Latency Question X1 (SOLVED)

I have project with an acoustic guitar track, a vocal track and have 5 tracks of drums through Session Drummer. No problems.

I want to add a bass track and the latency goes crazy - unplayable. It seems there's so few tracks and load that the latency shouldn't change but the bass is so delayed as to be useless.

Here's my Audio set-up. I can play many many soft synths without and latency but I don't get this. Any help?

Even FXs on instruments can cause that too. But it is strange that you can play a VSTi. Do you have an FX on the bass? If so, do you have Sonar's input monitoring turned on for the bass track while recording?

Hi guys.  Can you describe this a little more in detail, and if you have any theories on how this can happen, internally, I mean.

Thanks.

For me it was having the FX on Subgroup Buses. It sucks to have to disable them but for recording it's no big thing. I didn't have to remove them just bypass/disable them.

I tried that button Middleman but no effect.

Plug-ins that require delay compensation (PDC) because of extra buffers they use for processing will cause all existing tracks and input monitored audio to be delayed to match the delay on the track being processed so that everything plays back in sync. Usually removing an effect is enough to reset the latency. If not, cycling the audio engine on and off should do the trick.

Thanks brundlefly,

Yeah I have so much learn. I found that with this simple track I could add FX like Sonitus compressor, reverb, the Vocal Strip and a couple others and it wasn't until I added the Linear 64 EQ that I got that latency. The very cool thing I also discovered was that simply clicking the FX button on the 'Mix' module disables all the FX so I can record without latency then hear it back with all FX by re-clicking the FX button on the Mix module..
