Setting channel-number: keyboard interoperability ?

[Peter Billam]

Greetings :-)

On the keyboards I have (all M-Audio, so not a random sample...)
the channel numbers are entered using the white keys:
on the 88-note keyboard using keys treble D (62) through e~ (88),
on the 49-note keyboard using bass D (38) through treble E (62)

I'd be delighted if that was some kind of de-facto standard, so
that we would have interoperability between different keyboards.
Is that the case ?

( context: I'm writing an app which uses the midi-keyboard notes
to control the app; not yet really announced, but see:

)

Whoops... That should be:
