My cpu is fast enough and I have enough RAM (even if its just 4GB) but still and I have an ok soundcard. I think it might be the RAM but not sure, anyone that has experience the same problem? Sometime it crashes 3 times in 5 min and sometimes not at all. have turned of all things I don'r need when I am using the Music Maker.
I use to have that problem on MMM 17 premuim. It might be different on MMM 15, but go to settings and hit (reset to default) I usually reset it everytime i start a project and works fine. Plus you should try optimizing the RAM.
