I can see some of the benefits but a couple of things concern me:
- Performance in a daw won’t be as strong as ‘bare-metal’ C3. I use Reaper and even though it’s claimed to be one of the best cpu performers, maybe that’s for daw scenarios but I’ve found that that doesn’t apply to live setups. For complex setups live tweaking could stutter or lag when working with C3vst even though the live version was joyous.
- Automation parameters will be hidden in C3vst and would have to be exposed to the daw.
As an alternative, I’d prefer to see C3 increase it’s userbase by adding functionality like midi looping, piano roll editor and vst parameter recording/automation.
(@brad, it was great to see your developing piz’s work. His awesome but buggy midi-looper is also open-source
