Using Sonar X1 Studio.
 
FX stopped working in the Master Bus.  The Master Bus meters show that it is receiving from the tracks, but the FX meters in the Master Bus are flat (reverb, boost 11) and I can't hear the effects being applied. 
 
On this current project, I have all the tracks going to the master bus, and the master bus goes to a Focusrite Scarlett 2i2.  The FX worked fine a few hours ago, but now.....nothing. 
 
Thanks.

Forgot to mention - I opened a few other projects and the FX/Master Bus works fine in those.  Its just my current project.

Something is definitely screwy, especially if you can hear your individual tracks but not the Fx in the bin.

 Is the whole Fx bin Bypassed?

What settings have you got on Boost 11? It won't do a thing until you increase the Drive above 0dB
Also check the obvious - is the Power button on?

Likewise with your reverb - a) is it switched on, b) is the wet parameter set above 0dB? (Assuming whatever reverb plug you're using has this - most do)

If you mute the Master Buss, does ALL sound stop?
If not then you've got one or more tracks going straight to your soundcard, bypassing the Master buss

Make sure the [F/X] button on the Control Bar isnt activated.  If it is it will be lit up Blue. Click it.

Can you post a screen shot of it?

Tried all of the advice above....except, "Is the whole FX bin bypassed?"  I don't know the answer to this.  Is there a button that bypasses all effects in the master bus? 

I have 25 tracks going to the master bus.  Is it possible that adding effects to 25 tracks is just too much for my computer to handle.  I doubt it since the project runs without pops, delays, or other indicators of a bogged down computer.

HA!!  Found it!  The bin bypassed switch was on.  Un-switched it - works fine.
