MIDI on the SAM Coupé

Hi, I've been looking at 8-bit micro's recently and stumbled accross the SAM Coupé, which has some astounding capabilities.

I was particularly interested in the MIDI out. Luckly SIM Coupé lets you set midi out to the host computers MIDI player so it was just a matter of outing some bytes to port 253 to get it working and since GM is well documented (e.g. https://cmtext.indiana.edu/MIDI/chapter3_channel_voice_messages.php) I soon got a quick MIDI player working (below for example is a BASIC programme which loops through all MIDI instruments and percussion).

My question is mainly wandering how much MIDI out has ever been used in games/demos? For example if people would have gotten a Roland SC-55 or similar and used the SAM Coupé as a MIDI machine. I see there was at least one MIDI sequencer but not much more than that.
