[linux-audio-user] Tuning Program or wav files?

Folks, I've got a early Holiday present in the form of a new violin. While my eventual aim to to put a pickup on it and start playing around with MIDI, i have to get it tuned first. I don't have a pitch pipe or piano handy. I have a very accurate (musically) system set up, of which my computer is a major part. I'm looking for wav files or a tuning program that would help me tune this violin. If i had a wav file or a tone generator, I could just put it on repeat while i was tuning. I've been searching the web for an hour now and have found nothing, but i may just be looking in the wrong places. The starting point for a violin is A (440) then D, then G then E. All are a perfect fifth apart. For the record, i use KDE mostly, but have the gnome libs installed in case anyone has a good app suggestion? Anyone out there able to help? Much appreciated, Bearcat M. Sandor
