Working on sound blending using pulse width modulation. In the beginpost you can find a link to a work in progress version of the kirby's dreamland song. It's not recorded from the calculator.

Next step: Blending sound. The Idea is that the notes blend even if they're 3 "steps long" and another note from the other channel that is just one step long comes in the second step.

Like this:
|1  ||2  ||3  |

     [A-3]
[C-2__________]

|1  ||2  ||3  |


How do I tackle this problem?

I made a white noise generator too with pretty awesome results:
Code: [Select]
While 1
  rand^4->Port
  r1
  While 1
  End!If -1
End!If r2-1->r2

Experimenting with pulse width modulation. It seems that axe is not powerfull enough to produce a sine, but customduty cycles are possible. I made a vid. See video 03 in the startpost

Lolthatsstupid :) Changed it:
Code: [Select]
Lbl WAVE
.Gbd1WV is the wavetable that consists of 1's and 0's
.r1 is the delay between
.r2 is the amount of waves
for(C,0,r2
  for(B,0,31
    {Gbd1WV+B}->port
    r1->A
    while 1
      A-1->A
    end!if A
  end
end
Will this work?

Is this okay?
Code: [Select]
Lbl WAVE
.Gbd1WV is the wavetable that consists of 1's and 0's
.r1 is the delay between
.r2 is the amount of waves
for(C,0,r2
  for(B,0,31
    {Gbd1WV+B}->port
    while 1
      A+1->A
    endif A=r1
  end
end

I want to generate custom waveforms from a wavetable so I want to know how exactly can you controll the frequency acurately since pause gives me very low frequencies.
This is the wavetable of a saw for instance:

 _    _    __   __  ____

_ ____ ____  ___  __   

I really don't know if this is going to work :P

Please vote in the poll. I can add some features that are required to play the song such as virato and portamento.
Edit: I used famitracker to write the music in. Now I have to convert it by hand. I have to add some more wavelengths to the table for the bass.

Sow this is a long note:
Code: [Select]
freq({n+Gbd2},6000
pause 20*S-C

And this is a short note:
Code: [Select]
freq({n+Gbd2},3000
pause 20*S-C+450
1900/128,000=0.15
3000/0.15=450

or even better:

long note:
Code: [Select]
freq({n+Gbd2},S*20-C*15+6000
short note:
Code: [Select]
freq({n+Gbd2},3000
pause 20*S-C+450

Well I don't know. I am going to ask for help for the I/O interface communication on the TI-nterface (interface in an interface XD)

Nope those are too fast :P Do you know any slower mm songs?

Added a poll. Please vote!

I want to add some more notes to the wavelength table so that you can make interesting compostions. I have a very simple song that I made earlier for a prototype of Mono Tune. It's fully compatible because I used the same wavelength table. I will record some of it and put it on youtube.

The arpeggio blending works now and there are 2 squares. I have to optimize some code before I release the first pre-alpha
I am designing a tracker right now. Maybe I will make some sort of Cubase/fruityloops design for the pattern editor.

(Rate my posts if you think this project is helpfull. Then I will consider to make a tracker)
