[sdiy] digitally switching cv and audio lines

[Guy Taylor]

Hi there,
I to would love to see the eagle project :)

Has anyone looked at the AD8113? It's a bit bigger and more expensive than
the AD75019 but may be better as it has much lower cross talk.
I'm a novice to DIY but surely, cross talk would be a major concern...

Cheers
Guy
