[sdiy] VCO CV summer

[Stewart Pye]

Hi,

I'm designing a small VCO core PCB that I can plug in to different panel 
PCB's, so I can easily build VCO's with different features or for a 
different form factor without laying out the VCO core again. I'm 
wondering is it OK to have an inch or two of PCB trace from the op amp 
summing point to the summing resistors? It would make sense to have one 
CV input pin and have the summing resistors on the panel PCB, but I just 
want to make sure this won't cause problems...

Regards,
Stewart.
