I thought about putting this in the last thread I started, but decided that this was a little bit different. I've been using GPO4 for about a year now and Finale 2009 for about two years (after upgrading from 2004, which I used for about 5 years) on my family's computer (I just got out of High School) without a MIDI keyboard. All was fine in the world, until the GPO 4.02 update was announced, which I installed. As I was playing back a file that required about 4 instances of Aria, and instead of decent quality playback, I heard a chorus of popping. I immediately came to the forum and stated my problem, and got a few replies saying that the problem was dropouts and/or hyper-threading (which I couldn't turn off, because it wasn't even in the bios menu you get when you turn on a PC). Well, I couldn't fix the hyper-threading, and from what I've looked, there's no way to stop dropouts without getting a newer computer, which wasn't going to happen until about now. My final decision was to completely uninstall GPO and re-install without the 4.02 update, which was the end of the "dropout" issue. I figured I'd wait to install the update until I had a computer with better specs than the family computer.
So a few days ago, I got an HP Notebook (Intel Pentium T4500 (2.3 GHz), 320 GB Hard Drive, 4 GB RAM, Windows 7 (Home Premium), and I can't find any info on the sound-card), and installed Finale (2009c) and GPO with the 4.02 update, and... more dropouts with anything using more than about 8-10 MIDI channels. I'm assuming it has something to do with the 4.02 update, but it appears that nobody else has had any issue with the 4.02 update, so I'm extremely confused. I never have any other programs running while I use Finale and GPO. Also, from the 4 instance on (though I never use more than 5 due to crashing in the past), everything below a certain pitch (I want to say the C# right above A440) just doesn't play at all.
I don't want to sound like I'm angry at the Garritan people, because I'm not. I'm just really frustrated and confused as to why GPO 4 works amazing and then I add the 4.02 update and I hear a symphony of dropout popping (which could be cool, but I paid $150 for an orchestra, not a popcorn machine). Is there anyway to fix the update, should I just use GPO 4 without the 4.02 update, and/or is it even the update's fault? I'm just really confused and frustrated, and would be grateful for any help I can get. Please and Thank You.
