Synthia is a small but powerful polyphonic synthesizer for the iPhone and iPod Touch.


A bank of cascaded-triple-oscillator frequency modulation (FM) synthesizers provides a broad palette of sounds from percussion to strings with over 170 million variations.

The keyboard can be scrolled across the full 88 keys of a piano from A0 to C8. You can even change the size of the keys to suit the size of your fingers. The keys are touch sensitive - the harder you tap a key the louder the sound.

There are 14 synthesizer controls:

Amplitude attack

Amplitude decay

Register (octave) shift

Portamento (for "sliding" from note to note)

Modulator 1 attack

Modulator 1 decay

Modulator 1 frequency ratio

Modulator 1 modulation index

Modulator 1 and dynamic modulation

Modulator 2 attack

Modulator 2 decay

Modulator 2 frequency ratio

Modulator 2 modulation index

Modulator 2 and dynamic modulation

The FM frequency ratio defines the harmonic frequencies, modulation index controls the number of harmonics, and dynamic modulation defines how the harmonics change in time.
