ì don't have the Anagram, but from my experience with the HX Stomp and by reading Anagram's doc, I think it take a little time to get used to 3 switches, but you should be able to meet your goals:
- Each preset is the equivalent of a full pedalboard, where you can select the pedals (blocks) you want to use, but in practice, you would use each preset for one song or for a few songs. You mustn't change preset in the middle of a song (bacause changing preset cause a short silence, as the pedal needs time to load blocks in its memory). So let's say that preset 1 is for your songs 1, 2, 7 and 9 or your set lits, preset 2 is for songs 3 and 5, etc.
- In Stomp mode, each switch lets you turn on and off pedals, so it's very close to the experience of a standard pedalboard, but you can assign several pedals to each switch, so you can control more pedals at the same time, reducing the "FX dance". For example, switch 1 turns on/off the octaver and distortion, switch 2 turns on/off the chorus and delay, etc.
- When you are un Stomp mode, you can still change preset by pressing switches 1+2 (previous preset) and 2+3 (next preset). So you don't have to bend over to the anagram to touch the screen between songs. But you have to organise the order of the presets in a way that is convenient for your set list, in order to avoid pressing multiple time the footswitches between each song to get to the right preset.
- In Scene mode, it's a little bit more powerful than Stomp mode: you have 3 scenss, one for each footswitch. Think the scens as "verse", "chorus" and "bridge". In each scene, you not only decide witch pedal (block) you turn on and off, but you can also change all the parameters. For example, a light gain on the overdrive for the verse, and a higher gain for the chorus.
- In Scene mode, you can also change preset by pressing switches 1+2 and 2+3 the same way
- In theory, you can alternate between Stomp mode and Scene mode depending on the songs and presets, but it's easier to use the same mode during all the gig in my experience.
It's possible to re-order the preset on the pedal before each gig, to match the set list, but in practice, this operation is faster and easier to do with a external editor (Mac or PC computer, phone or tablet). It's OK because you do this before the gig, at home, when you know the set list. There's no external editor for the Anagram yet, it should be offered in a next update, but it's always possible to re-order presets on the pedal directly in the meantime.
