Ok, here's the bare bones tech stuff: The Axe's Looper block only allows you to run one loop. This loop can be pretty long if you chose to run it in mono without Undo capability. I have decided though to run it in stereo with Undo capability (only one layer of Undo: cutting out everything you added during the last Overdub period). This choice is because I generally like to play the looper more like an instrument than like a recorder; so I keep changing the audio in that loop while playing beside the loop. Another fundamental limitation is that the Axe's Looper block can not calculate a tempo from the loop you catch (in order to run all effects you might be playing through at the calculated tempo setting). The workaround for this is (A) to make sure you start playing in the same tempo as the machine runs at (I use a Tap Tempo switch to make the machine follow my tempo) and (B) set the Looper block to "Quantise". Quantise means that in case you hit the Record switch early or late (both when starting the loop and when closing the loop) it moves the loop points, forcing the loop to line up with the machines internal global tempo (which is the tempo all those lovely "Eventide-killer" effects are running at). ---> Signal chain I use 9 sound patches that I switch between for nine "virtual dual-in-parallel effect chains" - All effects early in the chain. - Looper block late in the chain. - Reverb last - providing the "same room" for (1) amp/cab sound, (2) effects and (3) the Looper block. An important part of the effect chain, in all my patches, are two simple Delay blocks (one on each fretboard, as my current instrument is a dual-output instrument). One pedalboard switch instantly changes the length of the delay return: state X is 4th vs dotted 8th and state Y is 4 bars vs 3 bars. That way you can instantly catch your playing pre looper with the delays and have it come back a bit differently than you played it. This all happens before the Looper block, so it might get looped or not. When you switch between sound patches on the Axe the Looper block keeps playing back as if it was one machine, given every sound patch uses a Looper block with the same settings. Delay tails and reverb tails are also preserved when switching sound patch. Here's a list of the nine pedalboard switches I use to "play" the Looper block: 1. Record. 2. Half Speed 3. Overdub on/off. 4 Overdub, momentary switch. 5. Reverse loop. 6. A switch that circulates between four levels for Looper Feedback - 0%, 20%, 70% and 97% Feedback. (I also keep an expression pedal constantly connected to Looper block's Feedback) 7 Undo (undoes the entire last Overdub action). 8 Fade Out (or Fade In, depending on initial state). 9. Play/Stop (stops loop playback and always starts it again from the top. Can be used as momentary for instant retrigger of loop) The MIDI pedalboard I'm using is a Gordius Little Giant and I would guess that you need a pedal of that flexibility to get at all the parameters I'm listing above. Most parameters in the Axe have a unique MIDI #CC that they listen to and all you have to do is to pick your fav parameters and make your pedal/controller send the appropriate #CC's.
