how are you doing that? All you can do is bypass or x/y between scenes, right? How do you change settings on the amp block between scenes?? You're only using one amp, right?
If you set up amp1 in scene1 with X/Y set to X, and you set up amp1 in scene2 with X/Y set to Y then scene 1 and 2 will retain those settings for X,Y within each scene. You can therefore have a clean delux reverb amp + applicable cab on scene "1X" and a recto amp + different applicable cab on scene "2Y". Once you are there, duplicate your scene "1X" into 2 scene variations - one scene with a light distortion pedal turned off and on with it turned on (clean scene, crunch scene). Similarly, divide you scene "2X" into two scene variations, one with distortion pedal / delay off, and one with them on (rhythm scene, lead scene). You now have 4 scenes for clean fender, crunchy fender, higain recto, higain recto lead all in one patch using only one amp/cab block. You could also achieve your clean/crunch, or higain/higain lead variations by attaching controllers to one or more of: drive/input level/boost/MV... on amp1 but since these controllers cannot vary across x/y or across scenes, you'll need to watch that they are set accordingly as you change scenes (would be nice to be able to have independent, or at least "bypassable" controllers across x/y and/or scenes). If your preferred tone absolutely requires 4 sets of different amp parameters that can't be varied with controllers or that you don't want to vary with controllers, then, in that case, you'll need to have 2 amp blocks.
I'm sure he meant Amp1 X clean, Amp 1 Y crunch, Amp 2 X rhythm, Amp 2 Y Lead
in the above example - only one amp/cab block in the patch.
When switching x / y you have a short gap.
I don't experience any gap.
How is that saving any cpu then? Am I missing something.
Amps and Cabs are 2 of the most cpu expensive block so using the scheme described above, you would save a lot of cpu space that can be used for effects ...
I think the CPU saving is from using only 1 cab block, in the previous example. But it's possible he doesn't know how scenes actually work, it wasn't really clear.
This scheme works for me and some others on the forum (see alarto above). Maybe there's some additional disadvantage I'm missing?
