This is first mix of an Orchestral work I wrote 6 years ago. Used Reaper 6.12 for the mix in July 2020.
I used Reaper's MIDI editor extensively to modify (and "draw in") the CCs, channel pressure, and mod wheel values of several instruments.
1. The work was written 1st in Finale.
2. Finale exports MIDI data: one instrument per MIDI channel.
3. Reaper imported the MIDI data flawlessly. Pow! Dozens of MIDI tracks appear.
4. Organized MIDI tracks by instrument groups: woodwinds, brass, strings, percussion. Each group got a master MIDI track--I added a multitrack FX to Garritan's Aria player which I loaded with the MIDI-to-audio sample instruments.
5. Used Reaper to generate output tracks for each MIDI track. Ran these tracks to Reverb tracks.
6. After editing the MIDI CCs, automating volume, mod wheel, etc parameters, I created STEM tracks by instrument group.
7. Created a jpg image track to include conductor's score in time sync with the music.
8. 1st master mix is posted on Youtube with jpg images of the score.

Final talley 98 tracks.
Any professional criticisms or suggestions very welcome.
