Roland GM-70

Roland GM-70

The GM-70 is a mid-1980's guitar synthesizer that uses the older GK-1 divided pickup with a 24-pin connector. It is known for its ability to control a wide array of MIDI parameters and despite the fact that it is one of the slowest MIDI converters ever produced (with a 40 millisecond response time being typical), it is sought after for its control options.

The GM-70 does not have any built-in sounds of its own and must be connected to a MIDI synthesizer or sound module.

It has a built-in tuner, supports monophonic or polyphonic modes, and has connections for a FC-100 foot controller, EV-5 expression pedal, and DP-2 pedal switch.
