Roland R-MIX lets you see the components of a stereo mix as color-coded clouds of energy and harmonic matter as the song plays. Download the free R-MIX demo and you will be able to select your desired components of a mix, and freely edit them — an impossible task in the past. You can even change panning positions and levels to individual instruments within a stereo mix for example. This gives you the ability to add effects to each element as desired. R-MIX also allows you to independently adjust the pitch and speed of the playback..
