From the README:
This is a collection of "boring" (empty) WaveTabulator sunsynths for SunVox.
They act as mixers between a matrix of sound generators that you provide yourself.
The simplest is WT1-2, which is one dimension, two sound generators.
When you fade the value from 0 to 16384, it mixes from the first to the second generator.
When you fade the value from 16384 to 32768, it mixes back to the first.
The one-dimension templates go up to 16 slots.
The last slot always wraps around to the first.
This is to allow you to drive the dimensional selectors using a sawtooth LFO
to get seamless morphing between all sounds.
Some multi-dimensional configurations are available:
2x2 (4 slots), 3x3x3 (27 slots), and 3x4x5 (60 slots).
You'll need to dig into more layers of MetaModules to fill in all the sound generators.
