Hi
I compiled latest linux version pianobooster Version 0.6.6.svn.31-7-12 on Ubuntu 12.04
Binary attached.
Download the binary attached here
pianobooster and copy to /usr/local/bin/pianobooster directory
Start it with --lights parameter, so you will have led lamp guide (only if your piano has led lamps :) ) which is the most fun part of PianoBooster!
#pianobooster --lights
Have fun. :)
