This is exactly what this projects needs more. Good examples that limit themselves to one specific area in simple way.

I’ve wanted to use this project to create a control panel for my Yamaha P50m piano module that has a ton of undocumented sysex commands. I’ve reverse engineered a lot of it, but since Yamaha requires you to add checksum to any sysex command, it’s not so easy to interact with it using just simple saved commands.

thanks, and I hope you get onwards with your example so the threshold of using CTRLR gets lower ?

sending the checksum is not so difficult, it is a Ctrlr routine,
using ‘z(n)’, where n is the number of bytes you want to checksum.
