Hi All,
I’m not planning on building this but I read all of theseconstruction/planning with interest! ;-)
I may have missed the discussion so forgive my rambling if Ihave, but in case not, there are several different diameter counting dialsavailable that could be considered in the design. While the large ones look thecoolest to me, there are counting dials that are only about the same diameteras a 10 turn pot which would work well for a more compact design while stillkeeping the turn counting functionality. In fact, I think the smallcounter is slightly smaller in diameter than a standard MOTM knob. I’veuploaded a comparison picture to photo album in this group called “Stuffby JLR” Here’s the link to the knob on Digikey’s site:

Subject: [ModularSynthPanels] Re: Living VCO
Will and I were talking about this -
We think that the two Living VCO panels worth considering are bothcounting-dial (Vernier) versions; the difference being a 5U and a 7U version.
The 5U version uses the smaller knobs for all 16 controls except the threeverniers. There are no significant modifications to Jurgen's design orsuggested hook-ups. I can't quite recall, but two of the switches may besomething Will suggested, but if so, they're very straightforward additions -of that I'm certain.
You can read about our ideas and see our panel designs here: http://www.dragonflyalley.com/constructionJHLivingVCO.htm
OK - so that's the 5U panel...
The other panel worth considering is a 7U design. If you increase the knobs tostandard MOTM size, you need 7U of space. You can implement the 7U with theverniers off-set a bit to make more space in the "driver section" forthe switches (the design on top on our page), or you can even out the grid assuggested by Greg James (the design below the others on our page).
In either of these cases, there's space for an extra row of jacks - so wefigured we'd build three wave-shapers into the module... a relativelystraightforward thing to do using 3 MFOS VCO pcbs for their wave-shapercircuits.
You could implement the 7U panel without the waveshapers and extra row ofjacks.
But if you really didn't want the verniers, you could do the Rough / Fine tuneidea a-la Dave Brown.
So to re-cap - I guess here are the choices:
1. Verniers and small knobs 5U
2. Verniers and large knobs 7U, offset verniers and including waveshapers
3. Verniers and large knobs 7U, even verniers and including waveshapers
4. Verniers and large knobs 7U, offset verniers no waveshapers
5. Verniers and large knobs 7U, even verniers no waveshapers
6. No verniers, different design
