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.

Fantastic sounding synth.
It is already modern classic.

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 ! ;-)

Just for balance and clarity, from Gordon Reid's review in April 2001 Sound On Sound magazine: "Huge chunks of its architecture are digital, ... the controllers in the sound-generation system — the envelopes, the LFOs, and the Sample & Hold — are all digital, as is the oscillator tuning (although not the oscillators themselves). This makes the Andromeda a hybrid analogue/digital synth, much like, for example, the Sequential Prophet T8." This isn't an extremely prettied up Moog. It's the best of the old and the new.

I have owned many analogue synths over the past 10 years(minimoog d, arp odyssey, octave cat, sequential pro one, jupiter 8, mks80, prophet 5, voyager, DSI poly evolver and more). The andromeda has been the only synth I have kept hold of over this time. If you are prepared to dig into it and programme you will hit pay dirt. It can sound pretty close to many of the other synths I have owned if that's what you want; providing you programme it carefully and the modern feature set is essential for me. I have never had a problem with it despite frequent use for many years.
