Hi, I currently have a intel 3.0Ghz core 2 duo computer with 8 gig of ram running on windows 7. I am only using about 2000 channels this year. I have set all the channels up, and put the music track in (mp3, 128kbps 44100) but when I press play the music jitters and and echoes. I looked at the cpu usage during playback and it goes between 85% to 98%. I turned off all the music wave forms and other items and it drops the cpu usage by about 5-10 % and the jittering is a little better but not gone. I am assuming that it is the computer not having a powerful enough cpu? Do i need a new computer?
