I'm just getting back to midi music after a 15 year hiatus. It cost me at least $15,000 back in the day for just the midi portion of what Metro LE does, I'm still blown away with what my $69 has gotten me. This is my most recommended app ever. There is also a forum where the developer responds to virtually all posts. Simply incredible. All my questions and concerns have been addressed and I have had the best software purchasing experience of all time. Buy this software!
