The generation time on the plugin is the same as for the program (rendering) or RealBand, and is usually 10-30 seconds depending on how many tracks and how many bars. 10-15 minutes would be off the charts, and something that we’ve never seen, and we would need to find out more information such as what your system is doing. Offhand, the only thing I could see slowing down things to that extent would be an antivirus program or a very slow hard drive. But there is always the “actual cause” which can be something that no one figures out until it is figured out.

Anyway, for most people it is 10-30 seconds and please let us know some info on your system. Task manager info during this would help, to see if there is any CPU activity from bbw4.exe which is the helper program.

Have Fun!
