I have never been able to play electric guitar plugged straight into my audio interface and have input monitoring turned on (not that I try a lot). Despite the round-trip latency reported by SONAR, it feels like it must be 100ms. Completely unusable. So usually send an output from a DI box to a combo amp for monitoring what I play while recording the DI signal for use with TH2.
 
My old Mackie Onyx 400F finally died, and I got a PreSonus FireStudio Mobile today to replace it. Install/setup was painless. Using ASIO. Lowered buffer to 128 which is 8.6ms roundtrip. No weirdness playing projects, so 128 seems OK.
 
On a whim, I decided to try playing guitar plugged straight into the FSM with TH2 inserted as a plug-in. Still completely unusable. So I deleted TH2 and was listening to the direct guitar signal. Still totally unusable.
 
The thing is, if I run the TH2 standalone app, it works just fine. What am I doing wrong here (in X3)? This is supposed to be possible, isn't it? Running Win7 SP1 x64.
 
EDIT: If I create a brand new empty project and add one audio track it works OK, so it must be something in my project (or most/all of my projects).
 
Thanks!

Never mind. Figured it out. I'm fond of slapping a Waves L3 UltraMaximizer in the FX bin of the master output as it (or something like it) will eventually get used on the final mix. I fiddled with the PDC button in the toolbar but it had no effect. Deleting the L3 solved the problem.

No need to delete it - just hit E to bypass your effects

Any effect with significant lookahead (e.g., the TS-64) will increase latency. 

Turning off all effects kinda defeats the idea of playing/recording live through the Overloud TH2 guitar amp sim, but deleting the offending effect was easy enough. And when I saw that that fixed it, the reason was obvious: look-ahead limiter adds latency. Duh on my part...

Trust me on this - you're not alone. This sandbags a lot of people. Maybe effects should have a little symbol if they include lookahead that's over 2 ms.
