Thanks for doing great work on this software!
Like I said, it replaced a hardware device that cost about $1,000, so I would have gladly paid ten times as much as the current price for Cubasis 
On a more serious, related note: I think there’s a market for a Live/Pro version of Cubasis. I’ve scoured the market for something that meets my needs of having something that’s rock-solid/reliable and that can do things like play back multiple audio streams, MIDI tracks, etc. and there are very, very few options for that if you don’t want to have a laptop on stage (I don’t want to look like I’m doing my taxes when I’m playing a show).
There are all sorts of neat features you could add to Cubasis for that Live/Pro use, e.g. a simplified playback screen that I’ve posted a feature request for here, and I’m sure you could think of many others:
