I just had 4 great hours with Cubasis, it’s really fun to play with!
3 things that occured to me:
When I unsolo a track all other tracks are unmuted. Is that on purpose?
The samples get cut off suddenly on some midi tracks when using the built in sound. It works with other apps, though? Processor bar shows about 50 percent (iPad 3), maybe 10 audio tracks and 6 effects alltogether.
Restarting doesn’t help.
The grid resolution is still not fine enough when disabling it. It can be hard to line up audio properly.
Doubling percussive sounds and parallel compression is impossible this way.
