Abstract

Yggdrasil is a norns cyberdeck tracker — an instrument designed to be performed with a keyboard only. "Slots" are the nucleic acids of Yggdrasil, while "commands" and "interactions" are the twin helixes of the human-machine interface. Toggling Y Mode remaps the alpha-numerics, unlocking expressive performance gestures. Capital letters are not used and modifier keys only sparingly. Where other languages use may use commas or parenthesis, Yggdrasil favors the ; character for its position under the little finger: economic, ergonomic, exegesis.

Neurotically focused on their endless descent, slots are stacked into tracks of different heights, like so many stalactites reaching into the terminal darkness below. Slots can contain up to one each of: note, sample, velocity, and phenomenon. Slots contain two "macro control" values that range from 0 - 99. Phenomena allow for exotic events such as randomizers, "goto" events, and directional toggles.

Commands are built from the letters, numbers, and symbols that appear in the terminal as you type. Commands let you do things like create musical patterns, change notes, control playback, adjust tempo, and route tracks to different MIDI channels.

Commands that start with two numbers operate on a single slot.

Commands that start with one number operate on an entire track.

Commands that do not start with a number operate across all tracks.

Signatures Examples
X Y COMMAND;VALUE 2 4 arp;2
X COMMAND;VALUE 1 arp;2
COMMAND;VALUE unmute

These leading numbers correspond to X and Y coordinates, respectively. Most commands have both verbose and terse invocations. For example arpeggios can be invoked not only with arpeggio but also with arp and a. All commands are executed with the / return / enter key.

Interactions are simply "everything else" you do with the keyboard; our silent movements through Yggdrasil's data streams. While some interactions technically manipulate sound under certain conditions (such as mod + backspace to clear a selected slot), most are simply affordances for navigation — things like toggling views, dismissing messages, or paging through through command history. ctrl, alt, opt, and cmd are functionally identical and collectively referred to as mod.

Let's go.

Musical Commands

Note

Set a slot’s MIDI value. Accepts YGG notation.

Signatures

X Y MIDI_NOTE

X Y YGG_NOTE

Examples

4 3 72

4 3 c5

Velocity

Set a slot’s velocity value. Unlike most other systems, velocity is mixed with track level to produce a final result. For example, a slot with a velocity of 70 on a track with a level of 50% would produce a final velocity of 35. The exception to this rule is the crow clade, which can use neither velocity nor track level information.

Signatures

X Y velocity;VALUE

Chord

Paint a chord horizontally starting from X Y. Automatically append tracks and rows if needed. Any size chord can be built. An extensive chord library available or precision chords can be entered with MIDI values. Chords default to octave 4. Append a semicolon followed by an integer to set an octave: 1 1 c;cmin;6

Mixer Commands

Level

Set the level of a track. Valid levels are 0% to 100%. Levels are linear.

Unlike most other systems, velocity is mixed with track level to produce a final result. For example, a slot with a velocity of 70 on a track with a level of 50% would produce a final velocity of 35. The exception to this rule is the crow clade, which can use neither velocity nor track level information. See Y Mode interactions, too.

  • midi
  • ypc
  • crow

Synth

Set the track’s synth voice and macro control levels. Use synth;enc to toggle takeover mode for macro controls with norns encoders 2 and 3.

The Yggdrasil synth has three different polyphonic voices. You can use all three at once, across any number of tracks. Use either name or their number in combination with synth;voice; to set.

# Name Description
1 PPM The norns classic, with parameters pared down to the basics.
2 Rikki All edges, angular digital angst. Fuzzy nudges through shimmering waves of banshee cries through broken glass.

YPC

Set a global sample bank and load samples into tracks and slots. Yggdrasil can access one bank at a time, but a bank can contain any number of samples. Slots contain can contain up to one sample, but tracks can contain any number of slots (each with unique samples.) “Banks” located at /dust/audio/yggdrasil/banks/.

Yggdrasil ships with a default factory bank.

If a filename has frequency information at the end, like your_sample_name_440hz.wav, Yggdrasil will repitch intelligently. If the filename does not have frequency information at the end, a default of 440hz will be used. Once a sample is loaded into a slot, a note value also needs to be set. A common technique is to use x ypc;l;your_sample_name_440hz.wav and then use x arp.

