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.

Amazingly frustrating

This would be the synthesizer of my dreams, if only I could figure out how to use it. The functionality is amazing but the UI is very poorly designed, and the user manual doesn't help. For example, I created a new voice by editing one of the factory presets extensively, but when I tried to save it as a new voice, the app told me that the bank was full and I had to create a new bank. The UI doesn't explain the mental model of the bank manager, and the manual only documents the options. After wrestling with it for hours, I still have no idea how to manage banks and store custom voices. Also, there's no feedback when changing keyboard octaves or selecting between keyboard edit and play mode. If the developers had only used a good UI designer or done some usability testing, this would be the best sound design and synthesizer app in the store.

Favorite synth ever; some requests please!

If you love morphing synth sounds, this is for you. If you get ADHD when playing synths because you want them to change sounds with your mood and expression, this is for you. Desktop computer VST quality in an iOS app.

Just a couple requests for the devs please. First, an easy one: please add note transpose. Sure, you can do it thru Aum, but then you lose some of the control, like delay. Also, would it be possible to “lock the pitch” when moving the icons around? As it is now, moving icons will cause the pitch to go up or down octaves. The option to lock pitch would be nice. Further, the ability to lock other parameters while moving icons would be cool. Also, the ability to move more than one icon at a time, like in MiniMapper, would be sweet if possible.

Thanks PPG team! Great job on this and all your apps!

Great synth! One of my top favorites!

The UI can feel a bit alien at first, but after some use, it becomes easier. It’s actually very touch oriented, meaning controls are all big enough to respond to your intentions as opposed to something like that center window of Cyclop app, where adjusting tiny parameters is a hit or miss. WaveMapper is precise in that sense and is one of my fav synths of all time because the sound quality and range it offers is just top notch.

You can convert all kinds of audio samples to internal wave table format in it and result is closer to original that I’ve heard so far compared to some other apps I’ve tried. Which is really cool for experimenting.
