Imho this is yet the first virtual synthesizer that successfully mimics the behaviour of those old modular systems. It bears lots of secrets within certain knob ranges i wasn’t yet able to fully explore. I’m very happy that i was able to contribute to the development – Mike, you’re a hero! My alltime top fav synth and much more than the boned up 303 it may appear to be.

In Performance
ASM is mainly designed to be used as monophonic sequenced type of instrument. However it can be played polyphonically, or polyphonically sequenced. The instrument comes with a variety of patches: sequenced, polyphonic, monophonic, fx, etc.
CV Routing
Most modules send or accept control voltage (CV) which means the signal path can be modified in real time without any glitches in the audio. Sequencer has CV Gate/Note output and can be used when playing ASM in Note mode, monophonic- or polyphonically.

AUX signal processing
ASM can process external signals, for example through its filter. The AUX envelope follower outputs CV which allows you to patch up interesting effects. Even limiting and compression type of effects can be achieved.

Excellent VCF
The instrument contains an excellent self oscillating filter with tracking and filter modulation from oscillators, and has a 22kHz range (at 44.1kHz sampling rate).

Tight Envelopes
The envelopes are extremely snappy and evaluated every sample, no approximations here.
