As far as I know, most devices don't use the LSB >because the MSB allows selection of up to 128 banks. and my face is red because I knew about "smooth" controls that let you send 14-bit values by sending to two 7-bit controllers that are 32 positions apart. and of course 32-0 = 32... so controller 32 must be the least significant bytes of controller 0! <http://www.ibiblio.org/emusic-l/info-docs-FAQs/MIDI-doc/> has all the MIDI specs in just text format -- the best way. very handy. >The VL70 has an unusual implementation of bank select, since it has >only twelve banks. Twelve? Surely, uh, eight? Four banks (2 programmed, 1 custom, 1 internal) times two modes (Wind/XG -- the XG is interesting but not for a wind player...) >It appears that Yamaha is allowing for multiple categories of banks, >in order to accommodate various General MIDI formats such as XG.

Wow, that's so arcane! >Has anyone encountered similar implementations? No -- but the Peavey PC1600 series has provisions for all sorts of wacky ways to split up parameters so they must have encountered a lot of special cases. /t <http://ax.to/fortune>.........a new fortune every minute. <http://FortNY.com>..................Forteans of New York.
