Solfeggio Tone Harmoniser

Mix individual sine tones with vertical faders, build a selected three-tone harmony, or let the randomiser choose a new trio every 30 seconds while gently moving each active volume between 10% and 50%. This is intended for relaxation purposes only.

Three-tone harmony

Randomise always plays three different tones. It changes the trio every 30 seconds, crossfades gently for 7 seconds, and slowly moves active faders between 10% and 50% only.

Playback

Every oscillator is permanently set to a sine wave. Use the individual channel buttons for manual mixing.
