Re: Two voices in two different colors, which color wins in unisono part?

[Jan Warchoł]

Hi Jurgen,

the strange coloring interested me, but your snippet failed to produce
any output on my computer... Also it collapsed into a continous stream
of characters (see below) which renders it totally unreadable :(
Perhaps something is wrong with your e-mail client?

cheers,
Janek
