Das Problem bei diesem Gig war nicht die verstimmte Gitarre, sonder der Einspieler des Keyboard Themes, das (einen Halbton?) höher war wie die Band spielt, und das lag daran, das der Zuspieler in 48KHz Samplingrate war...
...The synth is on a backing track, but the file's sample rate was probably 44.1kHz and the system's sample rate was probably 48kHz. Since there's a mismatch, the system sped up the track to match the sample rate. The problem was that Eddie and Wolfgang's instruments were still in the tuning that the song is supposed to be. Instead of stopping the show and rectifying the situation, they kept that trainwreck rolling....
