Looper for drone and arpeggios

Practically the same request as “Loops e.g. for drums and bass”, provides a little more insight

It would be great to have a looper. Let’s say it “records” what I play for 2 s or 5 s, and keeps looping that forever.

I personally would use this for vocal practice, while keeping a drone-like (e. g. Polysynth Pads) in the background.

A practical use case would also be an arpeggio. We can experiment with different melodies while the arpeggio runs in the background.
