let mut builder = MidiEventBuilder::new(0x91);
assert_eq!(builder.shortage(), 2);
builder.push(0x00);
assert_eq!(builder.shortage(), 1);
builder.push(0x02);
assert_eq!(builder.shortage(), 0);

let mut builder = MidiEventBuilder::new(0xc0);
assert_eq!(builder.shortage(), 1);
builder.push(0x00);
assert_eq!(builder.shortage(), 0);
