MMIDE has an Applet that plays Ode to Joy.
On the CGMMSTICK1 the audio connection is NOT on J1 along with all of the port lines. Instead it is at the top of the board on an unpopulated header named J5.
On J5 the top connection is ground, the bottom (square) hole is the audio line.
If you have a small amplifier, you can connect the amp to these two lines and run the Ode to Joy Applet that is in MMIDE.

Using the Ode to Joy Applet in MMIDE to play a tune. |
The Ode to Joy Applet downloads a MMBasic program to the CGMMSTICK1 and then runs that program. Below is the program that is sent. You might notice that there is a test for data where the frequency could be 0. If the frequency is 0 no note is played, just a delay.
I asked my 15 year old son to write this program. He used a frequency/note chart to get the frequencies right, but the notes for Ode to Joy were in his head – he didn't have to look them up.
His frequency table was a little bit different than the table that I reproduced after the program below.

40 PAUSE du
50 ELSE
