Thanks for the speedy and helpful reply Alberto.
I tested this example splitting the signal in two (which still resulted in
audio in both channels regardless of Unity panners), but adding the
left/right parameterization on those outputs allows me to separately adjust
channel levels in Unity.
As for replacing sliders with just numerical inputs, I built the example
pasted below, but Unity throws an error within the associated
FaustUtilities_ script, seemingly looking for UI elements:
if (!FaustUI.fJSONParser(ref fJSON, out fUI)) { // Parses the JSON file
UnityEngine.Debug.LogError("Error JSON Parser");
}
Does violinModel by default require UI elements, even if sliders and the
like aren't specified in the FAUST declaration? Or is the manner I declared
it below confusing things...
Again, any suggestions or guidances are extremely helpful.
-------------
TEST SCRIPT (ATTEMPTING TO REMOVE UI ELEMENTS):
import("stdfaust.lib");
my_violin= pm.violinModel(stringLength,bowPress,bowVel,bowPos)*outGain
with{
stringLength = 0;
bowVel = 0;
bowPress = 0;
bowPos = 0;
outGain = 0;
};
left = 0;
right = 0;
process = my_violin <: _ * left ,_ * right;
