In the latest version of Minecraft, the noteblock can only adjust the pitch and instrument, but not the timing of the notes. My improvement plan is: the number of layers stacked along the Y axis of the noteblock determines the time of the note coherence [the duration of a noteblock Change to 1/32 time value of whole note (32th note)], the more the stacking, the longer the time value. After receiving the redstone signal, the scale box at the bottom level will connect up (not down).
When stacking a noteblock, it is the time value of 1/32 of the whole note (thirty-second note), and when stacking two noteblocks of the same pitch, it is the time value of 2/32 of the whole note (sixteenth note) , When stacking three noteblocks of the same pitch, it is 3/32 of the whole note (with dotted sixteenth note), ..., when stacking eight noteblocks of the same pitch, it is 8/32 of the whole note The time value of (quarter note), ..., when thirty-two noteblocks of the same pitch are stacked, it is a whole note, ..., when forty-eight noteblocks of the same pitch are stacked, it is 48/32 of the whole note Value (with dotted whole notes),...
When 32 noteblocks are stacked, the tone set for the bottom 16 noteblocks is la(6), and the tone set for the top 16 noteblocks is si(5):
At this time, the melody sent by the bottom noteblock after receiving the redstone signal is:
