Alesis Micron (2004)
Analog Modeling Synth

 

Portable virtual analog modeling synthesizer with opened synthesis system-

Acompact version of the famous Alesis ION, a complex, digital, cold and fascinating machine.

edit interface
micron

info KEYBOARD 37 velocity keys. Main panel features a display, 4 knobs, 12 buttons, an encoder, a pitch wheel and 2 assignable modulation sliders.

Rear panel terminal connectors:
- Midi interface
- headphones
- main out signal
- extermaò signal line input
- damper pedal input
- expression pedal input.

ac Power supply
is an external PSU 9VAC-AC 1.5A (NOT DC!).


 

edit VOICE the Coldfire processor manages 8 voices polyphony.
A voice is composed by 3 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 emulates the transistor VCO temperature drift.


structure

 

edit OSCILLATOR main synthesis system is based on 3 digital oscillators plus a pink / white noise.
The oscillators feature 3 waveforms:
- triangle / sawtooth
- sinewave
- pulse with variable width
Special waveshape smooths progressively a wave to pure sinewave.


osc


 

edit SYNC OSC harmonic contents can be altered by 4 processes:
- FM frequency modulation: an oscillator controls the frequency of another with variable depth. The FM offers 6 presets models (3 linear + 3 exponential)
- ringmodulator is quite standard with variable depth
- hardsynch: master osc restarts the period of the slave one following 2 modes (refer to table)
- softsync: blends more smoothly the harmonics, also 2 different pathmodes (refer to table).


Mode Routing1 Routing2
hardsynch osc 2 -> osc 1 + osc 2 osc 3 -> osc 1 + osc 2
softsync osc 2 - > osc 1 osc 2 + osc 3 -> osc 1




edit PERFORMANCE
these are the "setups" with several playmode features:
- 2 split zones
- octave shift
- patterns: are looped sequences or arpeggios (see below)
- rhythms programmed drum loops
- 3 curves playmode: linear, exponential and logarithmic

edit
FILTER 2 multimode indipendent resonant digital filters at 2/3/4/6/8 poles.
They can be chained in any order in parallel or series, and special prefilter function defines the amount of sources send to the filters. There are 21 filter models including standard classic like 2/4 lowpass and special ones like formant or special resonance. FULL filter LIST

 

filter




edit ENVELOPE 3 EGs for each oscillator:
- EG1 amplitude
- EG2 filter
- EG3 pitch / AUX modulation (assignable).
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


 


edit
LFO each OSC features bipolar 2 modulators (0,010 – 1000 Hz) with same specs:
- frequency sync with tempo dividers to patterns or Midi clock
- note retrigger
- natural desync
- sample & hold mode with lag smooth
LFO features 4 shapes:
- triangle + 90 degrees phase shifted variation
- saw + 90 degrees phase shifted variation
- sine + 90 degrees phase shifted variation
- square + 90 degrees phase shifted variation.
TRACKING GENERATOR a special 12 / 16 step grid can be drawn to define a special motion for 38 parameters for special moving texture effects.


LFo


 

edit MATRIX modulation is really completed, here's roughly the possible routings:


SOURCES: DESTINATIONS:
- LFO waveforms
- aftertouch
- EG1-2-3
- assignable sliders
- wheels
- velocity
- MIDI CC#
- random
- expression pedal
- portamento level
- sample & hold


pitch osc1-2-3
- pitch whole/individual with limited octave range
- amplitude
- osc waveshape
- FM amount
- ringmodulation / noise amount
- portamento
- filter
- pan
- EG
- LFO
- sample & hold



edit SEQUENCER patterns can be recorded in 2 manners:
- real-time mode (records also knobs movements)
- step by step.
Some classic edit functions: velocity edit, duration change, move note, cancel...
The 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.


sequencer

 

 

edit 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.

micron



edit EFFECT 3 DSP sections:
- FX1: chorus, flanger, phaser and a 40-band vocoder (seems derived from Alesis Metavox effect)
- FX2: delay (mono or stereo) and reverb (plate, room and hall).
- boost: FX1 + FX2 outputs can be boosted by distortion, overdrive, fuzz and compressor



edit MEMORY:
- 500 ROM presets
- 500 RAM patches slots
- 200 rhythm patterns.

EDITOR there are some computer-based editors:
- hypersynth: complete but commercial (LINK)
- ctrlr editor: free but lacks matrix control (LINK)

comment


REVIEW: "complicated machine, sound is for sure interesting and rich. Synthesis routing system is quite impressive - edit interface and tiny keyboards are awkward- a LOT of power, trapped in this unworthy silver box. A too soon forgotten machine."

 
"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"
from Micron Manual (by modest guys at Alesis group)
