However, am I right in thinking that with soundfont mode this, paired with a Pi3A+ and a DB15Midi on my card's gameport, gets me both MT32 and GM functionality? Yes Actually, I guess I need a PCMIDI rather than my current card's gameport, right? That's even better, as it would give you intelligent …

I already found these videos, but it seems that this guy is unwilling to share their knowledge (feel free to correct me if I'm wrong). That is unfortunate, did you really contact him ? He seems friendly, if i look at this youtube comment (at video https://youtu.be/-R5K8wFJCRA) youtubecomment.png …

Can I use the chill iii + mccake without the floppy power connector on chill, only with the barrel 9v adapter? Yes : the connector on CHiLL III is a power OUTPUT, feeding power to the power INPUT at McCake. So the normal way to use an 'unmodified McCake' would be to add this cable : CHiLL III --> …
