I've managed to create a snippet of music using my voice and on the whole it's ok, but I need to insert a note into a bar. The problem is the software doesn't let me. If I remove the two beat rest to make room for the new note it increases the note before and takes up the space I've made. If I try inserting the note after the rest it won't let me. I cannot seem to find any instructions on how to do this. Do I have to re-record the whole thing just to get this right?
