Thanks for your reply.
I verified using another software application that my keyboard is transmitting
MIDI on the channel I specify in my keyboard's user interface.
However, when I open a Logic Pro 9 multitimbral software instrument, and my
keyboard is set to transmit MIDI on channel 1, the plugin show MIDI received on
a random channel that appears to be tied to the project. For example, in one Logic Pro
project, MIDI is received on channel 11, and in another project MIDI is received
on channel 4.
