The Matrix view is the new and exciting feature of Sonar.
You can trigger MIDI and audio loops.
I think the Matrix view has some similarity with Ableton Live kind of sequencing environment.
You can simply drag and drop any audio and MIDI loops in the matrix cell. Then you can trigger the playback for the entire column or row.
After arranging the cells accordingly, you can record the sequence while playback by altering the triggers.
This will be very useful for mixing artist, especially in the dance and trance genre.
I am getting a feeling that Sonar is going to dominate the computer music sequencing world.
More to come!
