Higher buffer sizes will introduce more latency into the system but setting the buffer size too low may cause glitches in the audio. 512 or 1024 are usually safe choices.
Glad that from now on you don't think that you wasted your money.
Those "problems" and "angrys" could be prevent, if there would exist a good FAQ Area and well done Usermanual. Those things saves time and makes the use of the software mor comfortable. Resolume is not a shareware or freeware, cost a bunch of money and in my opinion, the user has a right on a well written usermnanual.
I have another special Software for Eventmanagement. The manual and the FAQ area on the membersite is well built up, including a trouble shooting part. The manual and FAQ Service is updated several times a year and saves at least the owners of the software and the support a lot of time.
Anyway, thanks for helping, again.
Kind regards.
Robert
