White Horse, IC1D pin assignment reversed?

Hello,

On the schematic IC1D, pin 12 should be the (-) input and pin 13 (+) this is reversed. It looks like from the tracing that the input does go to 12 (-) inverting, but then there is positive feedback to produce gain? I'm at a bit of a loss here.

Thanks

For quad op-amps like the TLE2074, TL074, etc:
Pin 12 non-inverted input
Pin 13 inverted input
Pin 14 output

The schem and traces are in agreement with this.

Yeah, the right side of that diagram is wrong. The inverted input and output pins are always adjacent.

You are correct - the WhiteHorse inverts phase at its output. It's set up this way because of the way the Blend control is designed to mix the clean and compressed signals.
