[LAU] looking for a jack-enabled "guitar tuner"

Hi I work quite a lot with music made from samples. To ease the process of tuning samples, I thought "there might be a good linux tuning software outthere", but couldn't really find any, maybe because I don't know what to type in google :-) I found http://linux-sound.org/guitar.html and also looked at fmit and tuneit, but all seem old and a quick build of the two most interesting apps, fmit and gtkguitune, failed (we can dig later if those are recommended apps). So I'm looking for a recommendation: Which jack-enabled software could help me tune samples? If it doesn't get confused when the sample contains more notes, like a chord it would be great! NB: Sorry if I overlooked something obvious, I never worked with software of this type before... -- Atte http://atte.dk http://modlys.dk http://virb.com/atte
