Hello, I'm in the process of trying to grok javascript with Jitter (haven't gotten very far yet), and had unexpected results with this patch, which is attempting to make a simple xfader. The below function is called with numbers between 0 and 1. When just above or below the extremes, it functions as expected. However, when set to either 0 or 1, the output goes to 0 (black). Any ideas why? Thanks!

    tmpMat1.op("*", scalarMat1, myMatrix1);

    tmpMat2.op("*", scalarMat2, myMatrix2);

    outMat.op("+", tmpMat1, tmpMat2);

    outlet(0, "jit_matrix", outMat.name);

[msg changed] still puzzling through, and particularly curious why one side of the switch (non-integral values) works and the other goes to 0...
