iTunes Description:

PPG WaveGenerator is the latest development from the inventor of wavetable synthesis, Wolfgang Palm. It is a next generation synthesizer, building on the heritage of the PPG Wave keyboards.

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 app 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.
