Nice advice, beepster, thanx!
Will give it a go. I'm pleasantly surprised by GR.

Yeah... it's WAY better than the older versions of GR. I was quite pleased with it myself. Doesn't replace the real thing but you can get pretty darned close. If you got the Anderton vids with Sonar he does a section on really tweaking out amp sims (and he uses GR4) to make them sound even better. I believe it is in the second vid "The Next Level". There is also a text based description he wrote of the process over on SOS. Have fun... oh and be sure to read the GR manual. A lot of your questions might get answered there.

Sorry to dig up an old thread, but I made the mistake of not installing GR 4 when I installed Sonar X2 Producer (from a Cake Store download, not a DVD).
 
However I have tried to do the custom install to only select GR to install, but it is not on the list op selectable options, in fact it is not mentioned anywhere at all in the Custom Install dialogues.
 
Any ideas?
 
Thanks
