Yamaha DX7

“This is a Yamaha DX7 digital programmable FM synthesizer from the mid-1980s with memory cartridges in working condition.

This listing includes the read-only memory cartridges numbered 3 and 4, which contain the “master group”, “keyboard and plucked group”, “orchestral and percussive group”, and the “complex & effects group. These cartridges are tested with this synth and work.

This listing also includes a read-write memory cartridge for you to store your own DX7 patches. This is also tested and works.

The internal memory works too and includes the default set of sounds. However, the internal battery is low and needs to be replaced. If this internal battery dies, you will need to reprogram the internal memory, which can be done using free software like SysEx Librarian and the original soundbanks available from Bobby Blues website. Search the web for “Yamaha DX7 factory reset | Load preset sounds sysex” for instructions. If you can program this synth, you can easily learn how to reprogram the internal memory.

The wheels, buttons, and keys work fine. All the inputs and outputs work: headphones, main output, sustain pedal, MIDI, etc.

This was a working instrument for many years and it was used in smokey rooms in the 1980s and 1990s. This instrument is dirty! It has not been used in a smoking environment for about 15 years and it does not smell like smoke anymore.” Click here to visit listing on eBay
