I have used mine both as 3 stand alone pedals and multiple pedals combined into patches. It kind of depends on the band.
I'm in a fairly loose pub covers band and it's fun to have different effects and use them on the fly however I fancy.
Depping in a more formal function band I will load up the entire set, each patch labelled with each song title in set order and just move through a patch at a time.
If one song calls for something different under a solo or wotnot I will copy the main patch tweak it for whatever the change is save the tweaked patch adjacent to the original then just go up to it as and when the song calls for it. That way I don't have to think just keep pressing the button to call up the next patch as and when needed.
Labelling patches is important as it ensures I know where I am if, say the box gets stomped accidentally.
When I use it as 3 stand alone pedals I can of course choose another three, six, nine whatever, but six is my maximum for ease. 'Patch' A1 might have distortion, chorus, compressor , A2 flanger, synth, compressor. That way if just one song has synth on it I go back out of home into bank, up to A2, out of bank and back to home. I can keep my compressor on throughout the gig but have that synth and flanger ready for that one song.
The change sounds fiddly but in reality doing it between songs takes less time than a guitarist uses to check themselves in the mirror.
