Hi Linus,
at first i have to say: Great project and awsome tune!
I started to bulid one here at home but something is weird.
The controller seemed to run much to slow, so i switched to 8 mhz via ckdiv8 - now the contoller seems to run much faster... too fast... the tune is done in about 2 seconds...
Which fuse config did you use?

A case against syntax highlighting

To those who claim syntax highlighting is good/necessary/expedient in spite of the rationale in the original post, examine this:
http://www-cs-faculty.stanford.edu/~knuth/screen.jpeg
When your code is of quality >= Knuth's, go ahead and claim victory for syntax highlighting. Until then I too am doing without it...

You sir are a genius, this has got to be the most impressive display I have ever seen on an 8 bit MCU, hell it's better than what I've seen some (most) much more powerful MCUs do.
I happened upon this page accidently as I have been spending the entire day trying to find enough documentation to do some VGA stuff and I have to say that I am glad I did, you made my day.

I'm a little confused about the middle voice. I'm trying to figure this out using your process. Everything makes sense, except for the how the middle voice progresses. How does it start? I don't see how the circle for the first segment and the notation line up. Can anyone help?

Hey, great project. I've cloned your PCB but the Video doesn't work. Seems like Sync is broken. I've tried this with three monitors. Any idea? The colors seem to be right (they change) but no real video signal is visible.

Another strange thing is: The music does only play if the monitor is connected..

After circuit analysis I've found out that the 0V peak at the VGA-Sync Signals is acually at circa 1.7V. Are there any Port registers wrong and Pins not defined as output?

What was your fix? I'm still out of luck here.
Tried with CKDIV/8 and without.

Allt är möjligt. =) Man behöver något slags drivhjul med däck som får plats ovanför skenan, och så behöver man tänka ut hur man ska kunna gå runt hörn.

There is a known error, namely that AVcc has been left floating in my design. Since AVcc powers port C, this will cause current limiting on the RGB outputs.
However, I haven't had any trouble with the sync levels. Have you verified that there are no cuts or shorts?

Fixed it by myself. The compiler optimization produced crazy stuff. Bad results with -O2 but compiling with -O1 has worked great for me.

I patched your gui.c for my purposes:
This makes it a lot easier (at least for me).
You can change the current track with HOME and END keys
and change the instrument with PageUp and PageDown.
Hope that's okay for you, linus.
Great project - by the way. I've already started making tunes for your
platform.
