Ah, yes, that can do some of the work!

So basically, MIDI lets you get one system (such as a DAW running on a computer) to talk to several others (such as the A-112 module), and there are many well-defined musically relevant commands of what the former can tell the latter to do, such as start and stop playing notes... Sysex -- system exclusive messages -- are MIDI's way of saying "I don't know what this information is, but I'll blindly relay it to you." So bearing in mind that some DAWs and, by the looks of things, this C6, are happy to do this blind relaying of data, that means no one needs to write a program from scratch to do that. So that's good.

We still need to translate .wav files into the A-112's native format that runs over the top of sysex, but I'm pretty confident I can reverse engineer the DOS program. I'll give it a waveform, see what it's sending, and see how they compare. Hopefully it's not doing anything *too* cryptic. :)

All the best,
Zoë.
