Sonic Synth is a new Universal iOS FM synth app with 3 oscillators and a unique interface. Unfortunately it does not support Audiobus/IAA. I spoke with the developer over the weekend and he does not have plans to add support for them either. He's considering AUX for hosting effects within the app.
Sonic Synth iTunes Description:
Sonic Synth is very capable FM Synthesizer app with 3 oscillators. Every oscillator is independent and can generate 4 wave forms. The app works with 44100 Hz sample rate so the sound quality is great.
The touch keyboard is very responsive and dynamic - feels like a real instrument. Keys are big enough.
The last wave form is our secret algorithm for string sound also generated by the oscillators.
Variety of sounds can be created and even changed real time while you are playing using the setting of the 3 oscillators of the synthesizer.
Sonic Synth main features:
- 3 oscillators
- 4 wave form types for every oscillator
- volume, modulation, tone and detune for every oscillator
- envelope filters (attack sustain release)
- fast and usable piano keyboard
You can now use your phone or tablet as a recording instrument.
