They will be recorded/printed on the aux track with the above settings. However, most of the usual reasons to do this don't apply because the same raw audio still hits the converters. In the digital domain it doesn't matter at what time the processing occurs.

Contrary to what some are claiming on this thread, the FX can be recorded if you have Platinum. Perhaps this is not the case for a lower level of Sonar but it sure works if you have the latest version of Platinum and have it up-to-date like I do. I just did some vocal recording with the harsh 2K reduced by about 10 db on track 1 and it recorded that reduced version onto the AUX track (track 2) and it came out nice. I know my voice is harsh in that range so why not fix it before it needs fixed? It's especially harsh when I sing the "Eee" sound which is in many songs. Now it's not so harsh and I don't need to tweak it much at all. A real time-saver.
 
Also I experimented with the TH3 guitar plugin and it recorded the FX on the AUX track without any glitches, and of course, you can also simultaneously record the "dry" signal as well. Thanx Sonar!

Delete the fx, and the fx processing will be removed.
 
Both Sander and Jonsey are on Platinum (see Jonsey's signature). I am on Platinum too.
 
Remove direct monitoring, to prevent phasing (from latency)
Add an FX to the bin (Say reverb to make the singer feel comfortable)
Record the take.
 
The Printed take sounds like it has reverb, because playback will use the reverb from the bin. Delete the reverb, and you'll hear the printed track without the reverb. Which is cool, because the reverb to make the singer happy, may not be the final reverb you then use.
