there is, but let's be really clear first:
when we talk of 'drum maps' im reaper, we often mean the text file that you can load into the midi editor that shows the drum names on the piano keys... you can find more about that in the user guide... and also you can dl some for AD drums from the reaper stash.
It is also pretty easy to tweak those names to your own liking.
But I think you are talking about something else... like you have some GM midi files for drums but you want those to trigger AD drums properly instead... right?
There is a plugin that comes with reaper, called
JS: IX/MIDI_KeyMap
You create and load a text file into that... the text file tell is how to re-map whatever it is fed to whatever you have written in the text file.
for example, you can tell it to change midi note 36 to 35, or whatever...
Here is a short example of the start of that text file:
Quote:
//Key Mapping File. Change the number at the beginning of the line to set the output note.
//Octave 0
0 (0) C
1 (1) C#
2 (2) D
3 (3) Eb
4 (4) E
5 (5) F
6 (6) F#
7 (7) G
8 (8) G#
9 (9) A
10 (10) Bb
11 (11) B

The example is just the first octave but the one you will work with has them all...
The file you want is 00 - Default Mapping.txt, it's the template to start with.
[I may have renamed mine, but look for Default Mapping.txt]
Do a save as of that and then alter that copy.
Then you load your text file into that plugin, on the midi track that sends to AD...
