ReaJS is loading successfully now. I do have a question, however. Typically in other VST hosts (Reaper, other DAW), you can load the same VST multiple times. I can't find a way to do that in MC. If I go to Manage Plugins and select ReaJS again, it's not added to the list a second time. Otherwise it seems to be working ok so far.
This is the included Analysis/gfxspectrograph script. This is from the Mobile Fidelity SACD release of Stevie Ray Vaughn & Double Trouble "Couldn't Stand the Weather" in the drum outro of "Voodoo Chile"
Top of the window is the nyquist rate (44100 in this case due to 24/88.2k FLAC source). You can't see the cursor, but I have it highlighting a portion of the splash cymbal showing there's -68.9dB at 25587hz. This recording has a great drum track, and you can see there's plenty of room in both dynamic range & frequency response to make it happen. Anything above the middle of the spectrogram would have been lost in redbook.
