Although I admire your determination for and devotion to FLOSS, I'm not currently satisfied with the tools and especially instruments (real instrument "recreations" or electronic).
I do not mean to offend the wonderful efforts done by the community already: and I would like to point out that there are significant projects that I use to make music.

But in the end of the day: I have to put more effort into getting the sound I want using linux tools than Mac or Win. Although its very honourable to only support FLOSS, I also want to make music that sounds *great* not just *good*. If paying for instruments like Modartt's Pianoteq, then I'll do that. It sounds *wonderful*, not like a 90's MIDI Dance piano.

With that said, I'll get back to reading the rest of this thread :)
