Subject: [Evolver] VCA amount bug

Did anyone else experienced the following bug?

When the VCA env amount = 0 and VCA level = 0, the VCA still gets triggered by the VCA env.

And when this happens you hear the digital fuzz problem that many of you already described on this list.

You could try it yourself. Just dial up patch 128 in Bank 2, it's a very simple patch. It's got the VCA env amount = 0 and the VCA level = 0 values by default.

I noticed that when I raised the VCA env amount to 100, the digital fuzz problem dissapeared almost completly.
