Here's a little music player that I ported from this page:
 
It was not exactly easy to convert the code...
 
Anyway this plays his demo song with 4-channels of wavetable sound.
 
Actually, only the attack phase is wavetable, the rest is just decaying sine...
 
It sounds pretty good... Give it a try!
 
Update:  Here's a new version (xmasmusic7a.spin) that adds the other two demo songs from the above website...

This looks cool. Two questions though.

What is fullduplexserial doing?

How do you define what you want to play?

You can delete the fullduplexserial... That was just for early stage debugging...

The song is defined in the "melody" byte table. Just a cut and paste job from the code found on the page from the link in my first post.
It's just a simple series of word time stamps followed by bytes of notes with a bit to indicate the last note of the current time stamp...

I've just added a newer version to the first post that adds 2 new songs (and removes fullduplexserial dependence).

Hey Ray, Now you just need to add the midi object from OBEX and have it read .mid files from SD. :)

Neat player!

DMaskR long 0 'right output mask
OPinR long 10 'right channel output pin # ' <--------- Change Right pin# here !!!!!!!!!!!!!!
DMaskL long 0 'left output mask
OPinL long 11 'left channel output pin # ' <--------- Change Left pin# here !!!!!!!!!!!!!!

Is this player supposed to sound like piano or some other instruments?

Can I set both left and right to the same pin? ( I have only one speaker )

I think it was meant to sound like a music box...

just comment out this line:

OR DIRA, DMaskL

to just use the right pin...

Cool! I've wanted to make one, but never really figured out how to change the pitch without changing the playback time.

I am 1011, so be surprised!

I am thinking of averaging, but I'm not sure how to magically average it just right. Averaging is easy, but figuring out how to recursively average to achieve the desired result is the hard part.
