The Alesis Andromeda is a 16-voice, 16-channel multitimbral analog synth with all the controls you need to creatively shape its mind-blowing sonics. The fully analog signal path is controlled by a high-speed Motorola Coldfire microprocessor, and has 2 analog oscillators and 2 filters per voice. Available waveforms are sine, triangle, square, up saw, and down saw. External audio inputs allow routing of outside signals through its filters. Also features 3 - 7-stage, 3-level envelopes capable of functions never before found in any analog synth. An extensive mod matrix offers enormous freedom in configuring, while its front panel gives you 72 knobs and 144 buttons for rapid-fire sound tweaking. The 61-note, synth-weighted keyboard features velocity and aftertouch sensitivity. Performance features include portamento with 9 slopes, legato functions, an arpeggiator and analog sequencer with MIDI sync, high-quality digital effects, and a nasty analog distortion circuit. Internal program memory on this Alesis keyboard features 256 presets and 128 user-defined sets, plus a PCMCIA-format memory card slot for additional programs and mixes.
