Hey Clark
nobody is trying to force you ;-), but even though I love Cantabile to death, all my production work is done in Cubase and Reaper. It’s just the question of the right tools for the job: Cantabile is a super-powerful “container” to use plugins live, while a DAW is a production tool to combine audio and MIDI tracks, virtual instruments and plugins in order to produce songs.
Audacity is not a full DAW, more an audio editor - I see a number of people starting out with Audacity, because it’s simple and free, but as soon as they get to “real” production tasks, Audacity is too limited - they all switch to a “real” DAW sooner or later, which means re-learning a lot of skills.
So IMO, it’s better to start producing with a real DAW, because it will be able to keep up with you as your skills grow and the complexity of production tasks grows with them (insert and send effects, group tracks, buses, automation, sidechains, …).
If you really want to stick with connecting Cantabile and Audacity, take a look at Vincent Burel’s virtual audio cable - it allows you to take the output from one application (Cantabile) and connect it to the input of another application (Audacity). This way, you can record Cantabile’s output in Audacity.
