Hi @jfa - yes, it was your script I was referring to 
Really nice job on that, and extremely useful. One suggestion for future development - and I really have no idea how difficult this would be - would be to introduce a random few milliseconds shift to each harmony, either before and/or after the beat to prevent phasing issues if using the same voice bank for main and harmony.
In Cubase I’ve found that moving similar audio clips on different tracks 1/128 or even 1/64 before or after the beat can help phase issues with no discernable effect on the timing. I used to use this idea to reduce phasing, but I now rely on the Fuser plugin from Mastering The Mix instead.
But anyone using SV in standalone without a DAW might find this a useful addition.
Just an idea from someone that doesn’t have clue one about the scripting language!
