A while back, like an idiot, I stripboarded six Cat Girl Synth bandpass filters, and wired them to a stripboarded DC mixer. The resulting nightmare mess is pictured above. It’s like I don’t believe in front panels.

At the time I’d lost my 15v power supply so I couldn’t give a test on the full wotsit. Well, I’ve found it now, so here’s the Roland SH-5, scratchy pots and all. Scuse the hiss.

And here’s the CGS30 BPF, running at 15v.

Near enough, really.
