Thanks, Mac (again) and Ron, for the confirmation that Biab can't do it.

I use a couple of other softwares from time to time between the midi-in and midi-out, and one of them has probably more midi parameters than Biab, so I'll look at that. The trouble is (as I said at the beginning ) I'm pretty much at the borders of my understanding here - I'm not even clear exactly what midi value would be involved.

(for what it's worth: my midi-out is a Yamaha PSR K1, which was basically a short-lived variant on the PSR 293 and 295 models. Cheap kit as an instrument but (to my ear) a pretty good set of samples as a 'hard-synth'. )
