PT Freezes when recording midi

[muzishun]

When I record any midi data for a period of time, pro tools will lockup, the midi plasma meter will freeze, and playback/record functions stop working. The only resolution is a hard reboot. I've checked all my keyboards (which are running into a midiman midisport 4x4 USB interface) to see if a midi echo or thru is turned on, but they're all off. What else can I do.

Thanks

You can try some things to narrow down what's going wrong.
- try one keyboard at a time?
- try using the Digidesign MIDI interface (you have an 002 Rack, right?)
- if you're recording notes played on a keyboard, but actually generating the sounds in the computer (Reason, etc), don't run a MIDI cable to the inputs on your MIDI keyboard.

These aren't suggestions for a solution, these are suggestions of things to try to see if you can make the problem change. That's often the path to a solution.
