Frequently Asked Questions
It smooths out rapid pitch changes, preventing harsh jumps and allowing for more controlled, expressive sweeps – think slow, evolving drones.
Absolutely, it’s designed for driving BBDs and other modules needing fast signal transitions, but be mindful of potential aliasing at extreme frequencies.
The A-188-9 has a more 'analog' feel—slightly less pristine and more characterful than some newer digital oscillators, lending itself well to gritty textures.
