Most keyboards, though they have 62-128 notes of polyphony available, are forced to layer sounds in order achieve a thicker or warmer sound. Most products layer up to four times to do this, so your 64 voices are cut dramatically.

Though a program on a K2600 can have as many as 32 layers available at once, its unlikely that you are triggering more than one voice at a time. Generally Kurzweil uses these extra layers to control certain aspects of the sound...contouring the response of a piano sound across the range of the instrument, or independently processing sounds in a drum kit as examples.

In addition, Kurzweil's K2600 has the ability to generate raw waveforms which don't use any polyphony. So a typical synth program can contain 3-4 oscillators yet only use one voice of polyphony per note.
