Ok... so it's not really the Bride Of Frankensynth it's PINKY a synth made mostly from CGS modules built into a mannequinn... I was looking around for Halloween inspired music synth stuff and it was either this or the Soundcraft Ghost :)
To carry on with the Halloween theme... you can find a lot of craptastic spoooooky samples HERE. There's the typcial creaky door, evil laugh, moans, groans and female screeeeaaaams!!!
If you're not into Halloween cheese you can find much better horror and scary/eerie themed free samples over at the Freesound Project. Thunderstorms, ambiences, soundscapes with name like tension and taut. Very good stuff.
Ok one last Halloween theme and that's it for this year. Screaming Lord Sutch singing Jack the Ripper recorded by Joe Meek one of the first sound engineers to use the studio as a musical instrument.
