Aleksandar Mlazev, developer of Harmoinzer and Sonic Synth, has released Deep Synth : FM Synthesizer. This Universal iOS synth lets you create your own custom waveforms, which is going to be intense when you use them in FM synthesis! I'm going to have to check this one out!
While the app includes support for external MIDI instruments; it does not have AUv3, nor Audiobus/IAA.
Deep Synth : FM Synthesizer iTunes Description:Deep Synth is innovative FM synthesizer with powerful features.
You can create fully custom wave forms in real time.
The synth also has:
- simple envelope filter
- reverb effect
- tremolo sound effect
- hair - high frequency modulation.
- 5 points wave form modulation
- polyphonic keyboard
- 5 octaves range selector
- point vibe to make your wave dynamic

The sound generator inside the synthesizer is producing the exact wave form as the one you have created.
You can control the position and width of the picks in real time.
The synth app has fast and capable piano keyboard. It is fully polyphonic and you can play in 5 octaves.
Update: Here is a fun new demo of the app covering Seven Nation Army.
