Patch: Submerged

The SY-300 has the option to generated narrow band noise by raising the sharpness parameter of a noise oscillator up to high values. You can, in fact, raise sharpness (and thus limit the bandwidth) of the noise so far, that it doesn’t sound like noise any more. It’s sounds more like a gaussian modulated sinusoidal pulse. And you know which acoustic based system uses similar pulses? Sonar! So PING away (best played on the high e string):
