Stacking layers live

The principle, and why it's hard

Live looping fits in one sentence: you play a bar, it starts going around, you play another one over it. Repeat until it stands up.

What makes it hard is that there's no second chance inside a take. The first layer becomes the metronome for every layer after it. If it's slightly early, everything stacked on top is early too, and that can't be repaired later — or if it is, it isn't looping anymore, it's editing.

Ableton Live holds the loops

Live keeps each layer in its own clip and cycles them together. The tempo is set before starting, which keeps the layers aligned with each other however long the session runs.

The Push instead of a pedal

The usual answer is a looper pedal on the floor. The Push does the same job with pads, under the fingers.

It sounds like a detail and it isn't. A pedal needs a foot, so a weight shift, at exactly the moment you should be still. Pads fire from a hand that leaves the neck for half a second. In practice you can drop a layer in between two bars instead of waiting for the end of a phrase — and that changes what you're able to write.

What you hear in a clip

The layers come in an order, and that order is spelled out on each clip's page. Rhythm guitar, then bass, then an arpeggio, then a melody. Each one was played over the previous ones, in a single pass.

It isn't a reconstruction: it's the real order in which the loop was built.
