Peter Simons, Owner of IdentiTree

“Jan created Arbora 1.0.0 tree management software according to the "Extreme Programming" concept. In short time and budget we realised lots of functionality. It was great and inspiring to work with Jan. Arbora 2.0.0 is our next goal!
Top qualities: Expert, Good Value, Creative”

Ron Arts, Owner of Netland Internet Services

“Jan is a very skilled programmer, and a very nice guy to work with. It was a pleasure to have him in the team (if only all programmers were like him). I was sorry [when] he left our company, and still am. Highly recommended.“

Heikki Junes, Business Analyst, Scientist and LilyPond developer

“Jan is a bright person who has brilliantly kept the core of LilyPond in hands.”

LilyPond referenties

LilyPond is my best reference by far. We get many, many thank-yous on our mailing lists.

Paul Davis, developer of JACK and Ardour

“I think [LilyPond is] an incredible program, and it produces wonderful, wonderful output. When I read an interview about it last year, I was raving to several friends of mine about its potential.”

Carter Brey, Principal Cellist, New York Philharmonic

“… I’ve written a couple of encore pieces for solo cello which I’ve printed with LilyPond and which I’m going to submit to Schirmer for publication. I’ll bet their engraved version wouldn’t look half as sharp as mine!”

Dr. Mika Kuuskankare, researcher at the Sibelius Academy Finland, composer and author of Expressive Notation Package (ENP)

“I have the deepest respect towards LilyPond and towards its creators and maintainers as I know from personal experience how difficult this kind of software can be.”

David Cameron, Musician, professional typesetter and long time SCORE user

“My heartfelt thanks to everyone who contributes to this project. I was a power SCORE user for big typesetting houses way back in the '90s, but I feel LilyPond finally makes it possible for me to get exactly what I want on the page, especially when it isn't "standard" practice.”
