Using a Grid as Linnstrument

neauoire · 2019-07-12T02:28:15.682Z

I had some time this morning, give this a spin.
Let me know what you think!

Layout

G0#  A0   A0#  B0   E3   F3   F3#  G3   C6   C6#  D6   D6#  CY   CY#  DY   DY#   
E0   F0   F0#  G0   C3   C3#  D3   D3#  G5#  A5   A5#  B5   E8   F8   F8#  G8   
C0   C0#  D0   D0#  G2#  A2   A2#  B2   E5   F5   F5#  G5   C8   C8#  D8   D8# 
GZ#  AZ   AZ#  BZ   E2   F2   F2#  G2   C5   C5#  D5   D5#  G7#  A7   A7#  B7  
EZ   FZ   FZ#  GZ   C2   C2#  D2   D2#  G4#  A4   A4#  B4   E7   F7   F7#  G7  
CZ   CZ#  DZ   DZ#  G1#  A1   A1#  B1   E4   F4   F4#  G4   C7   C7#  D7   D7# 
GY#  AY   AY#  BY   E1   F1   F1#  G1   C4   C4#  D4   D4#  G6#  A6   A6#  B6  
EY   FY   FY#  GY   C1   C1#  D1   D1#  G3#  A3   A3#  B3   E6   F6   F6#  G6

So, 00 05 0A 0F would draw:

getting an error in terminal when trying

sudo npm install

seems to be a permissions issue

That’s weird, did you had this issue as well with the linnstrument?
Could you try sudo again?

Prnts · 2019-07-12T03:27:13.326Z

No problems with linnstrument all went smoothly when I did the npm install

neauoire · 2019-07-12T03:28:31.572Z

Does it work if you don’t use sudo?

Prnts · 2019-07-12T03:31:34.857Z

20 characters of no after just trying npm install

neauoire · 2019-07-12T03:32:55.351Z

I’m not sure why your computer won’t give you permissions to install this. Let’s see if someone else has that issue as I cannot reproduce it.

Prnts · 2019-07-12T03:42:18.518Z

I have a hunch that it may be an issue with the virtual modular program rack being installed. I’m going to try something.

**edit that wasn’t it. Tried on another machine which actually had a problem due to what I had mentioned above but it is still an issue on my main computer. So strange.

SOLVED
Apparently when I had installed linn I had made a mistake and installed to my home directory instead of the documents folder. So when I had just tried to to the rack install in the home folder it worked. Geez

neauoire · 2019-07-12T04:22:23.921Z

Happy to hear!
I’ve created a new thread dedicated to Rack.

kasselvania · 2019-08-02T15:57:45.178Z

Hey, I have finally had a chance to try out the linnstrument on a non-vari brightness monome. Thing’s look great. I only see the C notes, but that’s absolutely fine. That basically gives enough of a footprint to be able to use it.

Sorry it took me so damn long to try it out. Lots of work and travel, followed by brief stints fooling with the norns.

camckoy · 2022-04-11T18:28:03.264Z

Would this work on a 256? Would it only be the top or bottom half that would have the Linnstrument layout?

zebra · 2022-04-11T18:46:49.152Z

it is hardcoded foer 128x64 elements, and will probably work with the upper half of your 256.

at a quick glance, seems that it would only require these mapping tables to be updated:

github.com

neauoire/linn/blob/master/index.js#L16-L25

      
        
            const notes = [
              'F3', 'F3#', 'G3', 'G3#', 'A3', 'A3#', 'B3', 'C4', 'C4#', 'D4', 'D4#', 'E4', 'F4', 'F4#', 'G4', 'G4#',
              'C3', 'C3#', 'D3', 'D3#', 'E3', 'F3', 'F3#', 'G3', 'G3#', 'A3', 'A3#', 'B3', 'C4', 'C4#', 'D4', 'D4#',

            }

i didn’t spot anywhere else where row count was assummed but could have missed something.

the concept itself is pretty simple, just a list of notes that correspond to (x,y) locations, so might be simpler to apply it more directly in whatever environemnt (norns script, m4l patch etc)

camckoy · 2022-04-13T01:50:49.325Z

Thanks for this. I’ll give it a shot.

FLORINS · 2022-04-15T17:02:15.894Z

@neauoire Would love to try this out! I’m getting lots of npm WARN old lockfile and npm ERR! when I do the npm install. I can post the specifics if you like. Any suggestions for the novice coder - Thanks!

neauoire · 2022-04-15T19:00:11.686Z

It has been a long time since I’ve used NPM, but what happens if you simply delete the package-lock.json file?

tedpallas · 2022-05-23T06:15:30.062Z

has anyone gotten this to work on windows? i get this error, i wish i knew what to do to fix it:

MidiOutWinMM::openVirtualPort: cannot be implemented in Windows MM MIDI API!

Ben_F · 2022-05-23T07:33:51.336Z

Newbie here

Can tou explain to me how I can use this with norns ?

Does it work with neotreillis 128 grid ?

Molotov · 2022-05-23T09:09:25.898Z

for anyone getting errors on the
npm install, removing the package-lock.json file worked for me, thanks for the tip!

coreyr · 2022-08-28T21:40:31.628Z

Installed, setup and everything works great!

~~[Turned everything off, came back and using the directions:]~~
~~[## Whenever you want to use it]~~

type cd Documents/linn
type node index

~~[terminal threw an error:]~~
~~[ code: ‘MODULE_NOT_FOUND’]~~

EDIT: its all fine I was forgetting the “/linn” after cd documents

appa · 2023-01-23T04:05:58.522Z

Is anyone using Linnstrument in this way routinely? Is it worth it?
