Yamaha TX802 Editor & Librarian — browser-based, no install
Get the editor for free in my web shop here: espenkraft.com/b/MnPYo
A single HTML file that turns any Chrome or Edge browser into a full editor and librarian for the Yamaha TX802. Connect over MIDI and take control of the whole machine.
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.
*fractional scaling and micro tuning is not implemented in this editor.
*this is NOT fully compatible with the DX7II except for some voice editing
Made as a personal tool. Shared as is. I offer no support for this.
