Titletune help

[Grevle]

My game Dracula Story is only missing a title tune , and i'm no musician. So i have a simple two tone music engine ready. I't Plays two channels pokey clearnote.

It reads Byte in this format  Example .BYTE $0,$58,$50,$55,$50,$60,$40,$40,$60,$50,$55,$50,$60,$70,$70 - For channel 1 and one more like this for channel 2 with is normally the bass notes.

 

Not to long tune. perhaps max 60 notes.

 

Setting $0 shuts off  that channel until next note is set . useful for the bass note mostly

 

Tempo is controlled by having two of the same notes after each other. then it will play that note twice as long

 

All i need is the right byte data for a fitting titletune. 

 

Anyone have some data like this i can use ?

 

 

 

Thank you.

 

Tried make one myself. The most annoying tune. lol

I'm not a musician, but check out the book The Musical Atari and you'll find several tunes that are easy to convert to assembler. 😉

What do the bytecode mean in musical notation? Is there a chart for notes?

[ivop]

It looks like your data are just frequencies and zero is silence?

 

For a spooky sound track to fit the Dracula theme, try something in the Phrygian scale of E. On a piano, that's playing from E to e on the white keys. Very simple, but not your regular do-re-mi.

 

E F e f E F e f is a popular spooky motive. Or f e B F E. That one is used a lot in TV Shows, like Who Wants to Be a Millionaire?

 

If you share the source of the small player, I might be able to come up with something.

 

 

Edit: and E F E F repeated ad infinitum is Jaws

Thanks! Is there a reason why you don't just use RMT or another music tracker?

Yes. Out of memory. Turbobasic is used for some setups and to draw the backround still images, Then all gameplay and sfx and such is Assembler. Combined it uses a lot of memory.

I see. So how many bytes do you have free for a player plus data?

Hmm around 200 bytes max.

O wow, that's really limited. I could do some notes, but that would be it. Or generative music like I did in several size coding competitions.

 

I'm about to watch the cyclocross in Fayetteville (USA), but after that I might do some experiments and try to keep below 200 bytes.

 

For the record, you boot Turbo Basic, do some initialization (I assume lots of pokes?), pre-draw some images, and then run your assembly code? Does it ever return to Turbo Basic or is it all assembly after that?

 

I'm asking, because the pre-drawn images could be dumped as a binary file, and the init code is probably easily ported to assembly, which would bring you to the 100% assembly realm and more free memory

 

But maybe that's too much work. And I like size coding

NO. it's kinda old fashion plot and drawto from custom character set. The way i use to do it back in 1983,old habit. But it works. hehe. 

 

It, jumps back and forth between Basic and assembly. for everytime a new screen is drawn. But This is my last Game with basic code in it. Will use Assembly only code for new projects.

Okay, thanks! Jumping back and forth between TB and assembly is no easy feat to convert to 100% assembly

 

So, size coding it is then

 

But first some sports on the seeing-far!

Ok Thank you..See private message
