ShapeSynth is a powerful polyphonic synthesizer designed for iPhone users. Developed by Erik Sigth, this full version software falls under the Multimedia category, specifically Music & Radio.

At the core of ShapeSynth is its innovative feature that allows users to draw the shape of the oscillator waveform. With 32 blocks representing the first half of the oscillator and its mirror image for the second half, ShapeSynth generates a wide range of raw retroish sounds. The ability to interpolate between different shapes using the 16 pages per oscillator adds even more versatility to the sound creation process.

ShapeSynth offers a variety of features to enhance your sound. You can add effects like arpeggio, stereo delay, and a resonant filter to further shape your sounds. The software also allows you to record your creations on a classic tape, offering infinite overdubs.

Modulation is a key aspect of ShapeSynth, and you can easily modulate any parameter using the keyboard, MIDI MPE, or the device accelerometer. This opens up a world of possibilities for creative expression.

In terms of connectivity, ShapeSynth is compatible with other apps through AudioBus, IAA, AUv3, and MIDI. It also supports Ableton Link and AUv3 host sync for seamless integration with your existing setup.

Overall, ShapeSynth is a unique and powerful synthesizer for iPhone users. Its ability to draw oscillator waveforms and its extensive modulation options make it a versatile tool for musicians and sound designers alike.
