I also use the “preview offset” knob on my console.

Surely you can do the same thing by adjusting the output level of your preview signal if you’re going from your DAC to the pitch control?

The burned black viinyl compound is stuck to the inside of the barrel and on the screw of the extruder and some of it is coming out. You will see it better with white vinyl. These burned pieces will give you noisy records. The vinyl cake should ideally be about 10 degrees C lower than the mould temp...

Is that clear vinyl compound?
