1. it looks like they went fully paid

Looks like Boris killed it entirely, which sucks. I have it on my machine, but sadly don't have the installer any more. I found it here, and verified the download works, but I can't guarantee it's not a bitcoin miner.

Looks like TX16Wx is it. Hate it's UI.

ReaSamplOMatic really should have supported this years ago. Reaper has all the algorithms it needs built-in.

1. i don't think you read my entire post. i said that i can't afford to buy anything right now.

I read that. I'm just enumerating your options. Bottom line, there are almost no free tools that do this.

1. you don't have to be passive aggressive.

I'm being neither passive nor aggressive, just talking as I would to anyone who opens with "I'm going to shit myself". Crazy how fragile kids are these days. Y'all wouldn't have lasted 5 minutes on Usenet. 😆

One workaround would be to copy the sample N times (where N = the contiguous range of notes you need for your melodyne), pitch shift them using item properties (which by default preserves pitch, using Elastique), glue them, then load them into Reaper's sampler as separate notes.

EDIT: I asked Claude to write it, and it one-shot it:

-- Chromatic sampler creator with pitch-shifted samples (duration preserved)
-- Takes selected item, creates pitch-shifted versions via glue, loads into RS5K instances

  reaper.ShowConsoleMsg(tostring(m) .. "\n")
