“Yamaha TX7 Tone Generator FM Expander Sound Module.
Works well. About 30 years old. Home studio use.
Has sounds loaded and will work as-is. But… Requires midi software connection, or DX7 connection, to program and change sounds.
Not multitimbral. Plays one sound at a time.
Desktop unit. Non-rack-mountable unless you have a rack tray. 10 ft power cord.
Display is not backlit. These units, like the original DX7, require modification for backlit display.
Manual (photocopy) included.” Click here to visit listing on eBay
