It's really marketing for a somewhat flexible mostly subtractive, more west coast than east coast, synth architecture with a few tricks, e.g., some ability to do FM. The original K2K has a selection of blocks that you can select to process samples. In the simplest form you can use up to four blocks which are simple filters, wavefolders, etc. Some of the blocks were more complex than others and had more parameters, and some took more than one "block space." Some of the blocks added a waveform, e.g., a sine wave. You could create several (three IIRC) layers for most sounds. There were originally 31 "algorithms" for combining the four blocks in various sizes and series parallel arrangements. For example, one block might feed the sample into two blocks of size one which were then mixed into a block of size two. You had a fixed set of choices for each of the blocks and a lot of the sound planning involved figuring out which of the major features that you wanted to use and how that drove your algorithm choice. If you wanted to use the big four pole filter with resonance, for example, you had few choices.
Later variants allowed you to run up to three of these layer sets in parallel, and the most recent variant apparently allows even more flexibility.
There is a LOT of modulation flexibility though, including the ability to apply functions to existing modulation sources. It really is still quite powerful, but not really worth bothering with today for most.
