Blend is a switch you turn on? I thought wet/dry blend was always in the circuit?

Also, I was hoping there was gonna be a limit feature added....20:1 for example. Like the Smart C2.
 
Cool stuff! Awesome work.

What options should one go for if getting it fabbed at JLC?
1.6mm and HASL w/lead unproblematic? What benefit added from say 2mm and ENIG, thicker gold etc...

What to do with vias?

Check box for "2 designs", so panel/switch PCB will be separated from main board?

I acknowledge that this is on the fringe of the scope of this thread, but thought and recommendations are appreciated.

Oh, and where would I tap the side chain to a switch, so I can use external key input for ducking uses?
 
1.6mm with HASL should be fine for this design.

ENIG is an unnecessary extra cost in this case IMO. Lead is only problematic if you live somewhere that has rules about it or are already using lead-free solder, or if you plan to eat it (I mean, lead is obviously problematic in a general sense, but I think you can understand what I mean). Gold plating is useful on something like an edge connector that would need to be wear-resistant, but not needed for this board. From what I can see, the most basic default option from JLC should be just fine.
 
Sorry for troubling....
just for learning purpose and fun tried to simulate the CT net of the original Gssl compared to SoundSkulptor version in 500 format, since the last one has a smart configuration with only 2 caps..... believe to save space and the number of caps.

except the autoRelease position,where the slopes are very different maybe due to the dual element REL with different values, otherwise the curves are very close/similar...

What is your opinion?

thanx for your attention

On your diagrams you have one drawing where you have the 2 caps (6u8 & 0.47u) in different places.
 
are you meaning a different configuration and so different behavior?
what i get in mind is that when not in auto mode the 2 caps can be considered in series and so a value like 440nF....
in auto mode R12 & R13 are no more shorted to GND and so you can get a dual element Release....
also i did an error drawing it, i removed a connection at R6

edit: Altering R11 form 100k to over 1meg, the slopes are almost matched
