I've been playing with si drummer in Sonar Le. I'm dragging the drum parts to a track - the track plays them, but they're messed up. They sound jumbled up or slow or something. Any suggestions?

TTT

I am having the same issue, and the hardest time getting an answer. I drag the beats I want into my project and when I play them back they are missing hits at various points through out the beat. I have submitted my issue to customer support and am hoping to hear back from them soon. If you figure it out, please let me know...this is very frustrating!!!!

Do a search on skipping MIDI, or unstable playback. It probably has to do with the buffers for Recording and playback, which is found under Audio/Options. They will need to be raised or lowered, can't remember right now, but that should get you started. Sounds like definitely in latency in playback. Good luck! If you go to User Control panel at the top of this page, you will see signature and comments, its for your PCs specs, without knowing what you are using, its harder to help, although there have been problems with the forum working right. But you will get more answers with that info provided.

What sound card are you guys using on the computer? 

Most often the soundcard in the box from the factory and sound blaster updated gamer cards are the problem. Synths (midi drums) take a lot of processing power and the factory cards don't cut it. 

You might be able to get it working somewhat by using MME drivers, 44.1khz/16 bit settings and increase the latency slider and buffers a bit. 

Fantastic!!!! Thanks for the help, guys!
