Redshrike is a polyphonic synthesizer that combines a resonator designed to make more complicated sound creation and subtraction synthesis with an FM oscillator that creates violent distortion.
The oscillator has frequency modulation at a wide speed from low speed to the audible range, and it is useful for creating dirty sounds together with the resonator.
The waveform of the oscillator can be morphed from sawtooth wave to triangular wave and square wave. In addition, the oscillator has a 3-voice waveform generation engine internally, and you can make a thick sound by detuning it.
In the resonator, not only feedback amount, but also its pitch can be modulated with ENV and LFO. Musical distortion is added to feedback, and it can produce from warm sound to screaming sound.
The filter has a Low parameter that can boost the bass range, and you can make a heavy sound.
Redshrike works not only on the iPad but also on the iPhone. It also supports Audio Unit Extensions (AUv3), so you can plug in to AUv3 compatible host. For each screen size, different layouts are designed to be easy to use and intuitive.
