Eric - All -

We took a look at the Randomsource Living VCO PCB - it has some clever features that our panel doesn't reflect (having only glanced at Randomsource at first, we didn't see the VCA/distortion/overdrive feature).  Let us review it and see - I think a modest modification to our design will easily accommodate the full feature-set.  Gotta say - Randomsource sure has done a nice job.  The Eurorack add-on is a clever addition, but, of course, it does we 5U-ers no good.  How was the build?  Easy enough?

Bill and Will

Eric - 

Will and I designed just such a panel back in 2010 or therabouts. As soon as Jurgen emailed us about the VCO (in the way-back time) Will asked him what would be involved with adding waveshapers in the form of a daughterboard. He had some correspondence with MFOS about the idea of using the VCO module for its waveshapers. Here is that old page for reference:

We were, of course, very sad when JH left us all. My subsequent illness (a blood staff infection that nearly proved fatal) postponed our further exploration of and implementation of the module.

But then, as I was still recovering, a couple years ago, at Gino Wong's request, we did a review and even more careful analysis of Jurgen's Living VCO circuitry design including the modifications and improvements by the community at large. And we ended up helping with his issue of a modified version of Jurgen's PCB. The results of that process is documented here:

You can see as part of that effort, we outline the additional features to be provided in the daughterboard  envisioned by Will back in 2010. These are the features which later, subsequently appeared as part of the Randomsource PCB.

So - there is a fpd file on this page here:

We have not ordered the panel so we can't vouch for its perfection. If you'd like to use the panel for the Randomsource version of the module, we (or you) can easily modify the name of the module at the bottom, of course. But if you wouldn't mind, Will and I would rather appriciate it if you leave the little dragonfly moniker intact.

If you want us to modify the fpd design for you, we'll do it happily.

It's so cool to have people posting stuff here. I've missed it.

I’m still here! I’m still here!

Just finished constructing (and am now troubleshooting) the JH Living VCO’s (the RandomSource version). Need to design an MOTM front panel that includes all the RandomSource addons. Is there a MOTM grid/template for Front Panel Express floating around somewhere?

Meanwhile, did anyone ever make a Moog-style sequencer for MOTM format? I mean, there’s the Klee, but I want a boring ol’ Moog style one without having to modify a MU-format one…
