If Jack gives problems try portaudio backend with the "-b portaudio" option. In the next release we will default to portaudio backend. > Also, I tried playing found chords on guitar and it seems to me that > displayed chords are one semitone lower than the sound that is playing, > but maybe just I didn't tune guitar right (can't find tuner right now :)). Also a bug which can be workarounded. We are not using any samplerate conversion. The algorigthm is tuned to run at 44100 as most wave files. Jack might have been configured to run with 48000 so you are probably hearing the song a semitone higher than it is. Portaudio backend fixes the output samplerate to 44100. > Other than that, some changes are needed for compilation on Arch linux, > so a little tutorial follows: > > I checked out whole CLAM svn (svn co http://clam-project.org/clam/trunk > clam).
