Been there done that. But good for you it giving it a best try. That is the way you learn.

Here is a thought, now that you have the "...perfect rendition of the MIDI BUT, of course, as audio and not MIDI", put Melodyne Editor (preferably Editor or higher) and it will convert the entire audio track to midi. Then export the midi and import it to another Reaper Track. You may be pleasently surprized.



Best of luck.
