Let me rephrase that: If I get everything tuned, all harmonics OK, flashing strobe lights aligning and all, on this guitar, and then, on the tuner (GXTuner on the master bus) change from 440 to 441, it *does* matter much. Both perceivably (it's somehow worse that being plain out of tune) and visually, on the tuner's display. -- Yassin Philip - New album out NOW http://yassinphilip.bitbucket.org

To correct intonation the most used compromise is to ensure that the string has got the correct pitch when played open and when played at the 12th fret and when playing the flageolet above the 12th fret. For electric guitars this could be done by independently changing the distance of the bridge for each string. However, while the pitch then is correct for the open string and the 12th fret, the pitch for all other frets is never correct. Detuning a synth for even around a few Cents, even 1 Hz, could make a difference, as well as detuning the guitar, too make the guitars tuning correct for e.g. fret 5 or 7 of a string, instead of the open string and 12th fret. In my experiences some guitar tuners are a PITA and some guitar tuners are very pleasant. They aren't all the same. In my experiences when using a pleasant guitar tuner a guitar that is in tune when playing the open string and the string at the 12th fret, sounds good at 440 Hz with most synth tuned at 440 Hz, too. Some synth allow to chose the temperament. I noticed that while my guitar, DX7, Matrix-1000 and several other synth fit good when all were tunes at 440 Hz, my MT-32 with self made sounds, not the presets, often fitted better to them, when tuned at IIRC 439 Hz or something like that. If you even drop the low E string to D, you already need to adjust the distance of the bridge. When changing the distance, you usually need to adjust the high of the string, too. If your guitar has got a Strat alike classic whammy bar and you have mounted the springs in a way, that the whammy bar does not seat on the body, minimal different tension of the strings, cause e.g. by open tunings, makes the intonation, all your adjustments that fit to a standard E, A, D, G, B, E tuning, null and void. Anywway, assuming your Linux install shouldn't be fishy, the default for all virtual synth and plugins I ever used is 440 Hz. Regards, Ralf
