What is the max size wav file the BB can use for a sample? I am thinking about putting together a kit that uses Ambient pad sounds for texture. These are used frequently in Worship music, and right now I trigger one that just plays in a set key throughout the whole song to create some ambience. In that use the files are pretty big because they are Wav files that are 7 minutes long. Can someone let me know the limits as far as file size and time length?
