Lilypond/Frescobaldi user since 2010. I also program in Java and have a decent bit of knowledge and interest in computer science, math, chemistry, etc. I can split / combine / transcode recordings and scores.
I really find great promise in IMSLP as a resource for all music-lovers to use, with its easy-to-use interface and immense collection.
"Kapurai Editions" means me. I just like the look of that on my typesets and audio compared to "Lekro."
