I'm interested in getting Reason, but I am not sure if it can perform some of the functions I would require. I noticed the demos which use the Matrix only play one tonality or one chord phrase. Does it respond to chord data so I can have a song have different chord changes which follow the Matrix phrase pattern (like an arranger keyboard)? Or do I need to load a seperate Matrix phrase pattern for each seperate chord change? All the demos are done in a one-chord style so I'm not able to determine this.
