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.

I never clicked with it. At first, I was very impressed with the vast programming possibilites, but slowly realised that it just never sounded as good as I hoped. Sold it off a bit too cheap.

The A6 can do a lot of things reasonably and can do pretty much anything an analog is supposed to do at a passable level but there is one thing that that it excels at...polyphonic unison. When in 4 voice unison you have 4 note polyphony and 8 oscs per voice. The sound of the A6's unison chords are distinctly different from VA unison chords and it is the only analog with enough voices to pull it off. A prophet 12 can sound similar if the filter cutoff is remain low (below 1500hz or third harmonic of the tonic, whichever is lower) but the A6 remains dominant here.

-- Also.. make sure all of the cables inside the synth are seated well.

It's hard to guess what the problem might be. If it only hangs when a patch is selected I suppose it could have something to do with the onboard memory. There are two MPUs. One runs the display and reads switches and the other is the synth engine and pot reader. Perhaps reinstalling the OS on the synth and refreshing all the programs might be a start. It could also be a faulty IC, like the FX IC, not responding to the MPU. Narrow it down if you can. I don't know what spare parts are available so it is hard to guess if it is repairable.
