Hi Caelia!

I was using a regular Windows machine using USBPcap and Wireshark to do a similar job. I put down some notes on how to capture the raw data in this document:

Ah, yes, Wireshark. I've used it a bit in the past for some very basic network troubleshooting, but I've never learned to use it very well. Maybe I will now.

Apart from that the sysex specification (also reverse engineered ) for the Arturia Beatstep might be of interest to you:

Great, I'll check that out!

In the comments on that last page someone mentions the MIDI console inside Arturia's app. This seems to log all messages (including sysex) sent and received from a connected device. This should make things much easier.

Cheers,
Daniel
