mtloo is a multitouch trackpad looper. It supports up to four loops and is meant to be used with Apple's multitouch trackpad. The parameters which can be controlled with the trackpad are: volume, playback speed, panning (2ch), effect feed (wet/dry), loop size, loop starting point, record new loop. For most of these parameters the user also has the possibility of saving and retrieving presets.
You can see the looper in action here. (mtloo+electric guitar)
It is shared here as an example of putting together various techniques in creating a basic user interface which allows a user to control a Max/MSP patcher using only Apple's multitouch trackpad for live performance. It is an example of putting to use some of the tools in the matra toolbox.
