Patches and discussion for Ensoniq VFX family

Hi everyone.

Long time lurker here. I had a vanilla VFX, and loved programming it so much, that I sold it for a better-condition VFX-SD. To my surprise and delight, I have absolutely fallen in love with the sequencer.

Anyways, I am not handy at all. I don't even know how to solder, but I can unscrew cases and plug things in. I was wondering if a solder-challenged dunderhead like me would be able to install the SQX-70 sequencer expander thing in the VFX-SD. How difficult is it really?

Thanks,
-Franz
