Oberheim OB-8 Oscillator Synchronization

This is a sound programmed on the Oberheim OB-8 using the oscillator sync mode. I set each oscillator to the pulse wave, enabled sync, then modulated the frequency of the synched oscillator. This made a very rich sound and when I viewed it on the oscilloscope I saw these crazy animated castle walls going by. I used my Nexus One to shoot the screen then added in the recorded audio so you can properly hear how it sounded.
