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.

• Creation of your own waves and wavetables.

The most underrated iOS synth of all time

Even if the sounds alias at very high octaves unlike Nave, there is barely anything that prevents this from being a great synth app. Although I used to wish for a classic/lofi mode (you can fake it with Ring Modulation and a bypass filter), I realized that this is not in fact supposed to be a PPG emulation or successor. This app is Mr. Palm's reimagining of wavetable synthesis from 21st century light. While Wavemapper and Infinite techinicaly sounds superior, the two-page interface and modulation and articulation of Wavegenerator are criminally overlooked. Did you know that this is one of the first apps to support the Linnstrument? Did you know that this is also one of the first apps to have audio unit support? Also thanks to Wavemapper and Audioshare, I have made Wavemapper a supersynth! I have proven that not only Wavegenerator can make modern PPG sounds, but it can also do FM, D50, and even Isao Tomita style sounds. Just be careful of how you use the aliasing. You can even make it sound like an Amiga sampler!

Don't understand it

Love the sounds don't have a clue what I'm doing but just moving things in GUI makes for interesting sounds the guys a genius but it's not rubbing off. Some day I'll look into it more deeply but now it's just fun and good sounds

One of my favorite synth apps

Dear developer, Thanks for reply! Setting to Left Handed (I’m right handed) fixed Spectrum Editor and Wave editor and they operate precisely now.

But the Arp and most importantly, Wave window itself is still broken. Impossible to draw a path or anything really in it. Squares are big enough for finger, but action occurs nearby and not easy to predict where. I wouldn’t use the Apple Pencil for this app, because I think UI is sufficient, but just for testing I tried it, and registers away from where you tap. Is it possible to at least turn this compensation off, as it’s not behaving as expected?

Love the app and UI, just hoping I can use it smoothly soon. Thanks!

Semi-original review:

3-star because there’s a bug introduced by the iOS upgrade that broke this awesome synth 😭😭😭

Bug manifests in 2 key places:

1) Wave Grid - you can’t change anything properly, even with an Apple Pencil.

2) Arptor - also completely broken in the same way. You tap in one place and the change happens one inch away.

Latest iPad Pro with latest iOS

Hope the developers will fix this soon. Can’t wait to dig into the depth of synth making! I’ll change the review and write a proper 5-star review, as the potential of this app deserves no less!

Developer Response ,

What you criticize here is designed to be this way.
How else could you edit something which is much smaller than your fingertip?

If the action would be directly under your finger, you wouldn't see what is happening.
That's the reason we designed it so, that the action is happening away from the actual touch position.
On the Spectrum editor you also could use the zoom, to get browder bars.

And, please note that on the Setup page you have a selector for Right/Left handed usage.
