An Axe piano with 5 octaves
« on: April 28, 2011, 04:12:13 pm »
Hello,

I less than 1 hour, I made a piano in Axe, which can play sound on five octaves.
(Axe sound in Hertz : Freq(32768/Hz, TIME) )
I add a picture, a mix of 8 white keys, 5 blacks, and a hole at the end of each key :
When we press a key, I make sound, and a X ( for blacks ) or a little donut ( whites ) go out of the key  :hyper:

You need to take your calc with the screen on your left, and the port on your right.
To play a note, press the key as it were a real piano : the [2nd] to [->] keys are the 8 whites, and to play black keys, its the key just over the white :
C note is [2nd], C# is [mode], D is [alpha], D# is [xtOn], etc.
with [▲] or [apps] you can go down of an octave, and go up with [▼] or [1].

I'll put codes soon, and a gif in 2 weeks ( no wabbitemu here, in vacations ...  :'()

oooh nice.
Does it support multiple notes?
I tried to do it one time, and I managed to make it produce 2 notes at a same time, but it barely works so XP

?!.
How can you make two sounds with axe ?
If two notes are pressed, only the higher is played.

Just a bug : the sound quality is ...  :banghead: (like this ^^)
I tried interrupts, but can you explain me how it works ? After many seconds I've no more sound...  :(

This is great! I was thinking about making a guitar program at some point. :P I'll have to find a way to defy reality and play 6 notes at once though xD

If two notes are pressed, only the higher is played.

One way is to alternate back and forth between the two frequencies very quickly.

Maybe you have to detect both keys and then play one after the other real fast? Is there a way to really "mix" sounds?

well, as i said, it barely works.
This is what I did:

for(A, 0, 100
freq(314,400
pause 10
freq(284,400
pause 10
End

Doesnt work on most of it(it sounds wierd) but it works.

EDIT: oh btw, i tried when i was porting music
EDIT2: ninja'd, ninja'd. pity me.

Technically, when you're hearing multiple notes it's really just a combination of the frequencies. But that's just simple physics of adding and subtracting waves.

supporting "real" multiple notes is what I really want in Axe.
