Since rehearsing is currently impossible I, Cubase user since Atari times, convinced my mates to invest in audio interfaces and Cubase AI 10.5 so we can rehearse and / or develop ideas online, one by one.
I had to realize that setting up Cubase once and for everybody is impossible. The project file seems to store the last configuration only. The subsequent user has to reconfigure everything, and repeatedly.
Things would be easier if Cubase could memorize various computer / interface setups including track settings and recall them automatically.
