Just got off the phone with Sweetwater.
They told me that we SHOULD be able to use our own MIDI with the TAP Search function. You need to import and have it indexed within the "User MIDI" section.
This is separate from the Browser area "My MIDI" where your third party midi shows up.
EZdrummer has a folder for "User MIDI". I don't know if you can just drag and drop your MIDI folders into that folder yet, or if you have to import them into the running box of EZdrumemrs 'User Midi" box, but that's WHERE it needs to go, to be indexed, supposedly.
So Toontrack is saying the Sweetwater we CAN use our own MIDI, if it's put into the right place. I won't be able to try it until later tonight at the earliest.
But just wanted to bring the good news, if it's true!
