No. My first DAW was Twelve Tone Systems’ Master Track Pro (a billion years ago). It was MIDI only no audio, it’s now Sonar. Went from it to Logic until they dropped the PC version. Been using Cubase since - now with Cubase 7.
My interest in Cubasis is strickly as a sketch pad that I can use from the comfort of the hamock at the cottage or travelling, etc. and be able to get ideas back into my desktop to expand upon
Cheers
