ABL Pro 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.

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 ABL Pro in Note mode, monophonic- or polyphonically.

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

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).

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

Key features:
- 2 (+1) Oscillators with sawtooth, squarewave, pulse, triangle and sinus waveforms
- Sync and ring modulation between oscillators
- Noise generator with variable color
- 2 ADSR envelopes
- Full range oscillators with no aliasing
- Non-linear filter with self oscillation and VCF tracking
- Modulation generator with audio rate frequency (can be used as third oscillator)
- Can be used to process external signals, for example through the VCF
- Stereo Delay unit with modulatable delay time (left & right)
- 32-voice polyphonic mode
- Patch cable system allows additional CV routing
- 500+ preset patches and sequences
