i am having trouble recording my midi keyboard psr 295 usb interface. the problem is
e.g
if i record on a midi track from the keyboard e.g only bass part.
and then try to record a string section on another midi track.
so as i change the voice in the 2nd midi track as string the voice i get from the 1st midi track which was bass, now also becomes strings voice.

i.e both tracks play with the same voice selected on the keyboard.
