Create a duplicate in/out ports of the Matrix Ctrlr. Really useful if you own several Oberheim to avoid a bunch of midi cables between your synths and the Ctrlr.
Furnished with a DB25 flat ribbon cable to connect to the P12 EXTENSION port of the Matrix Ctrlr mainboard and a snap in DB25 female connector. The additional parts like Midi DIN5 connectors and DC 2.1mm power plug are included.
The printer DB25 cable to rely the extension and the Ctrlr is not furnished as it is rather easy to order it in your country (heavy weight).
