Yeah I will have to agree with this. The loading of your own IR is almost a joke. I have a lot of mine sorted into different folders nested inside folders and on and on. I have 44k, 48k, 96k, Halls, Rooms, Plates, Churches, and on and on. All in folders. I have to open every folder to put them in the "User" option of ReMatrix. After loading about 20-30 IR, I quit. It wasn't worth the time.
ReMatrix does sound good though. But being a "lite" version, I think we got what we got and that's a wrap. : (
