longDescription = ''
The synth core supports:
- Arbitrary amounts of polyphony
- 8 operators
- No fixed "algorithms"
- Arbitrary modulation, every operator can modulate any other operator, even itself
- Arbitrary carrier selection, every operator can be a carrier
- Sine LFO, separate LFO per voice, modulates amplitude and frequency of operators
- Envelope per operator
- Carrier stereo panning
- Velocity sensitivity per operator
- Mod wheel sensitivity per operator
- Pitch bend
- Keyboard scaling
- Sustain, sustained keys can overlap each other for a very rich sound
- Full floating point implementation optimized for SIMD
- Hard real-time constraints
