Ahh ... sorry!
I missed that ctrl 0 (MSB) is mirrored as ctrl 32 (LSB), perhaps because
I get by with 8 sounds (or something ...) when I doodle at home.
Who needs such a vast sample library? I can see the usefulness of having
various dogs, cats, craws, crickets, seagulls or traffic-jams to set the
the tone of a scene filmed off-site. but 127^3 is kind of a huge number.
Is it even implemented on the receiving side?
Inquiring minds wants to know :-)

Hi everybody!
I wonder what's the common behavior for a synth/sampler regarding MIDI bank
select messages. You might know that MIDI has splitted bank indeces into two
values MSB (coarse) and LSB (fine) value. So the "optimal" behavior would be
a device / sequencer to send a MSB and a LSB bank select message to change
the current bank. But many older keyboards for example won't do that. I've
heard most of them only send MSB bank selects, while few others send only LSB
bank selects. Is that true?
hello,
i haven't seen such a keyboard sice around 1995. I dont think that
any recent midi keyboard uses MSB only (or LSB only) bank
controllers.
If yes, how should you handle that on
synth/sampler side? Because you know,
using just MSB messages would only allow to switch between the following set
of banks:
{ 0, 128, 256, ... , 16256 }
while using just LSB messages would only allow to switch between the following
set of banks:
{ 0, 1, 2, ... , 127 }
So should a synth stick with that behavior or should it detect if a device
either only sends MSB bank selects or only sends LSB bank selects and then
actually remap MSB-only selects to a set of:
{ 0, 1, 2, ... , 127 }
Keyboards that only support "MSB only" mode (or "LSB only" mode)
are just too limited and there is no workaround that will "just
work" with both modes. AFAIK, there is no standard way to detect if
a device will use MSB, LSB or both. According to midi standard the
bank number is (LSB + 128 * MSB), so the "Both" mode is the correct
one to use. That's also what most users would expect.
