Can you explain more and detail how you plug everything in and how you set your block's up and if you ue other external hardware
If you are referring to me...no blocks needed (blocks would be needed if i wanted to use effects with the GR-20 or enhance the sound etc, not my case).
An empty preset (meaning the only thing is in there is a line/virtual cable straight straight from IN to OUT) is enough. Only thing i set (depending on the GR-20 sound i use at that time) is the level of the preset to get the wanted recording level(from AxeFXII's menu, "LAYOUT"-->"OUT" and i set the "Main Level" accordingly).
No blocks at all, that's the case that the Axe has only an "audio interface" role so the only purposes of the Axe are :
a)to listen what i play via the Axe-related gear (not seperate gear for the GR-20)
b)and the most important to me, to take the GR sound, convert it to 48Khz/24bit and send it to my daw/pc via usb.
Connections are simple...the GR-20 is 24/7 connected to the Axe like this: OUTPUT MONO(R) of the GR-20 to AxeFXII's rear INPUT1 (L/MONO).
When i select the "Midi" (as i have named it) preset i first must go to "I/O"-->"Audio" and change the "Input 1 Left Select" from "Front" to "Rear" and that's all (of course i have to remember to set it back to "Front" if i need to play/record guitars/bass).
The results are great (for my taste at least) the only thing i should really do is to back off a little bit GR-20's level because i have it cranked and i bet it inroduces a bit of noise (noticed it only in full silence, neither the REAPER's nor the Focusrite Mixer's indicators can capture it so it is mild but i can hear it and i know it's there).
