hello!
this "map" is an "almost" full working minecraft wireless studio!
i made this map with ONLY command blocks. (no data-packs)





instructions:
when you first join the world, you will be greeted by a few things.
1. a row of note blocks (dont touch these yet)
if you look north, you will se a note block in the wall (click the note block)

2. when you clicked the noteblock, you will be teleported to a big room with an invisible floor.

3. go to the south/east corner, where you will be greeted with a few options.
and if you look down you will see a LOT of command blocks (these command blocks, represents each note of a "note block"
this little song, have i made to show what this studio can do)

4. simply type in chat
"/trigger start" and enjoy the little song
5. when a song is over, you click the message in chat.

6. to create your own song you will need to click "clear template"
7. then click "tp back" and choose the different "note block instruments"
you can do this by clicking the button under one of the note blocks.
then chosse the instrument by clicking one of the 16 note blocks, and accept the chat message.

7. go back to the studio by click the first note block again (the one facing north)

8. now you can start creating your song.
choose 1 of the 7 note blocks and after the pitch of the block.
when you have your sound go into chat and type "/trigger set_current_note".
now you will see 1 command block pop up under your feet.

9. you can also stack the note blocks by simply choosing another note.

10. when you think you are ready to go to the next part in the melody,
go to chat and type "/trigger continue".
11. now you will have to choose 1-4 ticks/delay. when you have done that, you then need to click the continue button that pops up in the chat, when you have choosen a delay type.

12. if you current delay isnt enough, can you click the "want to skip a note?" button and do the /trigger continue command again.
now another message will pop up, for you to select more delay.
