Delta6 is a 6-operator FM synthesizer built around a fully open modulation matrix.
Instead of forcing you to choose from a fixed list of algorithms, Delta6 lets you freely route operators and visually see how modulation flows through your patch.
Features:
- Route operators freely through the modulation matrix, letting you create any FM structure and experiment with your own signal paths.
- Build complex sounds with 6 FM operators, each with its own tuning, level, waveform, and ADSR envelope.
- Go beyond traditional FM with five operator waveforms: Sine, Triangle, Saw, Square, and Noise.
- Push Operator 6 further with its feedback control.
- Add subtle analog-style pitch variations with Drift, allowing for a warmer and more organic sound.
- Give your sounds space with the built-in Reverb, with adjustable reverb size and mix.
- Add width and character with the built-in Chorus effect, inspired by classic hardware chorus circuits.
- Use velocity sensitivity to make your patches respond dynamically to how hard you play.
- Play up to 16 voices of polyphony, or switch to Monophonic mode with Legato for expressive basses and leads.
- Use the dice button to instantly generate random presets.
- Use the preset browser to quickly find new sounds, or save and load your own custom presets!
