Isla Electronics ASYX v1.28 is a software emulation of the Alesis Andromeda A6 synthesizer for Windows.
It delivers a detailed signal flow with controls for exploring. Start simple, then drill down as your sound demands.
Signal Flow
ASYX Oscillators
Simulates the operation of specialized A6 ASIC oscillators, whose analog design was developed based on the Moog 921B. Two oscillators per voice provide simultaneous signal generation, pulse width control, sub-oscillator operation, hard and soft sync, and frequency modulation. Noise and ring modulation are fed to a mixer with a pre-filter.
Dual Filters
ASYX uses A6 ASIC filters: a 12 dB per octave multi-mode filter based on the Oberheim SEM, and a 24 dB per octave low-pass filter based on the Moog 904A. Low-pass, high-pass, band-pass, and notch filters are available in series or parallel routing with separate pre and post filter mixing.
Envelope Generator
Three envelope generators with six waveforms and individual controls for frequency, amplitude, offset, initial phase, duty cycle, and polarity. Delay, trigger, and clock sync settings are available for each envelope generator.
Multi-Stage Envelopes
Three seven-stage envelopes with delay, attack, two decays, sustain, and two releases. Nine customizable curves for each attack, decay, and release stage with adjustable mid-levels. Additional controls include loop, trigger and repeat trigger, velocity sensitivity, key tracking, and smoothing.
Deep Modulation
Modulation routing with independent controls for source, destination, amount, offset, and on. Sources include envelopes, LFOs, sample and hold, tracking generator, MIDI, and performance controllers. Destinations include envelope time, oscillator, filter, and effects parameters.
Sequencer and Arpeggiator
A 16-step sequencer with per-note controls, velocity, gate, and rest, as well as an arpeggiator with its own grid and tuning controls. Sequencer and arpeggiator settings are saved for each program.
Effects
29 digital effects algorithms including chorus, delay, reverb, and combined configurations. Algorithm parameters and effect settings are saved for each program.
Analog Character
Independent depth adjustments for oscillator settings, tracking and pulse width, filter cutoff frequency and resonance, envelope sync, voice levels, overall drift, and oscillator drift. The main analog knob scales the combined variation.
Mixer Mode
Up to 16 parts per plugin instance for multitimbral operation, keyboard splitting, and layering. Each part has its own program, MIDI channel, key range, level, and output route.
Patch Management
Over 1,200 built-in programs with original factory sounds and artist banks. Search by title, author, or bank, filter by category, and save favorites.
Hardware Integration
Thanks to bidirectional MIDI connectivity, the A6 knobs and buttons can control ASYX. Enable real-time parameter sending so that changes made in ASYX are transmitted to the hardware.
Import original A6 SysEx programs and banks into the library or send the current program, including unsaved changes, to the selected hardware slot. Store large banks in ASYX format and prepare a bank in 128 A6 program format when you need to transfer it to a hardware device.
About the Alesis Andromeda A6
The Alesis Andromeda A6 combined sixteen analog tones, dual filters, and extensive modulation capabilities. Working examples are becoming increasingly difficult to find, and rising used prices are putting them out of reach for many musicians. Maintenance is also becoming increasingly difficult due to specialized ASIC chips and unavailable spare parts.
ASYX was developed to make this instrument accessible as software. Working directly with the original A6 synthesizer, its performance was measured, compared, and refined while maintaining compatibility with the original patches.
