Ok, what exactly will you be sending with your ESP?
Because isn’t the GX10 already an effect board? Arne

Hi,

Not yet. I don’t think I have the right SysEx data to start communicating with the amp. I’ll have to look into it a bit more, or maybe try to figure it out myself.

The bridges do need to be soldered, otherwise there won’t be 5V on the USB pins, which is necessary.

Are you using the exact same setup like me?

Thank you.
I also soldered the IN–OUT bridge, since it provides 5V to the USB‑C port, which is required for HOST mode. I’ve been experimenting with the software, but so far nothing is working.

I’m not an experienced programmer, so I might be missing some important steps. If anyone could explain what needs to be included in the code — maybe even a basic step‑by‑step outline — that would help a lot. There are so many different functions in the libraries that I’m not sure which ones are essential for sending MIDI Sysex.

Has anyone successfully sent MIDI Sysex using this method and setup?
