Ever had the problem remembering which tracks you already had played after several hours of DJing?
This device changes the color of a playing clip and adds a prefix / suffix to the clipname after a predefined period of time, so you can easily recognize which clips have already been played.
In addition, it also keeps track of all played clips in a playlist (which you can export as a textfile).
This device has been made available thanks to the Japanese Sound&Recording magazine as part of an ongoing series of articles about artists using Max-for-Live devices:
