PPG Infinite – new synth from Wolfgang Palm

Wolfgang Palm has released its new iOS synth: PPG Infinite! Get it on the App Store.

At the end of the 70s Wolfgang Palm developed 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 overcomes this limitation. The frequencies of the overtones created by Infinite 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.

After the huge success of the PPG Phonem VST/AU plugin, we optimized the sound-engine to make it run pretty well on the iPad.

It has also been adapted to make best use of multi-touch and comes with IAA and AU-extension.

PPG Phonem lets the user create expressive vocal synthesis beyond anything ever heard before. With its advanced routing system every aspect of the voice can be controlled and modulated in any conceivable way. Anything from a quiet whisper to a scream. Use the intuitive text to speech tool to make Phonem say whatever you want.

Although the PPG Phonem was originally designed to do just vocal synthesis, it turned out that the system was also capable of producing a wide range of universal synthsizer sounds. So we extended the parameter ranges and made everything accessible to the user, to take advantage of this fact.

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.

Another way is to transform a picture into a wavetable. You can load photos from your album or even shoot a picture with the camera.

The waves are collected in a grid of 256 fields, to which the 3 oscillators of the synthesizer have arbitrary and independent access.

In a 3D display you get a visual impression on how the sound evolves. You can turn around the 3D object and zoom in and out,

The Parameters of the synthesizer are divided into modules, which allows easy, yet powerful editing.

It contains 3 oscillators with independent control of pitch and waveform. Each oscillator has its own glide, which gives a very dynamic sound.

With a sophisticated routing system, the diverse modulation sources can be connected to all important control points.

The keyboard is configurable totally freely, so you can setup all well-known musical scales, but also all imaginable custom scales that best fit into your music.

PPG WaveGenerator benefits all advantages of the iPad, like X/Y control after the key on event, or two finder gestures for spectrum control. After a key is hit, the tone may be modified and modulated in various ways, just by moving your finger.

A comfortable browser lets you sort the sound programs; you can categorize and rate them. Also complete custom sound banks may be created.

All significant parameters are controllable via MIDI.

There is a built in context specific help for all pages and modules.

Key Features:

• Creation of your own waves and wavetables.
• Playful sound creation simply by drawing or picking harmonics
• 3D page, visualization of the wavetables, transformation from photos into wavetables.

• Versatile Arpeggiator
• Delay/Reverb effect
• Audio engine with 2 synthesis modes, and variable wave blending quality.
• Directly accessible context help inside the app
• Use a camera, to shoot a picture and then transform it into a sound!
• Using state of the art technologies, but still the versatile and efficient synthesis system.
• Build your own keyboard, with the keys you prefer for your music.
▪ Audio Unit Extension (AU) with 2 pages.
▪ Inter-app audio (IAA) support - audio and MIDI.
▪ Audiobus 2 support.
▪ Export audio to AudioShare.

PPG WaveMapper is the second next-generation iOS based synth from Wolfgang Palm, who in 2012 released the PPG WaveGenerator to critical acclaim from both press and public.

In final development the PPG WaveMapper offers iPad users a second synthesiser to compliment the already loved PPG WaveGenerator from Wolfgang Palm. PPG WaveMapper allows the user the opportunity to create limitless sounds from this unique and powerful new technology.

PPG WaveMapper features the Sound Map, which maps the various sounds in a way to easily access and experiment with them, more importantly the PPG WaveMapper features a new synthesis system which maps the waveforms of a sound into a new kind of wavetable which preserves the sound characteristics better than classic Wavetable synthesis and at the same time allows for the manipulations which make WT synthesis so unique.

The Mapping window is the visualisation of a pool of programs on which “modules” float. Those modules represent certain parameters of the synthesiser engine and each module can be placed on one of 32 programs. The moment an item is placed on map then the parameters of that module will take on the settings of those parameters in the underlying program on the Mapping window.

People who do not posses synth-programming skills can use this mapping technology as a starting point to create complex sounds. For example a user can drag a string sound source onto a drum envelope, or a guitar sound onto a string envelope – the concept is simple, yet incredibly powerful.
Power users can delve deep into the back end of any sound using a full set of professional features;

▪ New Sound map concept – create new sounds playful and experimental
▪ 3 types of synthesis – the optimal type for kind of each sounds
    Classic wavetables – for the typical PPG sounds
    Time compressed samples – more authentic sounds, allowing analysis of user samples
    Pure samples – classic sample playback
▪ Analyzer – convert your own samples into the new format or into wavetables
▪ 3 oscillators capable for totally independent sound sources
▪ 90 sound resources – a huge sound palette, from real instruments to abstract wavetables
▪ 4 parameter editor pages – comfortable and detailed access to all the parameters
▪ 3 Noise generators, for audio and modulations
▪ Ringmodulator
▪ Classic 24 dB Lowpass Filter, combined with an overdrive simulation.
▪ Dual amplifier, for versatile control of 2 audio signals as well as panning.
▪ 13 Envelopes, for independent control of pitch, waveform, filter, noise, gain and panning.
▪ 4 LFOs – with 5 waveforms
▪ Delay/Reverb effect
▪ Versatile Arpeggiator
▪ Schematic touch keyboard – Build your own keyboard, with the keys
    you prefer for your music.
▪ Powerful sound browser – sorting by category, bank management.
▪ Virtual and Hard-MIDI in/out – sending/receiving keys and controllers.
▪ Audio Unit Extension (AU) with 3 pages.
▪ Inter-app audio (IAA) support - audio and MIDI.
▪ Audiobus 2 support.
▪ Import audio from AudioShare.
▪ Export audio to AudioShare.
▪ 30 min audio recording and Audio copy.
