Love the piece - as a flautist I'm very interested in celtic (or at least celtic-sounding!) music, and I've come across few good pieces like this - slow, relaxing and beautiful. If you can, track down some recordings of original compositions by the Christian flautist Simeon Wood, particularly the 'Across the Blue Sea' album for some similar stuff.
Is the piece available in sheet music form? I'd be interested in playing it.
One comment though - MIDI bagpipes are all very well, but many of the common varieties of real pipes are not tuned to the standard western scale, so you may have difficulties with tuning.
Thanks again!
