Hey guys.  So lets say you have your guitar plugged into your amp as normal. And lets say you have some effects pedals such as overdrive delay chorus etc.  You can hear their sounds as you play.     OK...say you didnt have any effects pedals but you noticed that you have VST plug ins such as phaser, delay , reverb.      So .... instead of plugging the guitar into the amp as normal, you plug the guitar directly into your audio device (in my case an M Audio).   Now , can you play the guitar and also listen to the plug ins in real time?
Normally you would record a track and add in reverb etc later.    But could you play the guitar and hear an amp sim, reverb, phaser while you play?        Hope my question is making sense guys...thanks.    Xave

Yes. As long as you can lower your buffer enough there isn't significant and distracting delay

This shows using a midi foot controller to have stomp boxes and expression pedals.

hmm... sorry guys im not getting it.   My fault...Im not asking the question the right way.   Start again.
 
Plug your guitar directly into your audio device , play and record.  You now have a track with a clean guitar.  Now add in some plug in effects such as chorus.
Now... start again.   Plug in your guitar directly to the audio device.   Insert a chorus plug in into the track.
Can you now play the guitar and hear the chorus effect as you play?

You may have to freeze existing tracks if you have lots other FX active on other tracks to keep latency low.
Also select input echo, to right of record to hear the FX applied to your guitar.

Absolutely. 
 

Make sure you turn on input echo on the track.

Thanks guys..    Some good tips there.   This will save me buying guitar pedals only to find I'm not gone on their.   I'll download some plug ins first such as amp sims, reverb etc.  
Thanks again all :)

Not sure what version of Sonar you have, but you may have a number of existing FX-chains and amp sims you could work with already.
