I am so saddened by the news of Mark's passing.

Mark was a true genius and pioneer in notation software. His passion was to make music software that every musician could use. Mark did graphical sequencing in notation years before anyone else did By combining his vision for music making with his 30+ years experience doing software development, he gave a remarkable gift to us all that will endure. He was one of the nicest persons I've met and one of my heroes.

The world has lost a great man and he will be missed.

Our condolences to Mark's immediate family and his extended family that is this community.

In deep sympathy,

Gary Garritan