Shadow / Unshadow

Set a track to “shadow” another’s clade and clade attributes. For example, let Track 1 be a MIDI clade set to channel 16 and device 4. By invoking 2 shadow;1, Track 2 would shadow Track 1. Its clade would be set to MIDI, its channel to 16, and device to 4. Should any of these attributes on Track 1 change, they would also change on Track 2.

Shadowed attributes are: clade, synth voice, MIDI channel, MIDI device, crow pair, Just Friends mode. Tracks can shadow other shadowed tracks.

Glossary

Clade

The taxonomic principal organizing tracks into one of: synth, MIDI, YPC, or crow.

Phenomenon

An event, action, or piece of logic associated with a slot. Slots can contain up to one phenomenon.

Y Mode

When toggled on, alpha-numeric character input to the buffer is broken and keys take on new functionality. This behavior is comparable to to vim’s normal/default mode.

YGG Notation

YGG notation is like IPN but faster to type - there are no capitals and the # sign is replaced with s. So C#4 becomes cs4. Yggdrasil saves data in YGG. YGG is also an acceptable input format for any note command.

YPC

“Yggdrasil Production Center” - the sampler/softcut system for Yggdrasil. History. The YPC uses an intelligent “first in, first out, round robin” algorithm to play samples. Softcut (the internal sampler engine in norns) has six voices, so if Yggdrasil is instructed to play 7 samples at once, only the first 6 will fire. Once the first sample is complete, another sample will be available. The YPC can support any number of banks, each with any number of samples. YPC can intelligently repitch samples.

Tracker Planes


Imagine the tracker with five planes: notes, samples, macros, velocities, and phenomena. With the view command you can toggle each plane on and off.

  • Note: stores note data. This can be viewed as IPN, YGG, MIDI, or frequency.
  • YPC: stores samples name.
  • Macro: stores “macro controls” of the synth. Each synth voice has two macro controls with values that range from 0 - 99.
  • Velocity: stores velocity data.
  • Phenomena: stores up to one phenomenon.

Focus, Select & Clear


Use mod + , , , and to to change focus. Press to select and backspace / delete to clear. Use shift to move in increments of 10. Note , backspace, and shift are also Y Mode interactions.

Y Mode Focus, Select & Clear


While in Y Mode, use h, j, k, and l to to change focus. Press to select and backspace / delete to clear. Use shift to move in increments of 10. Note , backspace, and shift are also eternal interactions.

Assignments and &&


You can assign any arbitrary text to variables. This text can be a fully valid command or a mere fragment… Perhaps a motif like 60;62;65?

Valid variables are constructed with the dollar sign ($) followed by a positive integer.

Once assigned, any command containing these will “expand” the first time you press .

Chain commands together for rapid execution with &&.

startup.txt


Automatically execute any number of commands on startup by placing a file at /dust/data/yggdrasil/routines/startup.txt. Each command goes on a new line.

Level


While in Y Mode, increment and decrement selected track levels by 1% with [ and ]. Hold shift to increment by 10%.

Select Track(s)


While in Y Mode, the number keys instantly select the corresponding track. With a track selected, hold shift and press another number to select a range of tracks.

Mixer


While in Y Mode, use q, w, and e to unmute, unsolo, and enable selected tracks respectively. Use a, s, and d to mute, solo, and disable tracks respectively. Remember: s olo, e nable, d isable!

Modifier Keys


ctrl, alt, opt, and cmd and all do the same thing. Collectively, these keys are simply mod. Let there be peace among the kingdoms.

Clear Values


With slots or tracks selected, hold mod and press backspace / delete to clear all values.

Cut, Copy & Paste


Cut, copy, and paste selected tracks and slots. It works just like your favorite spreadsheet program. Cutting and copying entire tracks will also pickup track attributes such as level, clade, direction, and so on. Interactions are the same in Y Mode.

Y Mode Off


Toggle Y Mode off the Y key. (This is to support keyboards that do not have caps lock.)

Switch Pages


Switch pages with tab. The pages are Tracker, Mixer, and Clades.

Toggle Y Mode


Toggle Y Mode on and off with caps lock.

Control via REPL


In the REPL, you can execute any Yggdrasil commands with cmd("YOUR COMMAND STRING").
