...be prepared to pay an extra $40 for the discs. I have 30 Mbps download speed which I check often. It smokes. The download service from Cakewalk is about 90 Kbps.
Sonar Producer comes in 4 parts. Part one was downloading at 91 kbps, and was showing a 5 hour download time. Sonar only gives you 300 minutes before the download links expire. According to the guy at Cakewalk customer service, if your time limit expires during a download, you will have to start that download over again. I calculated that it would be nearly impossible to download it, based on their current speeds.
