I've updated the drawing - which I'll post later - that includes the audio signal path, metering and sidechain on two sheets.
For the moment I'll be pulling out all of the component designators in the drawing and reassigning them from the layout.
It's a little tedious that way but it makes manual DIY assembly easier when the "R" and "C" numbers ascend in some from of order that follows the PC board.
Once I finish that process I'll post it.

With all the various blocks on two pages and with the full picture I can start a layout using existing portions of the Waveulator board.
Nine of the IC stages and the process relay are identical.

The challenge is making it all fit.
The Waveulator has 20 ICs; the Uno Compressor has 21.
The Uno Compressor's "extra" IC is a 14 pin THAT300 so it may be a little tight.

Seeing its been a while, see you offer quadrature summing boards cool!
How are things going with the Uno comp?

Thanks for the post! The Lawo's filter, when drawn, has a nice visual symmetry.
I've occasionally seen them for sale on eBay.

The Quadrature Summing Filter board has done better than I thought it would.
The last order was for vinyl lathe with a mono cutter head.

Once I get caught up assembling PC boards I hope to return back to the Uno Comp project.
I'm so close to doing a layout for it.
