What OS are you running on your Powerbook? The current demo version of Drumagog only works under 10.4 or later, since it's based on the latest Drumagog build, 4.11. Older builds work fully with 10.3 and 10.2, but the demo is limited to more recent operating systems.
Thanks for the reply....im running 10.4.1...The top half of the plug appears when i try to open it but no controls.Almost the same as when you close a plugin.
