Yamaha DX7 II sysex
Sound patches
This page contains downloadable voice and performance data as .sysex files. A sysex is a binary file that stores a sequence of system exclusive MIDI information mirroring the memory of the device: to transfer it you need to hook your Yamaha DX7 II-FD or II-D to a computer via a MIDI connection, then use one of the many sysex managers available for both Windows and MacOS to transfer each bank over. Voices from the Yamaha DX7 sysex patches are also compatible.
