Dennis, When you import the wave files, provided they're stereo recordings, there's a check box in the Import dialog that you'll need to check to tell Sonar to bring them in as mono tracks. Hope this helps. Mike ----- Original Message ----- From: Dennis Madsen To: ddots-l@xxxxxxxxxxxxx Sent: Sunday, October 10, 2010 16:15 Subject: [ddots-l] Seperating tracks Hi all! I have started working together with another composer. He have send me some wave files to work on. Is it possible to get sonar to split does wavefiles back to tracks again after importing them? If yes, How do i do that? Take care! Dennis
