i dont know what any of those keys sound like until i place them and preview the whole song. in fl studio when you place a note or move it up and down it previews for you what the note sounds like so you know what exact key youre looking to play.
at 3:47 in this video is what i mean. when he creates a note at a key it shows him the preview sound of what that will sound like, but when i draw notes in music maker i dont get any preview. i have no idea what it will sound like until i hit play first and that makes things very inconvenient and slow.
im running the latest version of music maker
