Synth Lab
Build sounds from scratch with an analog-style synthesizer — oscillators, filters, envelopes — and watch the waveform and spectrum change. Freeze a tone to see its harmonics. A simpler Junior version is just right for grades 2–4.
Patch Lab
A build-it-yourself modular synth. Wire real modules — oscillator, filter, envelope, LFO — together with patch cables and the sound follows your wiring. Add modules, rearrange the rack, and play it with the keys or a MIDI controller.
Launch ToolImage Synth
Turn a picture into sound. Paint on a grid — or drop in a photo — where left-to-right is time, up is pitch, and brighter is louder. Hear what a shape sounds like, then save it as a WAV.
Launch ToolSound Manual
The science behind the synths — pitch, loudness, waveforms, harmonics, envelopes, filters, and a little music theory — with diagrams you can hear. A self-study guide to how sound works.
