I'm changing my orchestral templates completely & importing Midi1 files along with a few exported audio tracks.
It's works well. I'll open a project both in C7 & X2 each loaded with instruments/ samples along with VEP5. I can switch between them all including playing audio to double check parts or presets.
I've got 40 projects left to do this way & will eventually complete them all in C7. This is the best way for me to learn the ins/outs of a new program.
By the time X3 is released (I'm guessing in a few months) I'll know which one I'll continue using as my main DAW.
