Big troubles with midi tracks

[Riccardo Corbari]

Here's an expanded version of Chris's recommendation, which has helped many customer with strange MIDI issues:

Go to MacHD>Users>your account>Library>Preferences>By Host and trash 'com.apple.midi.a bunch of numbers and letters.plist'.

Go to MacHD>Users>your account>Library>Preferences and trash 'com.apple.audio.audiomidisetup.plist'.

Empty the trash and restart, then see if everything is working.

If that doesn't help, we need to know which MIDI interface you're using and if it has the most current driver installed.

still problems. I can't understand why

As suggested above, did you try new midi cables? Also did you try installing the Midi I/O driver again? (off the PT installer for the same version of PT as installed)

It's impossible to offer you suggestions, when you don't list exactly what you've tried.

This may sound really dumb, but check these places.

MIDI Thru in PT?
MIDI Input Filter in PT?
Local control on synths?

MIDI troubleshooting in my opinion is far worse than audio signal flow troubleshooting. Give me a busted channel strip on the console any day of the week over a buggy MIDI system.
