Let me begin by paraphrasing the late, great, Douglas Adams: the Spherical Wavetable Navigator (henceforth SWN) is deep, really deep...

It seems the words most commonly heard in 4MS R&D meetings could be ‘...and it could do this as well’. The SWN is a fairly big 26HP six‑voice module capable of creating slowly morphing drones, polyphonic melodies, evolving sequences and a vast range of rich textures. I’ll add that it also looks rather lovely — shiny black fascia with illuminated (purple!) knobs to invite tweaking, and more sockets (26) than you could shake a patch cord at! Each of the six independent oscillators have their own wavetable generator, with their own pitch, amplitude and waveform controls. Six on‑board LFOs, which can also be simple Envelopes, can be used to further add dynamic motion to patches. Those panel sockets for external CV control offer wide access to functions — even some shifted functions only accessible by the push‑and‑turn of panel knobs. As I said, deep...

The Spherical part of the title comes from the way the various wavetables are mapped, and how you can navigate through them. On early wavetable synths (eg. PPG’s), the table was simply a list — you could choose start and end points, maybe direction of scan and maybe looping of sections/all of the list. On the SWN, 27 waveforms are mapped on to a sphere in 3 x 3 x 3 planes, all of which wrap around, and...
