I got a free Lexicon Vortex because two of the three encoders were on the fritz. After ignoring the warning that the encoders were unobtanium, and finding that to actually be the case, I came up with my own solution to the problem:

I haven't done a complete put-it-all-back-together test, but I expect to in the next few days. I wanted to stick my toe into the water and see if there would be any interest in the community at large for a solution to this problem without being able to buy the actual encoders.

the TLDR version is that I have a standard hex encoded switch/encoder, driving a PIC, driving transistors to emulate the original switch.

If there's enough interest, I'm interested in possibly making PCBs.... If not enough interest to be worth all that, but someone still needs help I'll be happy to share my stripboard layout and code. Testing the waters first though...

And no, I'm not going to post to Muff's until I've actually put it all back together and confirmed it, so this is sort of "pre-release" cos I know this community is not nearly so overwhelming Very Happy.

Good news, it works!

Bad news, the knobs don't fit and I broke an encoder trying to force it!
