Analog heat with ableton live question

I am going to connect the analog hit to the Ableton Live by usb and apply fx to each track without an audio interface.

how can i set up?

1.Preferences in out ?
2.Analog Heat vst Audio Track or Medium Track? in-out setup method

I would appreciate your reply

the Heat IS an audio interface!

ableton preferences -> audio in/out -> select Heat.

i don’t use the vst functionality at all, so I can’t help you there. I just send audio to the Heat and record what comes back.

i am typically using external gear into the Heat and then into Ableton.
