Saturday Synth Porn: Synth porn or not?
The Roland GR-500 Guitar Synthesizer was Roland’s first guitar synth, pre-MIDI.
The synth module is controlled by a guitar with a special pickup system that connects to a synth module via Roland’s own 24-pin interface. It uses CV/GATE signals generated by the guitar’s pickup system.
The synthesizer module included Bass, Solo Synth, and String sounds. Sliders are available to adjust the VCO, VCF, VCA, and LFO sections, but no patch memory.
