Annoydio has a grid of pads which you can assign, manipulate, and play sounds. There are several built in sounds you can assign to any of the pads. In the Library you can create your own custom sounds using your device's microphone. You can also add custom sounds through iTunes file sharing. You can manipulate the sounds by changing the frequency, playing in reverse, looping, adding effects such as distortion and delay. You can also change parameters such as attack, decay, sustain, and release. You can connect a MIDI keyboard and play the current sound with full polyphony. On the iPad version there is a popup keyboard. Annoydio also supports Inter-App Audio as a sound module and MIDI device. You can use Annoydio as an instrument to add beats or effects to songs in apps like Garage Band. Short demonstration video here http://www.youtube.com/watch?v=EzuQhLxMxeM

BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.
