 the line-in audio is fed into a delay loop for a duration of one quarter note, so it automatically becomes quantized to the `bpm` (ENC1). the amount of delay can be dialed in with `level` (ENC2) and `feedback` (K1+ENC2).

 the delay loop is randomly time shifted based on the probability from the `spin` parameter (ENC3). the audio from the delay loop is then fed into a second delay loop that is also time shifted and panned randomly.

 this would not have been possible without the stellar [softcut tutorial](https://monome.org/docs/norns/softcut/) and inspiration of randomizing speed shifts from [bounds](https://llllllll.co/t/bounds/23336).
