This is a good idea, but the program is still a beta and UNSTABLE. I have emailed Unsanity several times, and have never received any reply. It crashes OS 9, 10.1, 10.2. Not minor crashes, where you can uninstall Xounds and all is well, but MAJOR ERRORS, where you must erase the disk and reinstall the system. Archiving and installing also will not solve the problem. I have installed Xounds on three different computers, and it ruined the OS on all three (two iMacs and a PowerBook), to the chagrin of my family. You may risk a very careful install, and run DiskDoctor every week to fix the damage, but eventually, Xounds shall crash your system. I have spent many long hours on the phone with Apple Care for educators, and the solution has always been the same: wipe the disk and trash Xounds. When will I learn? This review refers to all versions up to 1.3. Buyer beware!
