How to control individual MIDI STACK tracks from wihtin REAPER

You would probably only need to do this if you wanted to save a Reaper project and run the individual MIDI tracks from REAPER - perhaps you have additional effects and instruments that only work within Reaper.  Otherwise there is an alternative method for making changes to a Type1 MIDI file that is details here....

Open Reaper

Double-click roughly on the left hand side of Reaper to create a track. Reaper doesn't care if the track is MIDI or VST or AUDIO, a track is a track !

Click the "FX" button within the track
A large list of available plugins is listed.. double-click on the Unify VSTi. This will open up Unify and load it into that track. If you don't see Unify listed you may need to look at the options, preferences, plug-ins, VST and click "edit path list" to add the location of Unify then "re-scan" the VST's.

Close out of the Unify VSTi just so that we only see the Reaper window - in the track box double-click in to the black "name" area just to the left of the "FX" button and write "UNIFY VST" as the name for the track containing Unify.  Naming this track is going to help out later on when we add sends to the MIDI tracks.

Click on the "FX" button again to open up the Unify VSTi.

Find a patch that contains a midi STACK... for instance...
PlugInGuru CloudCity V1 - BPM DRUM - Hip Skip Welcome To Miami -- this is a Unify patch with a 25 track MIDI STACK file....

Click the transport button in Unify to see the original Tempo for this patch (it is 90BPM)

Step2 - locate the MIDI Stack File in Unify.
2a.. Click the "B" on the MIDIBox containing the STACK mid file to bypass MIDIBox (important for editing in Reaper - the bypass button should now be light grey with a white "B" to tell you it is bypassed).
2b.. Double-Click the MIDIBox containing the STACK mid file
2c.. Click onto the light blue name of the midi file (this will open up a file system dialog roughly in the location where Unify looks for MIDI files for this patch).
2d.. Resize your file system dialog so you can see MIDIBox
2e.. in windows file manager.. type the name of the midi file (the light blue name) into the search box and press the arrow box to search
2f.. The midi file will be found and hilighted.

Step3 - Edit the STACK in Reaper
3a.. Just above the Mixer are the controls for recording and playing.. look to the right of those and you should see the tempo BPM.. If it says 120 just click into the number 120 and change it to 90 for these examples.
3b.. Drag the hilighted midi file into Reaper (into the track below Unify if Unify is a VST) but don't release it until the beginning of the midi file is shown at position bar 1.1.00
3c.. Look at the "MIDI File Import" dialog. It will have a checkbox ticked - "Expand 25 MIDI tracks to new REAPER tracks... click "OK".
3d.. If you have Unify as a VSTi in Reaper then look at the bottom of Reaper at the individual tracks. Click on the individual "Route" icons in the Mixer at the bottom of Reaper for each of the STACK TRACKS and click where it says "add new send" then look up the list of available sends and select send 1 (this should where Unify VST is loaded and if you named your unify track it will say "UNIFY VST" in send 1). Close the Route Dialog. Do that for each of the STACK Tracks that you want to edit otherwise you won't be able to audition or hear the edits.

3e.. Single-click onto one of the MIDI tracks to hilight just that one track. Double-click into that track to make MIDI edits.  Do not double-click when more than one track is hilighted as it will merge hilighted tracks as a mess.

3f.. If it looks all "scrunched up", to the bottom right of the MIDI edit screen is a "+" control so you can stretch apart the notes to fit better on the editor. There is also a scroll bar on the right and a MIDI Piano roll on the left. You can click into the Piano to hear where the drum beats are located. There are some buttons on the top of the MIDI editor and three of them have MIDI symbols with Block/Play/Diamond so you can change the look of each note in the editor. Diamonds are normally for drum edits.

4) have fun!

5) after you've had fun, within the MIDI editor... at the top left of the editor click "File" the select "Rename MIDI Take" and call it what you want followed by ".mid"  (unfortunately this will only remember the name you choose within this project and it won't get saved to the MIDI file when exported... I will raise a support request to find out why the rename function doesn't work - the MIDI edits are remembered)

6) If you still have Unify open, close the Unify VST

7) In the grey area just beneath where it says "UNIFY VST" Select the track where Unify VST is loaded and hit the delete key (we only want the MIDI tracks in this project).

8) Delete any MIDI tracks you don't need (just keep the tracks you edited and the tracks you want to keep in your new STACK).

9a) Top left of REAPER click the "File" menu and near the bottom of that menu click "Export project MIDI"
9b) Consolidate time: Entire Project
9c) Consolidate MIDI items: All
9d) Multitrack MIDI file (type 1 MIDI file)
9e) take note of the "Export to MIDI file" location and name and use the "Browse" button to save the midi file and rename it to whatever you like (needs ".mid" at the end of the file name).
9f) OK out of the "Export Project MIDI" dialog

Just so you know... renaming the individual midi stack takes in Reaper doesn't work - all of the original midi take names are always remembered. This must be a bug with Reaper. I will raise a support request.

That's OK though, the MIDI edits are remembered.

There is an alternative way for just editing MIDI tracks and it does allow renaming of each track...

Close out of REAPER
Save the Project if you want.

10) open up the file explorer and navigate to where you saved your midi stack file, copy the file and save it to your PluginGuru Unify Libraries User Library (create a MIDI directory/folder if you don't already have one)

11) now you know your edited MIDI Stack is in your Unify User Library.... open up the standalone version of Unify

12) In this case I'm going to open up the patch PlugInGuru CloudCity V1 - BPM DRUM - Hip Skip Welcome To Miami

13) double-click into the MIDIBox where the original STACK is located

14) click on the light blue name of the midi file and navigate to your user library where you saved the midi stack. Select the edited MIDI Stack file, and click Open.

15) Apart from the stack take names being incorrect!, you should be able to use the pull down menu or in this case you can use the "25 Patterns" macro knob to cycle through your edits.

Hopefully soon Reaper will be fixed and remember the names of the stack takes.
