1. First when Magma tells me to put audio for the song, i'm obligated to put in for all instruments the song has authored. Is there a way to include just one audio with no silent audio?
2. Second when the actual song is built, it is 51.4 mb large. I use the wii so I cant run any songs that are larger than 40 mb. The song is 40 minutes long but it only has guitar and drums. Is there any way to make it smaller while keeping it the same length?
