Trouble using OMS with 9.1, any suggestions? Options

[slavproj]

I'm trying to use OMS 2.3.8 and am having trouble getting sound from the Quicktime extensions in OS 9.1.  I'm using OMS to play music scores from the Nightingale 3.0 notation program.  It all works on my old Mac (running 8.1) but though Nightingale works on my newer Mac I can't get my scores to play from the built-in speakers.  I don't use the program more than 2 or 3 times a year so I kinda hate to buy the latest version (US $89).  Any drivers or clues someone can suggest?

To turn QT Musical Instruments on in OMS you run a small application that came with OMS called OMS Setup. It churns around and selects which external and internal ports it thinks it can interact with. After it's made a selection you are able to highlight each item and troubleshoot. Initially mine showed QT Music with a crossed-out red circle through it. Clicking directly on the red circle brings up a dialogue box that gives you the option of turning the synthesizer ON. Once you've done that and closed that window the red circle will be gone from the QT Music on the available items listing. In my case I found I had to also Clear two other items that OMS thought it wanted to interact with, THEN my Nightingale software was able to use OMS to play scores using the built-in speakers on my Mac. Hope I've described this more clearly this time.
