(or translate CC#64 (Sustain) to CC#66 (Sostenuto) for example)

For example, we convert aftertouch to CC 75, that understands REAPER learn:
(If you dont know (for example) how to install ReaPack, just google it.)

1.First step:
Use "Midi convert to CC", (that avaible after installation through ReaPack, which need to be installed first) Add this FX into your track "INPUT FX" and configure:
Choose midi message you want to convert. (Midi Message) (For example Aftertouch)
Then choose command you want to use with REAPER learn. (Out CC#) (For example 75)

2.
Add* VST plugin "MidiToReaControlPath" to your track "INPUT FX"
* Always add "MidiToReaControlPath" last in list, if you dont, it may not work, so drug and drop it into the end of FX list.

3.Now you can use REAPER learn with non CC message, that now, repeated to the CC message, which y're configured. (Aftertouch to CC 75 in our example).

Thx mschnell for manual.
Ver 0.99b


Bonus:
You can use aftertouch instead of two pedals in the same time for example, let's convert it into sostenuto (CC 66) and Una Corda pedal (Soft pedal CC 67):

1.
Use "Midi convert to CC", (that avaible after installation through ReaPack, which need to be installed first) Add this FX into your track "INPUT FX" and configure:
Choose midi message you want to convert. (Midi Message) (For example Aftertouch)
Then choose command you want to use with REAPER learn. (Out CC#) (For example 66)

2.
Use "Midi CC Mapper".
Add this FX into your track "INPUT FX" and configure:
Choose midi message you want to convert. (Controller Source) (For example 66).
Then choose command you want to use with previous command (Sostenuto with soft pedal). (Out CC#) (For our example 67).
Change parametr above: "Pass Through CC Source" to "Yes".

3.Enjoy!
*For additional pedal (or other command) you have to use additional "Midi CC Mapper". (Config it like in previous example).

Thx mschnell again.

After Touch (aka Channel Pressure) is not a CC, see -> https://www.midi.org/specifications-...f-midi-message .

I think I will enhance "MIDI convert to CC" (available via ReaPack) to be able to convert channel Pressure....

I translated this topic into the manual and this is what used to be here instead of what is now (a little history):

Why i want it?
Because my novation impulse 61 have not plug for connect Sostenuto pedal (CC 66).
So, i want to press note, and with aftertouch emulate sostenuto pedal pressing for this note (or just sostenuto pedal).


May be it will be somehow helphul for man, who looking solution (not help to me, i'am beginner, so can't use it yet):

Quote:
"for midi control, Reaper gets the midi directly from the input port (loopbe in this case), so any midi processing you do within Reaper won't be used for its midi learn system.

to (sort of) do it all within reaper, you could have one track doing the conversion and sending it to a virtual midi port, which would be received by other tracks.

otherwise, i would say you should request that channel pressure be added as a midi control source in reaper."



Maybe there there is a REAPER Feature Request suggestion which I could vote?

So, to to get things done, need to use something like this?
"JS for CC to Program Change converter?"

Hope an easy solution will ever appear.

desc: MIDI convert to CC
author: Michael Schnell (mschnell@bschnell.de)
version: 4.1
changelog: added After Touch
donation: United Nations Foundation http://www.unfoundation.org/
about:
  ## Description
  
  Midi CC, PC, Note On or Note Off messages are converted to Midi CC messages with a predefined Channel and CC #. The CC value is calculated from the incoming value. 
  
  All midi messages that don't fit the "In" specifications are passed through.
  
  The slider "In Channel" defines the channel the messages to be converted are expected in. "all" accepts any channel.
  
  The slider "Midi Message" selects if CC, PC, Note on or Note Off (Note number), Note on or Note Off (velocity), or Pitch bend are to be converted. With Note off, also note on messages with velocity 0 are used. With "Note On Velocity" beware that some keyboards send Note On with velocity 0 as Note Off message, so set the Min Input Value to 1. 
  
  The slider "In CC" is only used when "CC" is selected and defines the CC# of the eligible input messages.
  
  The sliders "Min Input Value" and "Max Input Value" d3efine the range of the eligible input values. When using Pitch Bend as an input, 0 .. 127 is converted to 0 ... 127.9921875 is converted (and 127 exactly is converted to  127.9921875 for convenience), and  it might make sense to tyoe in an exact value.
  
  The slider "Out Channel" defines the channel the converted messages are sent in. "same as received" reproduces ses the channel as received, as well dedicated in channel mode as when setting the in channel to "all" .
  
  The slider "Out CC" defines the Midi CC message # to be sent
  
  The slider "Min CC Value" defines the value to be sent when the Min Input Value is received. Hence there will be an offset of Min_Input_Value - Min_Outout_Value. 
  
  The slider "Max CC Value" defines the value to be sent when the Max Input Value is received. Hence there will be an appropriate stretching of the input range. 

  TODO: hysteresis with Pitch Bend input.

  (When testing beware that the JS: Midi Pitch Wheel LFO erroneously outputs Databyte 1 values > 127 ! )

Iam trying to find manual, how launch this)
Iam really beginner in this)

Its probably ReaScript, so ive install it, and tryed launch your code, but
"
midi to CC.lua:1: function arguments expected near 'convert'
"

So i keep trying look into it, to make it work.

Sorry for not providing instructions !
In the end this will be updated on "ReaPack" and same will automatically install it on request, but uploading to ReaPack takes some time and I wanted to get you going (and testing) right away.

You need to create a text file (using some text editor) with the code above pasted into it ans save the file with an arbitrary name (and e.g. no extension) in c:\users\your_user_name\\appdata\Roaming\REAPER\Effects\ (or open the directory in Reaper by Options -> Show Reaper Resource Path...

After that you can load the effect "MIDI convert to CC" in any track's FX chain.
