Okay, that what I wanted to know, if that definitely works for the solo for this particular song, because in most circumstances where I've programmed custom scales, they still need a momentary tweak because many harmonies are not as straightforward, and real world writers will switch rules depending on the situation. I know how the custom shifters work and what's available, which is why I kept writing that I'd need to see a transcription to see what would work for this song. If you know this song, then there's the answer. I've worked many times with songs where, when you play B the first time, you need one note to sound above it, but the second time you hit the same B, another note sounds above it. That's when you need something to tell the shifter that the rules change the second time you play that note.
Yes of course, if there is a very complex part in which a note is harmonized differently within a single piece then that must be accounted for. Like, a harmonizer even with custom scales is never going to be able to handle a true contrapuntal 2+ part harmony. That's not what the OP needs.
