At the end of the 70s wavetable synthesis. This was very successful and used by many synthesizer companies in the 80s and 90s. But this technology has its limitations. The main reason 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.
Infinite PRO overcomes this limitation.
The frequencies of the overtones created by Infinite PRO can be totally freely defined. 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.
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 PRO. Furthermore the noise source can be used to modulate the tonal part which results in very powerful effects.
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 PRO 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.
