I'll try and answer this.

Your piping the master out of the source track complete with all effects 
to Jamin (try hearing just the master outs, are the effects on there 

You need to be sure what your monitoring, ie: are you hearing the right 

I normaly run jamin outputs to 2 extra inputs on my mixer to be sure 
that what I hear is what is going to disk.
Jamin will allow you to output to multiple outputs, you must hear what 
the new tracks are 'hearing'

Ok so you have:
tk 1 source music Left
tk 2   "      "   Right
These two tracks have effects on them going to master out (on the master 

Are you running these two tracks into jamin and bypassing the master?

Make sure your hearing the final mix and not just the source through Jamin.

Hope this helps.
