How to display the values on a bus
by Alessandro Fogar

Rate this Message:
Hi,
please let ask a (probably silly) question: I am currently using JitLib and I was looking for a way to display (graphically or not) the values of a control or audio bus. I know I can use scope but that's not sufficient for me. What I have in mind (if graphically) is something like a range slider and a number showing the values on the bus or better a graphic window with the values displayed on a graph. Or it could be enough to show in the post window the immediate value but ignore how to do it, tried poll but couldn't understand how to use it.

If you look at the Bus help file you can see how to use ".get" along with SendTrig and an OSCresponderNode to assign the bus value to a variable or GUI object or whatever you want. If you want it to work with a GUI though you need to put your value update inside { }.defer or it won't show up. Something like this should get you started though.
b = Bus.audio(s); //for if you didn't already have a bus set up { SendTrig.kr(Impulse.kr(1.0),0,0.9); }.play; //this will tell our OSCresponderNode to get the bus value once per second (the Impulse) OSCresponderNode(nil,'/tr',{ arg time,responder,msg; b.get({arg val; val.postln;}); //when the trigger from SendTrig happens, it will post the value of the bus }).add; -Cole

Have a look at Andre Bartetzki's AudioMeter class which you can get here: Hope that helps, Paul On 6 Aug 2008, at 16:14, Alessandro Fogar wrote:

Hi,
for me it does not work and .get, in the help file of Bus is listed as a method only for control buses, I have an audio rate bus. I think there should be something like bus.inspect(). Is it possible to use .plot someway ?

As sort of a workaround you could wrap your bus read function inside A2K.kr which will convert it to control rate.

You want something like this:
b = Bus.audio(s); // needs to be after the point in the chain you want to measure SynthDef("readBus", { SendTrig.kr(Impulse.kr(1.0),0,In.ar(b)); }).play(addAction:\addToTail); OSCresponderNode(nil,'/tr',{ arg time,responder,msg; msg[3].postln }).add; // something to read {Out.ar(b, SinOsc.ar(mul: 0.2)) }.play S.

Scott,
many thanks... It works, but ... Can you please show me how to display the value on a simple GUI (a number box and a range slider) ?

Oops, sorry that's not a range slider, but I think you should be able to work it out with EZRanger. S. On 21 Aug 2008, at 16:37, Scott Wilson wrote:
