When i drag a sound (MP3) it become a FileMediaSource ! I don’t know why … pliz someone can help me !!!
Asset drag-n-drop is done by file extension. Media framework implements/looks for .mp3 file extension and imports as a media asset. UE4 doesn’t support midi decoding anyway. Only 16 bit .wave file import. Our documentation isn’t great for a lot of the new systems, but we do have documentation on this topic.
