Cality is a creative midi processor allowing subtle rhythmic enhancement, controlled chaos and everything in between. Add swing or accents, quantise the pitch of notes, use a probability gate or use the cloud module to add addition notes all under midi control The cloud section takes techniques common in granular synthesis and brings them to the realm of midi notes. It adds additional notes to the ones you are playing. This can be a simple rhythmic accompaniment or it can bring new textures from your synths by generating a cloud of tiny notes almost entering the realms of black midi. The note sections gives a fully automatable/midi controllable note quantiser with a range of scales, a transposer and the ability to constrain to simple chords as well The tempo section allows the addition of swing and accents to incoming midi notes as well as providing a probability gate Cality is great for bringing life to simple midi loops or patterns or for taking you deep into creative realms.
