Debugging an existing DAW to see how they do it under the hood is an interesting idea. Haven't done that yet.

About another interface: I do want to keep the application supporting cheaper interfaces such as the Scarlett, because the target audience (hobby musicians) will be using those. Still would be a nice upgrade for me!

Tracktion looks like an interesting project, thanks for pointing me to this!
