The norns is a raspberry pi-based sound computer from monome. I currently have the norns shield as part of my music setup.
Developing norns supercollider engines locally
- Pull the norns repository
- Make symbolic links from norns sc folders -> SuperCollider Extensions folder:
ln -s ~/Developer/monome/norns/sc/core ~/Library/Application\ Support/SuperCollider/Extensions/monome-norns-core
ln -s ~/Developer/monome/norns/sc/engines ~/Library/Application\ Support/SuperCollider/Extensions/monome-norns-engines
ln -s ~/Developer/monome/norns/sc/ugens ~/Library/Application\ Support/SuperCollider/Extensions/monome-norns-ugens
Make symlinks to Norns community repos e.g.
ln -s ~/Developer/monome/we/ ~/Library/Application\ Support/SuperCollider/Extensions/monome-we
- Make symlinks for custom engine development
ln -s ~/Developer/MyNornsMachines/ ~/Library/Application\ Support/SuperCollider/Extensions/MyNornsMachines
I can send commands to the engine using something like
n = NetAddr.localAddr; n.sendMsg('/engine/load/name', 'Thunk'); n.sendMsg('/command/load_sample', 1, 'sample.wav'); n.sendMsg('/command/note_on', 1, 1, 1.0, 1.0);
Using Digitakt as a soundcard
You can use the connecto script to connect Audio over USB to the Digitakt. This works great, but seems to use a little more CPU. So to make the change more “permanent” (you can always undo these changes and reboot of course) I found this suggestion on lines:
Change line in
ExecStart=/usr/bin/jackd -R -P 95 -d alsa -d hw:sndrpimonome -r 48000 -n 3 -p 128 -S -s
ExecStart=/usr/bin/jackd -R -P 95 -d alsa -d hw:1 -r 48000 -n 3 -p 128 -S -s
and then reboot (or
sudo systemctl restart norns.target). The digitakt needs to be connected and powered on when the norns boots for this to work.
