The PPG WaveGenerator comes with a multitude of wavetables. The sound material contains the typical sounds from the original PPG wave models, as well as many new sounds generated by versatile analysis tools and also hand edited waves. This plugin enables the user, to create his own wavetables in a playful way, and to hear the result immediately. Also you can construct the waves by adding harmonics very precise.

Interesting that this started out as an iOS app.
