TinySynth

TinySynth is a compact 4-operator FM synthesizer for macOS, made to help you explore FM without getting overwhelmed.

I built this for curious musicians, sound designers, and tinkerers who want to dive into FM synthesis without wrestling a spaceship of knobs. TinySynth keeps things simple, clean, and tweak-able.

🎛️ Features:

• 4 independent operators — adjust frequency, tuning mode, and envelopes
• Absolute + Relative tuning modes
• 5 built-in modulation algorithms
• ADSR envelope control and level triggers
• Clean interface focused on sound design, not menu-diving

TinySynth is a sketchpad for exploring sound, learning FM, and surprising yourself.

Try it out, mess around, and see what you make.
If you’ve got feedback, I’d love to hear it.
