Nice and nice demo, very soothing.

How did you midi sync the cat though?

By using a CAT-5 cable ?

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, macro, velocity, and phenomenon. 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. Typically, commands will do things like change notes, control playback, or adjust tempo. Yet other commands will let you copy entire tracks, route notes to different MIDI channels, or even create musical patterns.

Not yet, but it will be soon!

installing this late tonight to have a go. unbelievably excited by the aesthetic, and I have a very appropriate keyboard for this purpose.

+++ the tiny animation when commands are confirmed

lovely interface design

I don’t know if my brain will take in the information it needs to make Yggdrasil music tonight, but I’m sure going to try. Big thanks for the docs page, this looks deep!

EDIT: got it up and running last night! While I would not call what I was doing music, yggdrasil certainly makes musical gestures attainable with the chord and arp entries.

hi! can’t wait to try it but so far on my norns shield any attempt to press enter after entering any command on any of my two keyboards results in this in REPL:

lua: /home/we/dust/code/Yggdrasil/lib/runner.lua:13: attempt to call a nil value (global 'debug_interpreter')
stack traceback:
	/home/we/dust/code/Yggdrasil/lib/runner.lua:13: in method 'run'
	/home/we/dust/code/Yggdrasil/lib/buffer.lua:14: in method 'execute'
	/home/we/dust/code/Yggdrasil/lib/keyboard.lua:95: in field 'event'
	/home/we/norns/lua/core/hid.lua:149: in function </home/we/norns/lua/core/hid.lua:139>

and the command is not executed (cursor just stays after the command). keyboards are Apple wired keyboard with numpad and a mechanical 60% that i’m normally using with teletype.

thanks! i tried restarting, cold rebooting, uninstalling / reinstalling etc.
running latest norns software.

woah sorry about that. that’s a dev function we had in there for debugging. i just pushed a fix. please update and let me know if that fixes it. (i’m really sorry for the trouble. sloppy qa on my part.)

drop these files into /dust/data/yggdrasil/tracks
load them with 1 load love-lead.txt, 2 load love-bass.txt, 3 load love-saw.txt.

tyleretters · November 9, 2020, 3:27am

very odd. i just pushed another fix.

also, what version of norns are you running?

trickyflemming · November 9, 2020, 3:30am

Thanks! That just fixed it for me as well. I’m on the 10/29 update using a Norns Shield.

That was a hell of a bootup screen. Looking forward to diving into this later in the week.

joe_biomassa · November 9, 2020, 3:30am

and it works now! thanks!
latest version of norns (shield).

tyleretters · November 9, 2020, 3:39am

report back!! i want to hear what you make!!
