d is for distortion, decimation, and destruction… or whatever

quick start

what’s happening?

d is made up of two parts: an engine providing bit crushing and sample rate reduction as well as tape style distortion/saturation, and a randomized control matrix.

the main screen is a lot to take in at first, but is pretty simple once you’re in the know. size and brightness of screen elements reflect the state of the engine. the elements are:

turn encoders 1/2/3 to change the engine parameters in varying amounts, according to the control matrix.

the matrix


each time you launch d the control matrix is randomized, so encoders 1/2/3 won’t always react the same way. this adds lots of variation in the sounds produced and leads one to find sweetspots. learn how to save and recall sweetspots below.

in addition to the encoders and matrix, you can perform some special actions using the norns keys.

nice numbers


pressing and holding key1 enters command mode. use keys 2/3 to input numbers. releasing key1 will input the command.

note, the first two numbers are the same for related commands:

(22 - reset)

(23 - set sweetspots)

(33 - change screen view)
