Wolfgang Palm, the “father of wavetable synthesizers,” has released his latest virtual synth, PPG “Infinite” for Apple iOS devices. To address limitations of past wavetable designs, the frequencies of the overtones created by Infinite can be totally freely defined. Now available.

So the sounds it produces are totally free in the frequencies of their overtones. This means that each partial wave can have an arbitrary frequency. Moreover it is possible to move these overtones independently during the duration of a note.

According to Palm the main limitation of past designs is that all sounds are harmonic. In nature this does not happen very often. Many sounds like a piano string have small offsets from the harmonic frequencies. This is even stronger in sounds like bells or percussion.

“This has always been my dream. A system which can reproduce all kinds of sounds and transform them into a universal set of parameters. Thus all these sounds are completely morphable,” said Palm.

Another important part of most natural sounds is noise. Be it a flute or when a drumstick hits the drumhead – and this all can be reproduced in Infinite. Furthermore the noise source can be used to modulate the tonal part which results in very powerful effects.

Says Palm, “Besides these new digital features, we still have the typical 24db Lowpass filter, 2 VCA with stereo out and effects. All this is controlled by 10 envelopes, 4 LFOs and a modulation matrix.”

Maybe the greatest innovation in Infinite is the Morpher. It is so easy to create new timbres and real-time effects by morphing the gains and frequencies of sounds with the X/Y controller. To get an impression of the morphing possibilities watch this short video.

Infinite comes with more that 300 tonal resources, which can be loaded into the 5 fields inside the Morhper. But it does not stop there. You can edit these in detail on two extra pages and can import your own sounds from the PPG WaveGenerator and WaveMapper apps.

On the SineEdit 1 panel, you edit the sine tracks with a set of parameters for each track. A track is the time sequence of one sine component over the full length of the sound. A 3D display gives a good impression of the whole resource.

On the SineEdit 2 panel, you edit the fine structure of a track in a bargraph. A FREQ mode lets you do this for the frequency. (Pictured below.)

Key Features of PPG Infinite for iOS:

• New system which can synthesize harmonic and inharmonic sounds
• Morpher – X/Y controller which morphes 5 user selectable sine resources
• Noiser – X/Y controller morphing 3 noise resources and performing modulations on the tonal part
• Molder – acts as a digital filter with any amaginable filter sweeps
• Two detail editor pages for the Sine resources featuring a 3D display
• Import WTS and TCS files from the iPad WaveGenerator and WaveMapper
• Import Phonem utterances and use them in the Infinite Molder
• Versatile matrix system – allowing 16 sources to control 40 parameters
• 10 Envelopes, for control of filter sweeps, waveform, noise and many modulations
• 4 LFOs which can be freely routed via the matrix
