>Juergen's Scanning Interpolator

If someone is going to make a layout for this, please make it for
slider pots. 8 vertical slider pots, the LEDs below these,
and the manual / CV input stuff below that.
I would be interested in on of these pcbs as well. (Did I say
I don't like standards ?? (:->) )

BTW, I have a layout for the original one. It has at least one error,
though: One of the reference voltage sources was just an opamp.
But it has to provide more current, so I had to cut a few copper
traces and wire an emitter follower inside the opamp's feedback loop.
There may be other changes, too.

Yes, I think it would be the best if someone would make a PCB with
sliders for this module !

>Juergen's Morphing Programmer

Don't build this as it is. It has a stupid design flaw in the VCAs,
as Jörgen pointed out some time ago. It works, but it is
not optimal.

> Juergen's Frequency Shifter

I needed 4 boards for this one, each 10 x 16 cm**2.
I suggest a 19" 2 U rack mount box.

Joachim's dual mode ARP filter
tomg's sequencer (yes, board layout looks simple, but I want to
                  build at least five of them)
