Korg Micro Preset M-500 SN 770606

via this eBay listing
"Korg M-500 Micro Preset circa 1978, famously used by Orchestral Maneuvers In The Dark, Portishead, etc. The controls are a bit limited, but it has a huge variety of sounds, does everything from thick basslines to horns, strings, woodwind, and a theremin-type setting. You can combine any 2 sounds together for some really cool tones.
One issue that is common with this model, is that Korg used a certain type of capacitor that over years, eventually leaks, causing failure of the synth and damage to the traces on the circuit board. Many of these M-500s you see for sale are not working or only partially working, due to the failed caps. When I got this synth, I replaced all the electrolytic capacitors with modern panasonic caps and cleaned the whole circuit board, so it's working perfectly and will do for years to come. Everything works exactly as it should with no issues and it sounds amazing! A very cool and unique monosynth capable of some really great sounds."

Cross-spectral transfering
video upload by Frap Tools
"FUMANA has a special array of 16 bandpass filters exclusively built for spectral analysis. It can thus transfer the energy of the modulator signal to the exact portion of the carrier’s spectrum.
However, many traditional filter banks used just half of their bands to transfer the energy over the other half, like the odd over the even ones, or vice versa.
If you want to replicate this behavior with FUMANA, fear not: you just need a handful of patch cables, like in this video!"

Bastl Kastle 2 FX WIZARD #6 / "Wizard goes into oscillation!"
video upload by alloutofsync
"The FX Wizard goes into oscillation. I’m using the ARP just for converting patch cables to stereo and for grounding. It’s not powered. In post, I added a touch of reverb and delay.
