encoder/lcd

vivian rotary encoders

that'll be an interesting task to do in Supercollider without a custom UGen. @RafaeleAndrade @jonathan @nescivi did any of you try this? Alternatively, using a potentiometer - if possible - would be much easier.

vivian im also trying to display the gui knob values and oscillator frequency's on a 40x4 lcd via i2c

One could set up a little program that receives OSC and displays content on the LCD. We've done something similar for an OLED display https://forum.bela.io/d/314-is-anyone-successfully-using-i2c-oled-lcd/72 . I believe there is some library around for a 4x20 LCD which could be wrapped with an OSC receiver in a similar way.

vivian change something like a popdown menu or gui knob to a digital in so i could use rotary encoders

the process of translating a Sc GUI to something controllable in other means is obscure to me, but I guess if the GUI is controlled by the language, you'll have to send some message from the server back to the language using SendReply.

Trill Bar would be fine!

these are the UGens for Trill: https://github.com/jreus/Trill_SC
If you are a bit familiar with the terminal, you should be able to follow the installation instructions in the README. Let me know if you have troubles with that.

It comes with examples that should help you understand how it works.

no worries, try this:

• download these three files to your computer:
  • https://github.com/jreus/Trill_SC/raw/master/ext/Trill/TrillCentroids.so
  • https://github.com/jreus/Trill_SC/raw/master/ext/Trill/TrillRaw.so
  • https://raw.githubusercontent.com/jreus/Trill_SC/master/ext/Trill/TrillUGens.sc (ensure this one is saved as .sc and not .sc.txt)
• open the Bela IDE, add the three files to the currently open project by drag and drop. You may one or more warnings about "couldn't open binary files". Ignore them. You should now see the three files among the files in your project. Verify that the extension of the last one is indeed .sc or rename it with the rename button next to it.
• run the following in the console at the bottom of the IDE (one line at a time, and replacing PROJECTNAME with the name of the currently open project):

  mkdir -p /usr/share/SuperCollider/Extensions/TrillUGens
  mv projects/PROJECTNAME/Trill* /usr/share/SuperCollider/Extensions/TrillUGens

• give it a few seconds and those files should have now disappeared from your project
• test it by running one of the example projects starting with SC_ from here https://github.com/jreus/Trill_SC/tree/master/BelaProjects

Ok let me have a look

giuliomoro Ok let me have a look

I fixed it now. Can you udpate your Bela core code following the procedure here https://learn.bela.io/using-bela/bela-techniques/updating-bela/ ?

vivian do i define the digital inputs in a seperate synth def to the existing synth engine def im working on?

Either should work.

vivian is there an existing example of digital in with send reply i could study?

not yet. I think it should be something like this to send on positive transitions (DigitalIn value going from 0 to 1):

	~ctrl = {
		var a = DigitalIn.kr(0);
		SendReply.kr(a, '/ctrl', [a]);
	}.play;

and maybe the following to trigger for both 0 -> 1 and 1 -> 0?

	~ctrl = {
		var a = DigitalIn.kr(0);
		SendReply.kr(a, '/ctrl', [a]);
		SendReply.kr((1 - a) , '/ctrl', [a]);
	}.play;

there are surely more classy way of doing it (e.g.: with a one-sample delay that could implement a one-zero filter?), but I don't know supercollider!

vivian also assigning trill bars to synth defs is the same in that we define them in a similar way to digital in?

some examples of that is in here, or do you mean something else?

it looks like you need to install the TrillUGens.sc file on your host so that your sclang knows about it: https://github.com/jreus/Trill_SC/blob/master/ext/Trill/TrillUGens.sc
