Happy Halloween, everybody. It’s the one day out of the year when the rest of the planet enjoys spooky sounds as much as we do, well, all year long.

Solid State Logic (SSL) is celebrating with a free plug-in for Mac and Windows (VST / AU). Registration is required, but otherwise, no strings attached. They write:

In response to ghost stories of economic doom and gloom we invite you to celebrate the festival of witches and ghouls with a bit of fun. SSL is proud to offer you ‘X-Orcism’, our free Halloween VST/AU format plug-in. Feed in your voice and you will be transformed into the voice of Halloween itself… be afraid, be very afraid.

Should be fun if you’re hosting a Halloween party, and you can try it on a drum loop.

I like the Jack-o-Lanterns, though severed head of the Headless Horseman would have been even better.

Other Halloween-themed goodness? Do drop us a line. Please, no Theremins: we consider them beautiful, Classical instruments and there’s nothing scary about them at all. CDM readers with kids most likely play elegant lullabies for their offspring on the Theremin each night when they’re not lulling them to sleep with a sequenced ARP melody.
