Added

What the original never had.

Each one off at first. Switch on what you need.

Poly
8voices

Each voice a full copy of the circuit: oscillator, filter, amplifier, envelope.

The MONO · POLY switch set to POLY
The MONO · STEREO · BINAURAL switch set to BINAURAL
Stereo · Binaural

Wider than one machine.

STEREO spreads the notes. BINAURAL plays each one twice, hard left and right.

KEY TRACK switch on II
Key track

I · II

The filter follows the keys. II tunes self-oscillation to the semitone.

EG loop

The envelope, on repeat.

While a key is down, it restarts from the attack.

Audio rate LFO
2kHz

The LFO from 20 Hz up to 2 kHz, for FM-style tones.

23 factory presets for Mk I and Mk II, plus your own.

Against the original

Questions

Why two models?

The 1984 version has a different filter: 24 dB per octave instead of 12, with resonance on a slider. MODEL switches between them, even on a held note.

Does it run on a Mac?

Yes. VST3, AU and standalone, for Apple Silicon and Intel Macs. On Windows, VST3 and standalone.

Can I use a breath controller?

Yes. Anything that sends MIDI CC 2 drives BREATH VCF and BREATH VCA, the way the original mouthpiece did.

What does the demo do?

Everything the full version does. After two minutes of sound, a burst of hiss plays about every 30 seconds. Activate a licence key in the plug-in and it stops.

Why is there hiss when I play?

The original had a noise floor you can hear, so the plug-in starts with it. A switch under the MODEL lid turns it off.

How long does the launch price last?
