Hey, I have a very similar setup! HX Stomp, Morningstar, C4, and the new micro.ghost.
I had the same initial issue because I wanted to put the midi channel to the C4 on channel 3, but it wasn’t working.
I contacted Disaster Area, and they informed me that there was a glitch and that a firmware update was coming soon. (The glitch was that channels 2 and 3 on the micro.ghost are reversed from the manual description)
They already have the firmware out and I did the update. It all runs smoothly now!
From my email with them...
“Firmware update tools are here:
disasterareadesigns.com/files
And here’s a video showing the update procedure with the MIDI Baby. The steps are the same with the ghost, except you must flip SW8 (far right) before inserting the USB cable to start the bootloader.
Once you’ve updated you should find that the DIP switches agree with the text on the lid and in the manual.”
I hope that helps!
