I couldn't manage to compile them, but the specs & screenshots seem great: - KGuitar (a Tse3 / KDE Guitar-Pro Clone) http://kguitar.sf.net (not Jack-aware - it couldn't detect properly that aRts server) - LegaSynth (a Yamaha DX7 FM / C64 SID / Sega GENESIS synth) http://www.reduz.com.ar/cheesetronic/index.php?section=4 (libsigc++ installed but not detected?!) Bad idea(s)?
