Has anyone used Band in a Box on OS 10.3.x. I've been told it runs in Classic Mode with QT 6.03 but I'm a little worried about compatibility problems. When I downloaded their demo (version 8) audio playback was jerky (dropping beats). PG Music says version 11 works in OS 10.3.x. Anybody out there that can speak to this issue? Anyone actually using it on OS X? If there are problems, are there any workarounds? Alternative software options?
