Just discovered an awesome program called #Polyphone. It's a tool for creating your own Soundfonts for MIDI devices. Basically you supply audio samples and tweak it into something your piano keyboard can play.

If you're using #LMMS and feel apprehensive about using "royalty-free" #soundfonts with ambiguous sources (a grey area for some musicians), check out the prospect of making your own instead!

It's licensed under the GPL, and works on Windows, Mac, and Linux!
