In this app you will assemble a song note by note in a sequential
List.
The List will be read back and used to play selected notes for a
specified period of time.
The Clock.timer element is used to time each note. The list is
stepped through until until a 0
placed after the last note spec is reached.
The design at left uses a vertical.arrangement inside a
horizontal arrangement as can be seen
at left with the vertical indented further to the right under the
horizontal.arrangement.
You should start by using completed lab 10 SAVE AS
musicRecorder as Lab 11.
In addition to all the blocks you already have from the lab 10
music box, you will need all the
blocks shown.
Pay close attention to the design layout in terms of the vertical
and horizontal layoouts where one
2 big vertical frames hold the music box from lab 10 and all the
elements of the recorder of lab 11.
This way when you make on Vframe invisible, all the elements

8 wav files representing 1 octave of virtual music box brass
reed notes are used to play simple songs.
!
In this app you will assemble a song note by note in a
sequential List.
The List will be read back and used to play selected notes

19. for a specified period of time.
The Clock.timer element is used to time each note. The
list is stepped through until until a 0 placed after the last
note spec is reached.
The design at left uses a vertical.arrangement inside a
horizontal arrangement as can be seen at left with the
vertical indented further to the right under the
horizontal.arrangement.
You need to upload 8 mid files represent the note of the
scale.

!
The report for this lab will be
combined with Lab 11 where a music
note recorder will be added to the
simple player app of Lab 10
