The lower Position knob will crossfade between those 3. For instance, a wavetable with 30 frames can be split into 3 x 10 frames by setting Tables to 3. Wavetables can be split into multiple parts (up to 16), effectively creating a 2-dimensional oscillator. This panel also offers a Reverse option to flip the wavetable back to front, Cyclic mode for seamless wavetable cycling, and various real-time interpolation methods. You can manually select wavetables, modulate the wave position via the matrix, or even scan through them automatically using the envelope and loop options (which let you animate wavetables without the need for an extra modulation source).
Hive 2 includes Wavetables! These appear as multiple waveforms, and are controlled in the central hexagon.
