Skrydstrup SC1 & GCX

Post by olliaimola » Sun Jun 02, 2019 10:42 am


I’m thinking of getting myself second GCX. I’ve read a post from here that says that if I want to use different controller than GCP with several GCXs there are two options: send sysex message or insert custom chip to second and third and fourth GCX.

Skrydstrup SC1 controller can’t send sysex messages so how can I get that chip that would make the second GCX to respond to different CC than the first? And is it easy to install?

Best regards,
Olli Aimola

To get the replacement chip you would want to give us a call or write to The chip is in a socket so there is no soldering involved.

A GCX #2 chip will force the unit to respond to Control Change messages 88-95 on MIDI Channel 16.

I hope that helps!
