I just got my black grand for giga 3. I can't get any of it's patches to load. I get the same message I get when I put too many samples in memory. I am running a p 4, 3.06 speed, 1 gig of ram. Is it possible that one gig of ram can't handle this piano? I'd appreciated any advice.
In Gigastudio go to File > System Settings > Synthesizer > Stacked instruments. Now lower the value. Someone else on the forum suggested setting it to 128, try it. This solved my GSDLL problem. Later you can raise the Stacked Instruments value if you need more memory dedicated to that feature. Play on!
That's certainly an error message you get when you're low on memory, but I guess you can get it for other problems as well as it's a pretty general message... I don't have Black Grand yet so unfortunately I can't try it for you, but I'm sure Worra will try it if you contact him.
