As you suggested, I download the Kalvtrask set, and I hear similar "thumping", though not as often or as loud. I say "thumping", that is a low pitch back-beat like a small
drum would make. It really resembles an electrical EMF like a motor or other load was being turned on. The pitch is low and does not really change where ever on the keyboard you play. And it is very random, and can't be reproduced methodically. But is very annoying to hear, because it just ruins the music. When I first tried GO about 3 years ago, this "thumping" was very prominent in all the bass notes. More recent versions have improved, but it is still in the manual keyboards. The CPU is not overloaded! And there is no clipping. I hear it in all sample sets. If it is a buffer problem, then I need help to increase the buffer, or some other solution. I hear the "thumping" in notes not being played all that fast. If there keying improvements in more recent versions of GO, I can't use them. The most recent version will NOT recognize my EMU soundcard
ASIO, nor will it recognize the USB connections, even though they are listed. Right clicking on the manuals with "listen events" simply doesn't respond. As I've said before, the ONLY VERSION of recent times that I can use is 1726. It always works, but many times will not recognize my second keyboard the first time I startup the machine and load the program. I've learned to restart and reload, and it always works after that. I've set up many sample sets with this computer and version 1726, and I can usually do it without too much difficulty. In case it wasn't noted, I'm using a 4-core AMD processor at 3.2gh, with Windows 64bit 7 pro version and EMU1212 soundcard. Thanks, Ken Barta
