Problem controlling multiple midi devices

Post by jeff_g » Tue Oct 03, 2017 2:15 pm

Hi! I’m trying to control 7 midi units with my Digital Music GCPro, Each on their own channel. The first 5 work great, but the last two won’t respond to program changes. I’ve changed the order, and regardless, the last 2 in the chain don’t switch. Any advice? Thanks!

Well that is quite odd. When you swapped the order of the devices, did you also change out the last two MIDI cables?

Do the last two devices show any MIDI activity, if even just a flashing light to show data is reaching them?
