Thanks I thought there was someone here that used it. I got it originally to do backing tracks but found that using my tablet with a mp3 easier. I used it with Sonar to convert midi files and worked well.....I never got the usb stick to work reliably. I am going to try to get it to load on my Windows 10 machine then see if I can get it to work with BIAB. What is the .PAT file for?
