[Finale] Increasing Playback Memory

[Gerry Kirk]

I am trying to play, and create a playback file, of a full band piece I wrote. 
The composition is only 4 1/2 minutes long, but with 42 staves, playback of the 
full-sounding ending fades in and out. FINALE intermittently omits sustained 
notes and instead plays the shorter countermelody parts. I'm using SmartSynth 
instruments, not Garritan.

Is there a way to increase computer memory, or FINALE playback capability?
Or is the best solution perhaps to create a playback file with condensed sounds 
and/or fewer staves?

I'm using FINALE 2010b, on a Mac with 4GB memory, 3.06 GHz Intel Core 2 duo, 
running system 10.6.2

As always, thanks for any suggestions.

Gerry Kirk
