I have ProTools Le6.2, uptil now I have exclusively recorded guitar and drums but have just recently got into to midi world. I am having currently having trouble with system. Has anyone upgraded to 6.7? does it really handle midi stuff better?

Pro Tools 6.7 does have a number of new MIDI features since 6.4, such as Beat Detective, the ability to time-stretch MIDI data, a Step Input mode, a very cool Tempo control section, and others. My favorite new thing is regarding patch names. I use a Roland Fantom-S88, and to have access to patch names, I had to modify an existing patch names document extensively to match my patches. Once this was configured in 6.4, the banks showed up with an obscure serial number, not the bank name, which was a pain - in 6.7, it appears Digidesign fixed this, as the Bank list shows the real Bank names now. In my opinion, 6.7's MIDI improvements are basically catching up to other sequencer's features. I can't say it handles MIDI better, but 6.7 does offer more options (I've been using Pro Tools' MIDI features since v5.0). What specific problems are you having?

well I just updated to OS 10.3.7 and can no longer open ProTools. After doing some reading, I guess I have to "downgrade" back to 10.3.5?
The problem I was having before the crash was that I couldn't record more than 1 track of midi. I use Reaktor and I have G4 1gHz. Thanks for your input.

I'm assuming you were Shift-clicking on the record enable buttons for any additional MIDI tracks to be recorded to (except the first one selected)? I'm also assuming you are using different MIDI input devices for each MIDI track in question? I'm upgrading my PowerBook system software when it becomes available, and I haven't had any problems with 10.3.7 (although I have the luxury of having a G4 desktop, and that one I keep at Digidesign's spec for system software).
