this is a new plugin i'm working on. it is to serve as the basis for my new scratch engine to be used with my ipad2, mac, osc, and kinect. i just finished the recording plugin and this is the playback component. the great part about this component is that it is made with quartz composer, so now i can add waveform visualizations and video effects plus plugin anything from the kinect to midi.
next is to add is the 3d audio eq, and audio effects nodes. this way i can use a track ball to control the 3d eq plus use the same parameters to drive the audio effects. in addition to auto BPM i would like to add auto sync and auto key finding.
seeing i am using audio unit hosting.... pulling up a component effect or instrument unit that you have will allow for additional audio tracks to be mixed with generative and reactive visualizers.
