Dunno ?

Have you considered using an Arduino USB Host shield and doing away with the RPI?

I was wondering if there's something else I'm not doing prior to sending this message. Do BTS and Floorboard put the Katana in some sort of receptive mood? Electronic chocolates, or dinner with wine?

I have no trouble speaking sysex to my Katana from an RPi.  There must be something very fundamental going wrong.  If you like, have a look at my languishing project:

https://github.com/snhirsch/katana-midi-bridge

That code communicates just fine with the Katana in both directions.  I've run it on RPi, Beaglebone and a Linux desktop machine.

Is there one which supports non compliant (in other words Roland/Boss) products? It could be the RPI I suppose, but I'm unscientifically hopeful that it isn't. I'm getting good performance with PC and CC from it.  In another thread I mention that my expression pedal (midi thru teensy/RPI combo) behaves as though it was part of the amp, no matter how fast it is operated.

There is a GitHub MS-3 project by Forum member MrHaroldA,
who uses an Arduino USB shield 2
to use his Arduino to talk directly to an Boss MS-3, so I should imagine a Katana would work the same

Glad you have things working.  We software folks often find the problem lies between the chair and the keyboard :-).  Just part of the game!

FWIW - the Boss SY-300 MIDI Implementation doc goes into some detail on the generic Roland / Boss SYSEX message format
