oke... thanx uprising, i will try that, and i am using chrome, so i will switch that although i had no problems in the past, but i use a lot of effects and synths these days, i will try out your advice, thanks my friend!
Here is a suggestion that may help you Build on to your tracks more
check it out go to your task manager and Shut down any unnecessary processes then If you are using Mozilla Fire fox Go look where it says Plug in folder and Right click it
.. then click on priority and switch it to hi.. there is another way to get a lot of power from your pc as well By simply turning off any Re verbs that you have on the table. They eat a lot of CPU and i mean a LOT so shutting them off until you publish will help a ton..
also Try bouncing your drums or some of your simple sounds into audio tracks.. Audio tracks do not take much space and is a good way to make room for more layers of a track. I do all this on a regular basis and is the only way i can create some of the tracks that i create due to the complex nature of my style.. I hope this helps you
