Charmed Snark and the synth crosspoint issue

[cardiffborn]

Hi
I was having a look around for crosspoint designs, to use with some analogue synth equipment, and came across this thread:

and was wondering whether the problem ever got resolved.

I do have a Sealectro 60x60 matrix but was looking to try something more compact and without so much wiring.

Any help welcomed
