Duran, Depeche Mode, Nine Inch Nails, DJ Tiesto, Klaus Schulze, Yes and the Pet Shop Boys.

Maybe the most epxressive synth manufactured at the 21th century, only minus is.. if it would sound little bit warmer, like those 30 years ago produced polys korgs, oberheims, yamahas etc. there wouldnt be anything that could touch this monster. Can anyone explain technically why is andromeda kind of "colder"?

this synth is ridiculous. its like having a polyphonic voyager melded together with an oberheim ob-8, a access virus, & a drum machine all in one.....and more...I've only had it for 5 days, but.....look, my lady's been hearing it in other parts of the apt & she calls it the millenium falcon!!! Serious wall shaking tones, very expressive strings, awesome leads, extensive envelope implementation, freely assignable controllers and mod's spooky man, got a real sneaky factor goin on that chuckles "hehehehe, yes i am an alesis, bad as hell & iller than you can imagine....."

Just wanted you to know that there are some very nice new Alesis Andromeda sound demos to be heard at

I think these demos are the first ones that really show the Andromeda's huge potential in capable sound designers hands. Don't let the vast modulation options to overwhelm you when programming the Andy. There is a wealth of hauntingly beautiful sounds awaiting for your discovery under the Andromeda's hood. Too bad its discontinued. We will miss you Andy..

Glad to hear you got 2-3 years from your Alesis gear Matt. That's 2-3 years more than I got from my Polymoog. In a way you have to forgive it - nothing ventured, nothing gained. I love my Polymoog, my Voyager AND my Andromeda. If I bought with my head rather then my heart, I'd have none of them. I'm pretty sure you feel the same ! ;-)
