Frequently Asked Questions

It's not quite as pristine or refined, but the aggressive hard sync character can be very rewarding for industrial or experimental sounds.
Yes, the triangle wave is excellent for slow modulation, though the square wave's duty cycle is fixed and not adjustable.
While the 921B functions independently, linking it to the 921A expands modulation possibilities for pulse width and other parameters.
