The A/B/C/D Rotary switch accesses 3 additional memory expansion banks for loading more Synth patches.

QuoteRoland GR-700 MIDI Input DocumentationThanks so much to Ben Miler who sent me the "holy grail" of the Roland GR-700 MIDI input modification: the paper documentation on the exact features of the MIDI input modification!Download the original MIDI Input Documentation (pdf)While I reversed engineered many of the features, the part I like best is an explanation of the improved tracking in version 1.5 software: sensing the pitch of the note in one half cycle (waveform).While this is the modern standard, the early versions of the GR-700 required a full-cycle. And the V1.5 software lets you select which mode to use: with the switch in mode 2 (the middle position), your GR-700 uses the original tracking algorithm, and in the mode 3 position, you get the faster tracking!
