“YAMAHA TX7 FM Expander & Tone Generator, For DX7 Keyboard
I am selling this on behalf of a friend – I have tested its functionality as far as I can (I do not have a DX7 keyboard, but all of the preset sounds responded as they should to a generic keyboard on the MIDI input), and the function buttons all bring up the relevant function on the display.
The case is in good condition, with no cracks – there is one missing screw, as the internal plastic moulding that it screws into has broken off, but this does not affect the integrity of the case.” Click here to visit listing on eBay
