Midi Messages for GCX two and Three

Post by dbetters »

Could someone please tell me what channel and message numbers I need to use in order to have instant access to GCX 2 and GCX 3? I see in the manual how I need to program my footboard for one GCX...but what about when there are three GCX? Any help is greatly appreciated!

If you are not using a Digital Music Corp. / Voodoo Lab controller (like Ground Control or Ground Control Pro) then you will need to have custom chips installed into the each GCX after GCX #1. These are user installable and do not require any soldering. The custom chips will will force each GCX to respond to the following control Change messages on MIDI channel 16...

GCX #2, 88-95 (Latching), 112-119 (Momentary)
GCX #3, 64-71 (Latching), 96-103 (Momentary)
GCX #4, 56-63 (Latching), 72-79 (Momentary)

Give us a call or write to info@voodoolab.com for current pricing and availability on the custom chips for the GCX.
