I have looked at dozens of these since being advised of their existance. Adour looks really exciting. However, I am as tied to Cakewalk as you to Cubase. All those nice pluging, audio-engine optimizations, etc. My main reason for staying with windows here is the MIDI software that are my main tools, before I get to Cakewalk. Jammer Pro, Ntonyx software, et. al. No equivalents or ports in Linux yet. Someday!
