I collaborate with 3 other people on many projects, two of them use Artist and the other uses an iPad. That latter can only open projects and has to export new recordings as WAV to us, so we’ll ignore that one straight off! But the other two are 100% compatible with my full version provided I don’t use any feature they haven’t got, which isn’t really that much at all, mostly a few plugins. So it works well for us, and we’ve never had any problems at all. I believe they started with Elements but upgraded to get the Lanes feature for multiple takes and comping.
