ok, I'm having some doubts as to whether my bias knob is working properly. Going by the endangered audio clip, it seems like in the VCA mode w/ a square wave it can act somewhat like a gate, but on mine it seems to just lower volume, and eventually the modulation. I dunno if that's a result of a difference in the way they wired theirs up or a mistake I made.
Here's an example of what I'm talking about:http://www.mediafire.com/?a5t3ntmmdm2
Depth and Bias are at 100%, and the LFO is set to a square wave. From 0-9 seconds I'm adjusting the LFO frequency. Then at 9 seconds I start to turn down the bias knob - you can hear how it starts lowering the volume, and eventually killing the modulation as well.
Can anyone confirm if theirs does this too?
