Zellen is currently not in active development, since I do not own a Norns anymore. If anyone wants to take over, feel free to fork the repository and create a new thread for it in the lines library. If you do so, send me a message on lines and I will happily link your new repository here and in the old lines thread.

A sequencer for Monome norns based on Conway's Game of Life.

• Grid: enter/modify cell pattern
• KEY2: play/pause current generation (semi-manual mode), advance sequence (manual mode), play/pause sequence (automatic mode)
• KEY3: advance generation
• hold KEY1 and press KEY3: erase the board
• ENC1: set speed (bpm)
• ENC2: set play mode (see below)
• ENC3: set play direction (see below)
• hold KEY3 + ENC3: time jog

Set the play mode with ENC2.

• reborn (default): Play a note for every cell that was born or reborn (= has exactly three neighbors), regardless of the previous state of the cell
• born: Play a note for every cell that was born (has exactly three neighbors and was not alive in the previous generation)
• ghost: Play a note for every cell that is dying(has less than two or more than three neighbors). Ghost notes can have a different pitch! (See the "ghost offset" setting in the parameters screen.)

Set the play direction with ENC3.

• up: Cells on grid are played from top left (lowest note) to bottom right (highest note).
• down: Cells on grid are played from bottom right (highest note) to top left (lowest note).
• random: Cells are played in random order. The randomized order will be stable for a generation and will be re-randomized for every new generation.
• drunken up: Like up, but decides for each step randomly if it goes up or down.
• drunken down: Like down, but decides for each step randomly if it goes up or down.

Set the sequencing mode in the parameters screen. Default is semi-automatic.

• manual: Press KEY2 to play the next step in the sequence for a single generation.
• semi-automatic: Plays the sequence for a single generation (and loops it if "loop seq in semi-auto mode" is enabled (default)).
• automatic: Like semi-automatic, but automatically calculates the next generation and plays it.

Zellen supports CV out via Crow. Crow CV output can be configured in Norns's parameters menu.

Crow configuration for Zellen:

• Input 1: Clock
• Input 2: CV offset
• Output 1: CV
• Output 2: Trigger
• Output 3: CV 2
• Output 4: Clock

CV offset (input 2) can be set to pre or post quantization in the parameters menu.

CV 2 is, just like the main sequence, a CV derived from the current play position on the board. The CV can be calculated with these methods (configurable in the parameters menu):

• x/y (default)
• x%y
• x+y (same as the main sequence)

Zellen supports playing notes on Mannequins Just Friends via Crow and a ii connection. The note value can be determined with the same methods as the CV 2 value for Crow (configurable in the parameters menu).

Set the MIDI channel (default: 1), MIDI velocity (default: 100), and MIDI clock in the parameters screen.

There is lots more to discover in the parameters screen, like root note, scale, and ghost offset.
