I have GPO4 on Finale 2009 (and am quite satisfied with both), but I'm having a few issues:
When I'm playing back music in finale the Garritan instruments will randomly make a popping sound after a few seconds (like a snare or a bass drum sound, even if the instrument is a harp) and then just stop as though the sample can only sustain for a few short seconds. I've tried reloading the instruments, starting the score completely over, and using the "normal" versions of the instruments, and nothing seems to be working. It doesn't do this in stand-alone version either, and the problem got worse when I downloaded the aria updates. It would be much appreciated if I could get some help with this issue as the annoyance causes my eyes to do this.
Oh, and if it helps, I don't have a MIDI keyboard attached to my computer.
