Display MoreWhat is it you think you can't do in the editor?
You can select from presets (the default ones or ones you create). You can also easily create your own folders to hold presets you might use frequently or maybe presets you modify.. You can add one of these to any slot you want, then you can edit the parameters in the editor. Keep in mind that any effect you use is really a preset. It's not required that you save them as presets, but you can if think they might use them elsewhere. Easiest way to save a preset is just to drag it from the editor to a folder somewhere in the Presets section.
So for example you could make a folder named Wha, then add any Wha presets that you might use to that folder. Then you can add any of those wha's to slot A (or any slot). You can just double click presets to try them out and see which you like best. Once added to your rig you can edit any of the wha parameters.
Same thing applies to distortions, cabinets, EQ's and so on.
Deep editing (like what's found with the settings button and rig button) are largely unsupported at present. You can't configure expression pedals, nor perform MIDI assignments, yet.
