Yes, there was only one wire that was suspect, and I just double
checked the wiring via the midijack installation page.

The only other things I had done, were reseat the connectors on the
board with the VCA and VCF on it, and the connectors on the board
with the volume pot. I just checked them again, everything is seated
fine.

It is only making sound on the release of the key, not the initial
press. And the VCA controls seem wrong, they're working but in a
strange way it seems. I'm very confused by this.
