What's a Spherical Wavetable?
A waveform
Sphere is so-named because you move between the waveforms in three dimensions (Latitude, Longitude, and
Depth), and each dimension wraps around to the beginning when you reach the end. (The analogy to a sphere is
not perfect, see the Mathematical Note page 11 if you're curious about the true geometry of the SWN.)
A Spherical wavetable (or "Sphere" for short) is a group of waveforms. Think of a
waveform as a timbre, or how an instrument "sounds". A Sphere is a collection of 27
waveforms. As you turn any of the navigation knobs on the SWN (Latitude, Longitude,
Depth, or Browse) you select which of the 27 waveforms to play. The SWN smoothly
morphs between waveforms as you navigate, thus creating new waveforms on the fly. A
