first gigs!

[Mike Spalding]

Charles,

Congratulations, and well done!  It's all about learning from your
experience, isn't it?

Regarding the generic tuning curve for bringing notes up to pitch before
sampling, doesn't Tunelab come with a tuning file named "average", along
with some other sample pianos?  Any of those would get you close enough for
a valid sample, or even a valid pitch raise from 120 cents flat.

regards,

Mike Spalding RPT
