What I’ve always found a little daunting with Podium is how to set up a basic mixer with 2 aux channels for reverb and echo.
I don’t know how long it has been since you’ve last tried Podium, but you can now specify the number of bus tracks you want in the new arrangement dialog.
Also how do you get a plugin (like Jamstix2) to turn into an audio track?
If you mean render the output to an audio file: Insert a bounce track in the Jamstix2 output track.
And how do you get the guitar track to trigger the “audio in” on the Jamstix track?
I’m not familiar with Jamstix, but if it has audio input, then there should be a Jamstix “in” mapping that you can assign on your guitar track.
Finally – have yo got ReWire on your roadmap?
I have features planned that will take a few months of work, and Rewire is currently not on that list.
