Six Sines is a six operator audio rate modulation synth. It contains features from classic FM and PM synths. If you love the DX7 but found programming it too easy, Six Sines might be for you?
The key features are
- 6 operators which can self-modulate or modulate other operators, each with its own waveform
- A modulation system where each node in the matrix gets an LFO, an envelope, and so forth
- A wide variety of modulation mechanisms - Frequency modulation including exponential and linear/TZ, Amplitude (ring) modulation, and more.
In April of 2025, as Version 1.1 was shipping, the One Synth Challenge chose Six Sines as its synth of the month. You can hear the final playlist here:
