XYXF is a free to download Max for Live device based around vector control. The device takes 4 channels of audio and allows them to be routed to separte corners of an X/Y, the pad can then be used to chop or mix between the sources. Add different effects to tracks containing the same audio such as bass and morph away. You can modulate the X and Y controls using Lives LFO devices or midi map them as you wish. Have fun and Make Some Noise!
