Non-standard Pitch & Tuning

I think your best bet would be to record your own tuning tones. You should be able to use a software instrument to record a pure tone for a few seconds and pitchbend it to your needs.

While it was for A440, there were several suggestions on how to do this sort of thing for GB1. Does anybody remember what I am remembering? Or are we all too spoiled with the built-in tuner?

If you have a US-122, the supplied software tuner for that will let you change the pitch from 430 to 450 Hz. (I guess any of the TASCAM US-XXX boxes have the same tuner...)

It just seems that, because the accordion is the only out of tune instrument, a plugin in to raise the pitch of the recorded accordion track would be the easiest. I have seen a few plugins but these are in the $299.00 range which seems pricey for the simple thing he is trying to do.

Anyone know of a cheaper alternative?

Can you tune an accordion? According to internet sites on the subject it ain't easy!

sure enough! It most certainly does. I never used that tuner since I got the US-122. I was quickly able set it to 438. But that is only good for instruments you can tune. The software instruments in GB are another beast altogether.
