Norns: help

voidstate · 2020-02-13T23:41:38.000Z

Hey everyone, I’ve been delving into some droney depths lately and just wondered what scripts people are using to create drones with their Norns.

I’ve found the new wrms script provides some great results when fed through effects pedals.

Check out this softcut study, it doesn’t take much tweaking from the original starting point to get into really interesting droney spaces!

I have a Logidy midi pedal that doesn’t seem to want to connect. I get this in REPL:

“ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC1D0 failed: No such device
failed to open alsa device hw:1,0,0
dev_list_add: error allocating device data”

any ideas?

Specs say it’s a “ USB 2.0 compliant composite device“ with midi and HID. This might be wrenching up device recognition

Checking dmesg over ssh after you attach the device might give a little more data for debugging.

is there a general consensus re the usefulness of HID vs MIDI for footswitch controllers? Trying to set up my norns as essentially a guitar pedal but running into weirdness with HID data.

Hey folks.

I’m playing around with a Norns for the first time, and I’m interested in being able to route distinct signals to each of the four outputs (Stereo Headphone and two 1/4’ outputs). Is that possible? Or is the headphone signal always tied to the two main outputs?

I’ve been following these tutorials:

Norns: tutorial Monome

Tutorial This is a crash-course tutorial to get started with the sound computer Norns, follow the discussion here. If you would like to contribute, visit the repository. Connection You need to get the device online and accessible to your WIFI network. Add your router details to the device, in WIFI > ADD. Once the device is online, the IP field will display the Norns’s IP, example 192.168.128.109. [image] To edit code(IDE), open Maiden by going http://norns.local/ in your browser. To tran…

It seems like the CroneAudioContext defines the output to be stereo here:

github.com

monome/norns/blob/master/sc/core/CroneAudioContext.sc#L46


		xg = Group.after(ig);
		og = Group.after(xg);


		//---- busses


		// input 2xmono, output stereo, seems like a "normal" arrangement (?)
		in_b = Array.fill(2, { Bus.audio(server, 1); });
		//out_b = Bus.audio(server, 2);


		// send output directly to jack client ports
		out_b = Bus.new('audio', 0, 2);


		postln("AudioContext: in_b[0] index: " ++ in_b[0].index);
		postln("AudioContext: in_b[1] index: " ++ in_b[1].index);
		postln("AudioContext: out_b index (stereo): " ++ out_b.index);


		amp_in_b = Array.fill(2, { Bus.control(server, 1); });
		amp_out_b = Array.fill(2, { Bus.control(server, 1); });


		// each pitch bus is 2 channels:  [freq, clarity]
		pitch_in_b = Array.fill(2, { Bus.control(server, 2); });

Do I need to write a new AudioContext that defines a quadraphonic output? Is that even possible?

Looks like it is appearing as both:

I have this same midi controller! It would be great to get it working with norns

I think you just signed up for this task

I am totally into helping! Also, I know nothing of the inner-workings lol Super down for trying things if you have some ideas tho

edit: fwiw, here is the (hopefully) relevant bit of my dmesg output. ( I used dmesg | grep -i usb)

another Q

(learning to code in general)

in the following example, can someone explain how g = grid.connect() works?

is g.key the same as grid.connect.key?

is there a step in the tutorials that I missed that addresses this?

g = grid.connect()

g.key = function(x,y,z)
  if z == 1 then
    steps[x] = y
    grid_redraw()
  end
end

bob_ross · 2020-02-16T00:26:16.001Z

+1 for getting the UMI3 working

ground_state · 2020-02-16T00:35:12.330Z

Back-of-the-envelope (others please feel free to chime in):

grid is a norns built-in. grid.connect returns a grid object corresponding to the first grid found by the system (pro tip: you can use multiple grids by e.g. g1 = grid.connect(1); ‘1’ is the default).
g.key has to be a function, and, if defined, is an override of grid's default key method (which is just a stub, IIRC).

no it’s not possible. norns has stereo output. the headphone output is the same analog signal as the main outs, with an extra gain stage.

Hello I’m having trouble accessing maiden from my WiFi
and the internet works fine
I’m wondering what I can do thanks

Justmat · 2020-02-16T18:11:02.127Z

have you connected your norns to your wifi? Here is a link to the wifi troubleshooting page in the docs

Duksos · 2020-02-16T18:18:13.995Z

Yes it was working fine forever
I brought it on vacation for a few days and I cannot connect anymore
I tried forgetting network and unplugging dongle
I also tried reset
I’m exhausting my options

dan_derks · 2020-02-16T18:37:10.755Z

dang, that is always super frustrating :\

how did the drivers + USB-UART steps go? feel free to email help@monome.org for direct support, as well
please include:

Whether your nub was able to successfully connect with a non-norns computer
Screenshots of the terminal screens in step 4
Your router config (WPA, WEP, etc)

Duksos · 2020-02-16T20:13:01.865Z

Ok I’m in terminal what do you need a picture of
