More than 260 Orchestra worldwide rely on OPAS to work efficiently and save time!

"We had a seminar in Lapland this mon-tues with all the Finnish music librarians and got to discuss about OPAS too, everyone who has this software already and been working with it for several years are very satisfied."

Essi Kinnunen Music Librarian,
Lahti Symphony Orchestra

"Every time I come up with something where I ask myself, 'I wonder if OPAS can do that?', it takes about two minutes and I find that sure enough, it's already there ..."

Jeffery Sells Director of Artistic & Orchestra,
Operations | Pacific Symphony

"Always a pleasure to work with you, everything is always solved very fast and professional, compliments to you all!"
