If you want to buy a breath controller you will have to move fast, as in October 2011
Yamaha discontinued manufacture of the BC3A.
This file now has all the sysex to assign transmit channel to 1 etc. for each
relevant keyboard. This sysex can be copied then pasted into the Midi-ox Sysex
window when you are creating Vl.syx, and if then sent to the keyboard will set
up VL controllers (most notably control change 13, the default for Embouchure -
which controls trumpet pitch and violin bow pressure - unless assigned to pitch-bend
as it usually is for saxophones).
I have not included some low-end keyboards like the DX21, DX27 and DX100 which
are not velocity-sensitive. Nor have I included some high-end keyboards like
the CS6X and S80 which can operate stand-alone with the PLG150VL plug-in board, and the
EX5 which contains the equivalent of a VL70m anyway.
