Remaking the keys synth from the 1980 song "Mr Crowley" by Ozzy Osbourne can be an exciting challenge for any synthesizer enthusiast. Here’s how you can create the "Mr Crowley" keys patch and play this iconic sound on most hardware or software subtractive synthesizers (Serum, Vital, Pigments, Prophet, Korg, Moog, etc). We've included the preset download directly for your convenience, but we strongly recommend you use our programming tutorial to recreate it yourself.
Original Audio
The opening of Ozzy Osbourne’s “Mr Crowley” features a massive organ-like synthesizer sound, created by Don Airey using a Yamaha CS-80. This rich, resonant timbre dominates the track’s introduction, heard immediately from the start. The CS-80’s polyphonic capabilities shaped the distinctive string/organ hybrid sound that defines the song’s beginning.
