There are lots of old MOD files out there which basically have random pitches for the middle C pitch, then have relative pitches on the patterns. For example, for a particular instrument, an E# note might actually be G, but for another instrument, a C note might be D.
I'd like to be able to change the sample's pitch to proper middle C, AND have all instances of that sample in the song automatically be corrected to what the note really is.
Why don't you simply use Search&Replace? You can search for all notes that match a given sample number and apply "note +/-1" and "note +/-1 oct" several times to get the correct transposition.
I didn't even know there was a Replace feature, since the menu command text just says "Search".
Can I assume that this request can be closed then?
