Hi, i had a look at XG-MIDI-Tools to send 14bit CC to ableton from max (via software virtual midi cable, midi yoke)and even thoughableton receives some midi it repsonds really strangely. Is it actually possible to send 14bit absolute CC messages on all controlers or only some controler number allow for 14bit numbers.
i hate hex and binary…
CC 32-63 are mached to CC 0-31, so you can only really send 14 bit
messages for these. In addition comes the NRPN and RPN messages, but
they are really using 4 CC messages to transmit one message.
I haven’t used XG-MIDI-Tools in a long while myself, but if you find any
flaws, please drop me a mail.
