Hi Guys - On our site, we show a 4U version with some tiny (1/2") knobs. We're almost certain everything will fit behind the panel but we're going to do a very careful experiment to make sure. Before Scott makes any panels, we'll buy some of the 1/2" knobs and lay them out and photo it all so everyone can see exactly what it will look like, OK?

At Scott's suggestion, Will developed an alternative 5U version. It's exactly the same layout, except it has a slightly larger (and less expensive) vernier (counting) dial and it uses the "Tellun" Standard .67in dia knobs that match MOTM standard except are smaller.

In both these layouts, Will kept as many as possible of the control elements on the standard MOTM grid - especially the horizontal - and they both look real good (to my eye).

In our case, if either the four or five U version is made, we intend to build a 1U sister module with three wave-shapers to supply SIN, SAW, TRI, and SQR outputs for each VCO.

We've already done the research on this - it looks like it can be accomplished by using three MFOS VCO PCBs and feeding the "core" output of each Living VCO into the Wave-Shaper section of the MFOS circuit at R12. (please review)

So at my request, Will also developed yet another panel layout that includes the wave-shaper outputs in the same panel as the Living VCO. It's 7U, (one unit larger than the 5U plus the 1U daughter-board), uses all MOTM standard knobs (except the larger counting dials), and has the SIN, SAW, TRI, SQR outs at the bottom (a-la the MOTM-300) as well as the standard Living VCO outputs.

At the moment, I haven't got time to give the 5U and 7U versions a final review and post them, but I promise I will when I have time later on tonight.

As for me, I'm leaning toward Will's 7U version. I know it sounds crazy - and most people will want the 4U or 5U versions. So I'll probably ask Scott to do a one-off for us (although I have heard interest in the 7U from at least one other builder).

Still the 4U or 5U is going to suit most people just fine.

Again, I'll post them later one way or another.

Thx.

Bill (and Will)
