I dont know if anyone else has this problem or its just me
When activating the key tunes it doesnt work but when i change the rx midi right to chanel
One it works but then i get interference of the left and right voices of the keyboard,when i owned the audya 5 this was not happening?

I also have an AUDYA 4 and an AUDYA 5, when I play the
AUDYA 4 from the AUDYA 5 I don't have any problem 'cause
I work with two MIDI channels separately, "MIDI channel 2"
for the LEFT and "MIDI channel 1" for the RIGHT, (in
the AUDYA 4 set Channel Rx Right 1, Left 2)
and I can play the KEYTUNES in the AUDYA 4


But I also have a M-AUDIO master keyboard to play
the AUDYA 4, this master keyboard M-AUDIO sends only one
MIDI channel, in this case I have it set on the MIDI channel 1,
then if I play the AUDYA 4 from the M-AUDIO keyboard
I have to change the MIDI Channel Rx configuration of
AUDYA 4 to "Global 1", and it works to play Left and Right,
but the KEYTUNES don't work.
