Tuxguitar 1.1 supports polyphony

Until a couple of months ago, the only Windows proprietary application I needed on my GNU/Linux box was Guitar Pro, a shareware tab-editor available just for Windows and Mac. The free/libre alternative, TuxGuitar – despite the important benefit of running natively in Linux, that is without using Wine – could not satisfy me because it did not support polyphony. As I write mostly music for fingerstyle guitar, I do need to be able to display correctly the two voices (upper and lower) which define every fingerstyle piece.
