I've written a free utility that can batch process MIDI files to change their drum mapping. Change the number at the beginning of the line to set the output note. 'c:\Program Files\REAPER\Data\ix_keymaps' Maybe you will have to expand the mappings, since I've included only basic notes).ĬOPY TO NOTEPAD, SAVE AS TXT AND COPY TO: I've done a simple remapper AD->GM for a friend, so he would know how to do it. You just have to know both mappings (GM & AD). You can prepare the file in Excel and save it as TXT and copy it to Midi_KeyMap preset folder. Their website but I guess nobody has come up with a way of doing this in REAPER yet. They do have maps for Cubase and Sonar on I haven't been able to find anything on this either here or on the XLN Audio forum. Is there a way in REAPER to map GM MIDI files to Addictive Drums (full version)? I would like to use my extensive MIDI library in GM format along with the MIDI grooves provided with AD.
