Four independent loop slots that behave like a hardware loop station: record a phrase, close the loop at exactly the length you played, and layer overdubs on top without a seam. Keep the keepers by bouncing them onto a recorder track.
The looper listens to your microphone or audio interface, so start with Listen and wear headphones to keep the playback out of the microphone.
Tap Record on a slot and play your part. Tap the same button again, now labelled Stop & Loop, to close the loop at the length you played. It starts looping straight away.
While the loop plays, tap Overdub. It waits and starts exactly on the next loop boundary, so there is no seam, then keeps looping with the new layer baked in.
Choose a repeat count, or type a bar count into Fit Bars and press Calc to work it out from the loop's length and the tempo, then bounce the loop onto a recorder track.
Run a rhythm loop, a bass loop, a texture loop and a solo take at once, each with its own controls.
Overdubs start on the next loop boundary and never drift out of time.
Drop a layer in and out to build an arrangement live.
Work out how many repeats fill a given number of bars from the loop's actual length and the current tempo.
Make a loop a permanent part of the song on a recorder track.
Press 1 to 4 on the keyboard to trigger each slot, or map a MIDI footswitch to hands-free control.
Record a four-bar chord progression and solo over it. Loop a bass line, then play chords on top. Or build a three-layer texture, rhythm first and lead last, to practise arranging as you go. Because each slot is independent, you can keep one loop running while you re-record another.
Loops are also a good way to practise timing. Record a click-accurate phrase, then overdub the same phrase on top; any drift from the beat becomes obvious immediately.
Loop audio itself is not saved in a project file, so bounce anything you want to keep onto a recorder track before closing Fretnook. Once it is on a track it is saved with Save Project like any other recording, and you can edit, arrange and mix it in the recorder.
A looper is at its best when your hands are on the guitar. Fretnook accepts the number keys 1 to 4 for each slot, and it can learn a USB MIDI footswitch: press Learn beside an action, hit the pedal, and it is mapped. Setup steps are on the MIDI footswitch and USB interface page.
Fretnook is free and runs in your browser. Your microphone audio and recordings stay on your device.
