No MIDI sound in ProTools

[kbeartx]

G3 400, 256 MB RAM, OS 8.6, ProTools 3.4, OMS 2.3.8, no external MIDI devices (just QT)

I can play MIDI files just fine (with a shareware app called AMP), and I can play audio files with ProTools (at least the demo session it comes with), and I can import MIDI files into ProTools, and even 'play' them (the session 'slider/cursor' moves across the MIDI notes, the level meters move on the tracks, but no sound comes out!

I just updated my OMS because I thought that's where the problem was, but no dice. I checked in OMS setup, and it's appropriately configured to use QT as the MIDI 'device'.

Any ideas, theories, help?

TIA,

Kbear

I think the problem is that QT MIDI Instruments require the use of the Mac's audio system. This system is not available for any other software while Protools is running.

Check this setting:
In OMS setup/preferences: 'Use serial DMA driver when available' must be disabled (so NOT checked)

Thanks for the suggestions, guys!

Arno -

I tried that setting in OMS, but it didn't change the problem...

BorgBilly -

do you know if I got a sound card, such as the AM III, if that would 'free up' the Mac's audio capabilities and allow me to mix MIDI and audio using ProTools?

thanks again,

At the suggestion of Lee Marconi, I tried to see if I could get audio out of my MIDI player at the same time that ProTools was open.

I actually did better than that: I was able to playback a PT session at the same time as I played a many-instrument MIDI file, all audio tracks playing simultaneously (it sounded awful, but it did prove the point).

But I am STILL unable to hear ANY audio from MIDI files played using ProTools!

Any other theories, suggestions, test?

Try going to Options (I think) and clicking on Midi Patch Thru - that should do it.
