No Midi output

[billybroadsword]

I am having an issue with my MIDI in PT. I am running Windows 7 and have Pro Tools 8.0.1 with an original mbox. I realise that there is a further upgrade to 8.0.3 but my mbox won't be compatible

The problem is quite simple: I cannot get PT to send midi to any external ports. I have quintuple checked that I am sending to the right place in the channel I/O and I have made sure that all of my external racks are receiving on channel 1.

It makes no difference whether I set up an instrument in PT midi studio or just directly out of the MIDI interface.

I have tried three different bits of hardware - mbox2 (borrowed for troubleshooting), midiman 2x2 (nightmare just to find the correct driver) and a MOTU express XT. All have the same problem - input to PT is fine but no output possible anywhere.

PT will also not receive any midi unless 'midi through' is checked in PT. I don't remember it being like this before.

I would really appreciate help as I am at my wits end.

Thanks.

I have the same problem. PT 8.0.3, Windows 7 beta drivers, mbox 2 mini

After numerous re-install and the same result, I searched the Windows HD forum and found the solution:

Been having trouble getting MIDI out of PT 8 on a Vista platform myself and finally found a solution!!
