I'm looking for help from people much more experienced than me with wavetables and PCB design.

I'm having an issue with my Audician 32 Plus and the WavetablePi that’s been bothering me. The original WavetablePi design is too long to fit properly on cards like the Audician 32 Plus—or even the ESS Audiodrive, from what I've seen. You have to bend the setup awkwardly so that the WavetablePi doesn’t get blocked by the neighboring ISA slot. On top of that, a few capacitors are also in the way.

To solve this, I decided to try designing a riser + spacer for the sound card and the wavetable. This is my very first attempt using KiCad. I started from scrapcomputing’s KiCard files, which helped me get going. I know one of the connectors should be a 26-pin male header, but replacing it in the design was too complex for me at this stage.

Could someone take a look and let me know if the PCB is designed correctly? Did I manage to get the essential connections right?
