YAMAHA TX7 - FM synth, DX7 expander, "DX7-in-a-box"

via this auction

"Good working condition. Comes loaded with my favorite TX7/DX7 patches: from lush Brian Eno-style pads to organ sounds to crazy FM synth weirdness. The TX-7 is basically a desktop module version of the Yamaha DX-7 FM synthesizer."

Note you cannot fully edit it via the front panel. You need a DX7 or software editor.
