But why don't you just listen to the music you're making instead of just the sound? I can play an out of tune piano/organ because I'm listening to the music. You're doing the equivalent of reading Shakespeare and worrying about the quality of the print...as long as it's legible why worry about trivialities? Stop being so forensic and enjoy yourself!
'I certainly did not - I was checking: spectacles, testicles, wallet and watch...'
Obviously a very old joke, but I like it!
