but I just managed to freeze and crash Reason, trying to
duplicate the Main Mix audio coming from the insert Main FX
and sending it to an audio channel through an input device...
like the Vocoder for example... without managing to record anything...
Audio track out was sent to a muted ghost bus, so in THEORY, no audio feedback
should have happened that could have crashed Reason...

I'm obviously not trying to use an external Audio recorder method, like
an Audacity setup with virtual cables, which would be the simplest way
to do it... is it even possible without breaking Reason???
Yesterday I recorded a full track, but I had to record all single channels,
and then I could get the main Mix rec afterwards, with the Bounce...
It's the Main Mix channel the difficult part here, to record it live...
It's the same thing as recording every channel and then get the Bounce mix export,
but with less steps in between basically.
