Passing files (WAV,etc) to REAPER works fine, unless the filename contains the '#' character, then the file isn't added correctly. Seems REAPER is trimming the filename after the # char, so if I try to pass a file named, "64_Hat_Clsd#2__RR4.wav", REAPER adds an empty/offline item named "2__RR4.wav".
Also, when adding items this way nothing is added to the UndDo History and REAPER also doesn't know anything has changed, so you could possibly exit REAPER and loose everything added.
