VOICE Coldfire processor manages 8 voices polyphony. A voice is composed by 3 digital oscillators with individual settings:
- octave set + fine pitch tuning
- mix level + stereo panning position
- monophonic with portamento and glissando
- stacked voice option (up to 8 in unison mode) + analog drift which emulates a VCO temperature drift.
OSCILLATOR synthesis system is based on 3 digital oscillators plus a pink / white noise; a special waveshape smooths progressively a wave to pure sinewave.
The oscillators feature 3 waveforms:
- triangle / sawtooth
- sinewave
- pulse with variable width.
OSC harmonic contents can be altered by 4 processes:
PERFORMANCE these are the "setups" with several playmode features:
- 2 split zones
- octave shift
- patterns: special looped sequences or arpeggios
- rhythms programmed drum loops
- 3 curves playmode: linear, exponential and logarithmic
FILTER 2 multimode indipendent resonant digital filters at 2/3/4/6/8 poles. Up to 21 filter models including standard classic like 2/4 lowpass and special ones like formant or special resonance. Filters can be chained in any order in parallel or series, and special prefilter function defines the amount of sources send to the filters. FULL LIST
ENVELOPE Each EG is defined by a 4-segment ADSR plus some 2 extra parameters: attack and decay have different a linear or exponential initial shape and once an EG is engaged, the segments can be looped at definable points or retriggered from start or left in continous free flown mode.
EG1 amplitude / EG2 filter / EG3 pitch / AUX modulation (assignable).
LFO teach OSC features bipolar 2 modulators (frequency range: 0,010 – 1000 Hz) with same specs:
- triangle + 90 degrees phase shifted variation
- saw + 90 degrees phase shifted variation
- sine + 90 degrees phase shifted variation
- square + 90 degrees phase shifted variatio

SEQUENCER classic edit functions: velocity edit, duration change, move note, cancel (...) user patterns can be recorded in real-time or step by step. The special drum editor works in real-time or uses the special grid mode: 1/4, 1/2, 1, 2 or 4 bars and resolution at 8, 12, 14, 16, 20, 24, or 32 step per bar.
ARPEGGIATOR this functions includes 6 arpeggio motions: up, down, up and down, up + inclusive (pendulum mode), down + exclusive (does not play lowest and highest notes) and octave jump.
SYNC arpeggiator, drums editor and sequencer can be synched internally or by Midi clock. Tempo frequency can be set manually or defined by tap tempo.
EFFECTS 3 DSP sections:
- FX1: chorus, flanger, phaser and a 40-band vocoder (derived from Alesis Metavox effect)
- FX2: delay (mono or stereo) and reverb (plate, room and hall).
- FX3 boost: FX1 + FX2 outputs can be boosted by distortion, overdrive, fuzz and compressorMEMORY :
- 500 ROM presets
- 500 RAM patches slots
- 200 rhythm patterns.
- deep edit is painful
- lacks charm
- cheap now
- flexible synthesis
Akai Miniak - is a Micron repackaging with same engine, but different performance set and vocoder
Blue Limited edition same machine but different colors.
ALESIS Ion bigger with more real-time controls, but essentially the synthesis engine is the same, in fact machines are patch-compatible but FX section, rhythm and patterns

A memes from my collection :)"Our first product in the line was our A6 Andromeda, a true analog synth considered by many to be the most powerful non-modular analog synthesizer ever made. Next came the Alesis Ion, praised as one of the most powerful and best sounding Analog Modeling synthesizers ever"
