grd


i’ve revisited my old supercollider code and rewrote in lua. it can do granular synthesis at rapid iterations or can sound like a music box at gentler speed. in any case it’s largely an autonomous thing.

documentation

the two parameters R and G can influence the process…

key3 start/stop
key2 page
enc1,2 params

requirements

norns

there’s a custom engine and a supercollider class. follow the steps below for installation.

installation

use maiden and find it from the community library. after installing type ;restart and enter.

installation (manually)

login via ssh then:
cd dust/code
git clone https://github.com/yotamorimoto/norns_grd.git
mv norns_grd grd
cd grd
git submodule init
git submodule update
~/norns/stop.sh
~/norns/start.sh

GRD should now show up on the SELECT menu.
enjoy.

known issues

the engine does not have the common ‘fixed number of voices’ architecture so choosing a very small ‘delta’ with large ‘duration’ can spawn quite a few nodes (a few hundreds or so). it may cause glitches for machines with limited capability. I’m working on the fix!

Does this require installing a new engine?

#3

It looks like it includes a new engine and some supporting classes, but at first glance seems self contained (no installation required on Norns, b/c Norns already scans the relevant locations for SC extension classes)

Indeed it does. Thanks for asking. It’s all contained in the github code. I will write in the description.

Right. The class is a small multi-sampled instrument. It is contained in the package and norns just compiles it automatically. But for the first time restarting of engine is necessary.

#6

Oooh this is really nice to sit and listen to!

my working install steps from ssh:

git clone git@github.com:yotamorimoto/norns_grd.git

mv norns_grd grd

cd grd

git submodule init

git submodule update

sleep norns then reboot

Thanks a lot! The norns side of thing is pretty new to me (though I’m with supercollider 20+ years). So i’m not sure of the standard way of installing but instead of sleep and rebooting I did norns/stop.sh and norns/start.sh (from the ssh). And that also worked fine.

quick method w/o rebooting is SYSTEM, RESTART which just restarts the norns software (including sc) instead of the whole os

thank you. Is it the same as ;restart in maiden? i don’t seem to have RESTART in my system menu. probably running an os behind.

#10

I am getting this when I launch NORNS_GRD/GRD. Any ideas?

I’ll check it later today. sorry about that!

ok. i added the steps of installation in my original post above. you’d better delete the previously installed folder. hope this will work!

worked great, thanks!

#14

Maybe that was a typo?

SYSTEM>RESET will restart everything, but it also resets a bunch of system settings to defaults (like MIX levels, some params, etc.)

from maiden you can do ;restart in both the Matron and SC tabs.

I want to give this script a try soon! :grin:

Ah, right… thanks for the that. then ;restart is easier. And a BIG thanks for the fates shield. so happy to have it!!

true, using the terminal isn’t the most friendly way, i must admit… i’ll have to check how this can be included in the maiden repository.

open a pull request against norns-community, adding your project’s description to community.json. (here’s an example.)

#19

not sure why, but doing the soft reset resulted with a “supercollider error” for me.

#20

pull request sent. did it work?
