Hi Paul,

Thank you. I played around with it some more and this is what I discovered...

As I move the Pulse Width Slider towards "0" the saw or pulse wave starts to narrow (as it should) but then another saw or pulse starts to mix in and cycles between the pulse/saw wave and this new wave. So, at the center I only hear the pulse or saw wave but as I move the slider towards "0" or "100" it starts to alternate on/off with this new wave. At "0" you are left with just this other wave. It sounds like this other wave is an octave lower.

What's weirder is the frequency of the oscillation between the two is controlled by the Sweep Rate slider and type (sine/square). This is with the scratch patch and is not affected by Sweep Depth. Again this is only occurs on Oscillator 1.

It also seems to be intermittent as this morning it worked again but this evening it came back.

Does that make sense? Does it still sound like a faulty slider?

Thanks.
