Yamaha TX802 Editor and Librarian

Voice editing — Every FM parameter on screen: all six operators with knobs for envelopes, levels, scaling and frequency, the LFO, pitch envelope, and the full 32-algorithm chart drawn exactly as Yamaha's. Plus the DX7II-era extras — poly mode, portamento, pitch-bend step and the complete controller matrix.

Edit live and hear every change as you turn a knob.

Performance editing — Set up all eight tone generators in one grid: voice, MIDI channel, output, detune, note limits, tuning and more. Factory Preset A and B voices show by name, and linked tone generators resolve just like the module's own display. Librarian — Read, save and reload all 64 voices and all 64 performances as standard .syx files. Double-click any voice or performance to load and play it instantly.

Every write to the module is verified and read back, with a clear warning if memory protect blocks it.

Also — Full SysEx monitor, drag-and-drop file loading, remembered MIDI ports, and built-in help on every control.

It runs in a web browser (Chrome or Edge — not Firefox or Safari) with a MIDI interface connected to the synth. It works on PC and Mac, and under Linux.

It's my personal tool shared for anyone who wants it. Setup instructions come in a short readme with the file, but I offer no support on this. It's shared "as is".
