So who's still out there building frac? Show me some pictures!
I've had some time on my hands and nowhere to go, here's what I've finished lately...

Your stuff always looks so good :hail:

What is the double envelope? The panel is very Blacet looking!

I haven't got any pictures as nothing is completed, but have a SSI2144 filter that is waiting for a panel, and just hooked up a VCO yesterday so need to do a panel for that. And I'm building someone on here a CB-55 drum module in Frac, again waiting for a panel to arrive from Germany. But mine are in mini-jacks 8-)

Ooh! I like the look and layout of that Sequential Switch! Clever to tie it together and have it look interesting, while keeping knobs, switches and LEDs accessible!
What circuit is behind the panel?

Thanks! The dual envelope is a mfos dual ar. It is very much a riff on the blacet style. The sequential switch is from cgs.

I have a couple old Frac modules on the wiring table.
Currently working on an Ian Fritz TGTSH,
and a combo panel with a CGS Psycho 6 LFO feeding an Ian Fritz Double-Well Chaos.

After finally acquiring a Kilpatrick Phenol and finding some better quality banana cables,
I have to say y'all were right.
3.5mm jacks suffer from the cable crackle
which can really disturb your patching flow
and disrupt large patches in a way that is frustrating to troubleshoot.
3.5mm cables are harder to make and break more over time than good bananas.
Banana connections are more reliable.

I kinda regret having invested so heavily in 3.5mm jack stuff.
I suppose some designs aren't as easily available with bananas (LZX for example),
but envy all your lovely banana systems.

Another format choice I wonder why we don't see more of is simple rack panels.
1u rack would be the smallest module unit.
This thinking seems to make a lot of sense for combo-modules.
