Waldorf Wall Clock

via this auction

Update via Till "Qwave" Kopper in the comments: "the only legal Waldorf time is found here: link

The clock is not an official Waldorf product. I think it is made by someone uploading the logo to an online shop like spreadshirt (or the plenty others doing single item prints on cloths, mugs and even clocks)

keep on turning these knobs

Pictures of dead CEM chips

"It has long been known that the CEM chips used in so many synthesizers were semi-custom IC. Doug Curtis, just out of college, had won a design contest sponsored by Interdesign (later sold to Ferranti/GEC Plessey) and went on to work for Interdesign before founding Curtis Electromusic Specialties, later to fold into OnChip Systems. The founder of Interdesign and designer of the '555 timer chip, Hans Camenzind, still operates consultancy business in mask programmable analog semicustom IC, Array Design and has written the book Designing Analog Chips that is available free for download or as a print-on-demand hardcopy.

Here are the first two pictures of de-encapsulated (defect) CEM chips, more to follow as time permits."

Roland D-50 & Alesis Andromeda

YouTube via Hossinfeffa
"Little experiment done in a style similar to RetroSound. I made a choir patch on the D-50, and MIDI'd the D-50 to the Andromeda's analog pad sound. These two combined shocked me as it was a heavenly combination that seems like something from a JD-800."
