Multiple Program Change Transmissions

Hi, I try to operate with mine but not sur of your explanation. I don’t find how to send a custom PC#, with the “Transform Pipe” we can transform a PC# into a PC# but impossible to choose wich PC#… I should miss something.
My final goal is to use a TC Electronic G-System with multiple devices and this product can only send a custom MIDI PC# map and associating MSB.
Finally I’d like to send a PC# from the G System to the midihub and change it so I could send 4 different PC# on 4 differents MIDI channels. It seems more harder than I thought :frowning:
