CelticPipes 2.0

Probably the most useful bagpipe software I have as it bridges BMW, PiobMaster and ABC compilers with ease, both for import and export. Its own interface is pleasant on the eye too. I use Lilypond for most of my own writing as it gives me excellent flexibility in compiling. However, so much is written in BMW and ABC, with a little open-source stuff in Piobmaster too, that CelticPipes is essential to me, and I use it often. Highly recommended.
