I recently purchased the music maker 17 premium on-line, directly from Magix. I am confused about why this program is stuttering and occasionally skipping during play back of instruments that I recorded. I downloaded an up date from Magix which was suppose to correct some issues,. .but it didn't. I am desperately just trying to get a got mixdown of my original music. Did I make a mistake when I bought this software? Should I have bought Samplitude Producer instead? Is there a anywhere on-line to download the full version of Samplitude for free? I already have over $100 wrapped up into a program which is totally useless to me at this point. Or is there a patch to correct this stuttering problem I am having? I have a brand new computer, windows 7, plenty of ram and hard drive space.
