All Roland and Roland-compatible cables fall into two basic categories: either the early version 1 cables, with a latching-type mechanism, or the later version 2 cables with a pin-type mechanism.
Since all these cables share the exact same pin configuration, they are electronically completely interchangeable. There is no difference between the wiring of a GR-500 cable and a GR-700 cable. Electronically, they are all identical. However, the later pin-type cables are slightly more universal, and provide a more secure physical connection when used with pin-type connectors. The pin-type cables also work well with latching-type connectors.
Please watch the video, and see the chart at the bottom of the page for a list of devices and their connectors. Also, Mogami wire is used universally in all the cables.
Please note the Korg Z3, because of its recessed design, must use the later, pin-type cables. Look to the repairs page for more information on maintaining and repairing cables. The proprietary Roland connectors were made by the Japanese connector company, Tajimi.
