question about tract.js

        var r = this.reflection[i] * (1-lambda) + this.newReflection[i]*lambda;
        var w = r * (this.R[i-1] + this.L[i]);
        this.junctionOutputR[i] = this.R[i-1] - w;
        this.junctionOutputL[i] = this.L[i] + w;

from 2.5.2 Physical Modelling of the Vocal Tract with the 2D Digital Waveguide Mesh by Jack Mullen，
I get a different function:
w= r * (this.R[i-1] - this.L[i]);
this.junctionOutputR[i] = this.R[i-1] + w;
how I got function as follows:

junctionOutputR[i] is the combine of transparent of R[i-1](wave come from A[i-1] to A[i]) and the reflection of L[i](reflection of wave L[i] from A[i] to A[i-1] ),as follows

Brilliant... Implement Midi for musical use?

I love this app. Best voice physical model ever! I play a wind synthesizer and love modeling formants and voice sounds with synthesis.

Could I pay you to make a version of this that would allow midi to control pitch with midi note/pitch bend. And also use 4 midi CC numbers to simulate 2 x/y finger touch points through a midi instrument? And midi note for gate/mouse click so to speak. Or something like these. And midi volume.

Would be an earth breaking way to use it musically. Or if you made similar as an AU plug in for Logic Pro and other daw's. I bet maybe would buy it (and I would certainly publicize it).

Here's a vid of my music and some of my instruments/experimental approaches... https://youtu.be/wZbQVEFe_QQ Thanks! Amazing work. You are incredibly smart.

Accessing parameters such as variable positions of tongue, lips etc..

Hello,

I have a few questions regarding pink trombone. Here are they:

1. Is it area function based synthesizer?
2. I was wondering how can I see/check the parameters (variable positions of tongue, lips etc..) that is being used to generate audio/voice for pink trombone? Should I connect to backend/any server to see the data? If yes, How to connect?

Thanks,
Praneeth.

Reversed linearly interpolated values

Might be misreading but I think the reflection and newRefelction variables here are reversed.

Lines 169 to 174 in 84f9e2b

	var r = this.newReflectionLeft * (1-lambda) + this.reflectionLeft*lambda;
	this.junctionOutputL[i] = r*this.R[i-1]+(1+r)*(this.noseL[0]+this.L[i]);
	r = this.newReflectionRight * (1-lambda) + this.reflectionRight*lambda;
	this.junctionOutputR[i] = r*this.L[i]+(1+r)*(this.R[i-1]+this.noseL[0]);
	r = this.newReflectionNose * (1-lambda) + this.reflectionNose*lambda;
	this.noseJunctionOutputR[0] = r*this.noseL[0]+(1+r)*(this.L[i]+this.R[i-1]);

No option to plug nose

separate index.html into multiple files

If we want to make it easy to play around with the code and add new functionality, a good first change would be to separate the JavaScript from the html from the licence/header comments into multiple files (which would improve readability).

This would be a nice way to get acquainted with the code, so I'll look into it once my exams are done if no one else is interested in taking it on!
