Bub-Thanks for the comment. Really liking Guitar Rig. I am just too lazy to mess around with amps, effects, wires, miking, etc.... anymore. GR4 is pretty good and wide variety of sounds. I use a trick sometimes to give the illusion of miking by re-recording my GR4 performance with a mike, from my KRK monitors. Just add that track at a lower volume to add a little more dimension in some cases.
Tom- Thx
Morenoise/Rik- Good question. I always noticed when plugging my guitar directly into my RME with Guitar RIG in the FX bin that it sounded thin and weak when playing back. I think it has something to do with the phasing with the pickups and the FF800, or something. I already had the RIG Pedal so decided to try that out, it worked well so just started using it that way. I guess the Kontrol Rig is more forgiving than the RME when it comes to guitar pickups. Later I read an article with Craig Anderton where he was talking about digital artifacts and fizzy tones, and that using products like Guitar Rig with higher sample rates, (I use 96k) reduces the effects of those artifacts and gives a more analogue tone. The fizzy high, shrill stuff is that noise you find when sweeping across your EQ frequency range with a narrow Q and high boost.
So I didn't have enough horsepower on my DAW workstation to run Sonar and Guitar RIG at 96k so I just installed Guitar Rig on a spare laptop I had. The laptop runs only Guitar Rig, with the Kontrol Pedal sample rate set to 96k. The Kontrol Pedal then goes into my RME FF800. I have Sonar/RME set to 48K. As I am just recording audio from the Kontrol into the RME FF800, the sample rates do not need to match. I found the result to be OK so have just stuck with it. Also, I like to hear what I am playing in real time. I know you can do that with Input Echo but the latency doesn't work for me. I like to hear the entire context of the music behind the parts and when I set latency low enough to not have any noticeable delay, things start to crackle and pop. This was just a clean way to do it. Hope that answers your question.
BTW - The Anderton info regarding amp sim sample rates is located at link below.
