I've worked on this just a few days ago. Ctlin only serves for 7bit
CC e.g. for midi messages made of 3 bytes.
If you work with BCR-2000 or BCF-2000, and you want to feed into max
Pitch-bend 14-bit it doesn't work because these machines send only
7bit pitch-bend values.
If you want to work with 14bit controllers you have 2 solutions:
1- programming your BCR knobs as CC 14-bit and in Max using midiin
and translate raw midi messages (6bytes of message)
2- programming your BCR knobs as NRPN and in Max the same as 1 but
messages are 12 bytes long
There is also an object in the jasch collection to feed into Max
NRPN. You'll have as output values between 0. and 1.
Here's my abstractions.
hope this helps
