ZitatOnly real time bouncing will work with the Virus TI. Logic, Pro Tools and Cubase
users can choose the right settings straight away from the bounce dialogue
window. Ableton Live, FL Studio, Sonar and Digital Performer users need to rerecord
the Virus. Details on how to do that can be found in the respective tutorials.
Sonar does have a realtime bounce (audio export) and a realtime freeze (in fact it is the only host that has both, although Reaper has something similar)
