Many thanks!

Will this run at the same time as MLR Grids?

#15

Basically, you’ll be modifying your copy of MLR, Arcify is a library rather than a typical Norns script.

Rather than choosing it from the Norns menu you’ll:

  1. Download Arcify
  2. Copy the ’lib’ folder inside the MLR folder
  3. Add some of the code found in this file to the MLR script.

Right now, installing the library needs a little bit of familiarity with coding on Norns. I’ve been trying to figure out a super easy, copy-paste-able way to let anyone use it. Let me know if you get stuck on the above steps!

(In the long term I want to figure out integrating it into the Norns exactly the way Midi controllers work, so you don’t even need to add code to your script.)

Does that have any impact if there’s no Arc connected? I was thinking that it would be very useful to add it into @olivier’s Compass to control the loop start & end points.

It doesn’t cause any errors, it just leaves some unnecessary params in the parameter list. So yeah, feel free to proactively add it to a script! I’ve been meaning to add some pull requests to other folks’ scripts too.

It would be nice to have it test if an arc is connected, and only add params if there is one connected, just to add less cruft. I’ll put that on the list for the next release.

(Mods, this probably should get merged into the Arcify thread btw)

OK, had a shot at adding this today. It works provided I turn the Arc fast, butslow turns have no effect. I’ve instrumented the code in arcify.lua and can see the changes being applied to params at the function at line 344. However it results in the same value for each call as if something is resetting the parameter?
I also note that the code in compass makes a call to params:delta rather than params:set.

#20

OK, changing it from a params:set, to params:delta seems to work better. I’ve noticed that whatever mechanism compass uses when the commands change the loop start & end, that doesn’t get reflected in the Arc leds (though it’s possible that that actually makes sense, the start/end defines the bounds for the softcut start/end).

#21

I might have to take a look at this one, but you may be able to get the feel better through adjusting the second parameter in arcify:register() - just plugging in numbers and seeing what feels better?

I wonder if my code isn’t accommodating delta properly - I’ll take a look!

Yes, I did try that. I suspect if I set the second param=1 it might work as expected.

Edit to add, yes, that does work.

#23

One of the problems I’m facing with this library is calculating a default response for the Arc encoders that feels “musical” across a wide range of parameters. Maybe I’ll look at how the midi mapping on the Norns does it

#24

Hi! :slight_smile: I’m using arcify to map some parameters in a script using the string arcify: register (parameter name), everything works, only problem is that I can’t update the values ​​in real time on the main screen while on the parameters page they update without problems, how can I do?
here an example

#25

How are you handling your redraw function? You might want to put it in a metro callback. Something like…

  local norns_redraw_timer = metro.init()
  norns_redraw_timer.time = 1/15
  norns_redraw_timer.event = function() redraw() end
  norns_redraw_timer:start()

You could also use the params:set_action function for each of the params, and then have the Norns redraw when that param changes. Depending on your script, my approach or @Justmat’s may feel more appropriate/take less code.

There’s an example of set_action in use in the studies here

I am a beginner in scripting and thank you very much for your patience!
I’m trying to edit the UHF script by adding LFO and Arc control.
I tried the @Justmat method and it works but slows down a lot and creates latency.
I attach the folder with the script if you want to try it and help me. the samples of the script “uhfrhythm” takes them from the DRUM folder that I created.uhfrhythm.lua (8.6 KB) uhfsetar.lua (8.5 KB) README.md (36 Bytes) arcify.lua (10.8 KB) hnds_uhf.lua (2.7 KB) uhf.lua (8.7 KB)

#28

the result that i want is something like that but with the parameters that update on the screen. :grimacing:https://llllllll.co/uploads/default/original/3X/a/f/afa7d7b5d6fe6518b1054a76ad1ca5a4119dceb3.mp4

I haven’t had a chance to look at this but you might want to try just increasing the rate of @justmat’s metro example. 1 / 30 might feel a little smoother. You do reach a point where the Norns can’t keep up though.

I’m away from my studio right now so I can’t tinker with your code but maybe start there?

#30

Does this script still work when accounting for the new global params section? I would love a chance to use my arc with basically ALL my norns scripts, but I’m not getting read outs on the norns nor am I seeing it in the params when I try to drop it in on something like MLR for speed_slew rate

I’ve done a little more reading on this script and I get it now. I see where I made some mistakes with adding params. Will do some more building and testing later today.

I recently tore down my studio and put it in storage, so I haven’t been able to look at new Norns features or update any code. If anyone wants to give this a shot via pull request I’m happy to offer advice and explanation of the architecture.

The test script seems to work, and being terrible at Lua, there’s a very good chance this is on me. I will try again with a more simplistic parameter than what I previously tried and see if I can get it working right.

Trying to add arcify to molly_the_poly. Very inexperienced with coding in general, trying to break into it with something useful.
Copied molly_the_poly so I won’t break anything. Threw arcify.lua into molly_the_poly’s lib. Copied the code provided on th github into molly_the_poly. Save the script. Molly is still working, but I don’t see anything in params. Did I not “instrument” the code? I’m not sure what I’m supposed to do once it is in the script. Reading the docs provided on github, but I’m not proficient in lua enough to understand what the next step is.

Test script works. Beets works. I’ll open up beets, maybe ill see what I’m missing.

Also, I have a push button arc 2. I would like to learn how to include the push button aspect to scripts as both an individual button for on/off pause/play and as a modify for the two knobs in order for 1 knob to adjust 2 values so that the arc 2 can do everything modern arc 4 can.

Feel free to message me.

Edit: The lovely folks here Discord Norns Study Group helped me out today. I am now able to map existing script parameters to my arc 2!
