I'm running into an issue with GPO and Finale 2008. Crackles! Lovely little things that can really ruin your day. I'm working on a project that is using mostly strings plus flute, oboe and french horn (not all at one time). For a more realistic string sound I'm doing the following: For Violin 1 I have Gagliano 1-3 and Stradivari 1-2 together on one channel, Violin 2 has Stradivari 3 and Guarneri 1-3 on another channel and so forth. I had used the Violin 1 & 2 Lush as well for a fuller sound, but the crackles got way too bad. However, the crackles come back anyway whenever the solo horn plays. I am using the Kontakt 2 player. Under the DFD setting under options I have the amount of memory set at around 60 MB (had another problem earlier and was told not to set this too high). I have tried lowering this and raising it, but it made no difference. I've got 4 gig of ram on my computer so I should have more than enough ram. My sound card (M-Audio 2496) has the buffer rate set at 256 and a sample rate at 44000. Latency is at 6 ms. Is there some other setting I should be looking at? No other program is running other than anti-virus software. Going back to stone knives and bearskins for writing music would really be a drag!
