Does anyone know of any software that I can download to convert MP3 music into midi sequences?

LOL @ cubaxd...

To seriously answer your question, its not possible to convert a streamed format to a source format. In fact, you can only convert a streamed format to another streamed format.

Modules and midi are source formats.

There is software available that can tone-recognise a wav file and output a midi from it, but it works poorly. You must have a single tone wave file and the only thing you'll get are the notes used, not the sound itself. Even worse, if that wav has a vibrato in it or a very difficult waveform, it will recognise it as several tones at once and your output is screwed.

Due to all the complications it has, I say: its not possible.

So what are the "any" keys again? Maybe I need a keyboard upgrade. I have on my keyboard the following keys:

1. An escape key
2 - 13. 12 Function keys (labeled F1 - F12)
14. A print screen/system requests key
15. A scroll lock key
16. A pause/break key
17. A grave (not accute) accent/tilde key
18 - 27. 10 number keys (labeled 1 - 0)
28. A hyphen/minus/underscore key
29. An equals/plus key
30. A backspace key
31. An insert key
32. A home key
33. A page up key
34. A num lock key
35. A num forward slash key
36. A num asterisk key
37. A num hyphen/minus key
38. A tab key
39 - 48. 10 letter keys (Q - P)
49. A left bracket/brace key
50. A right bracket/brace key
51. A backslash/vertical line key
52. A delete key
53. An end key
54. A page down key
55 - 59. 3 number keys for the num pad (labeled 7, 8 and 9)
60. A num plus key
61. A caps lock key
62 - 70. 9 letter keys (labled A - L)
71. A semicolon/colon key
72. A single/double quote key
73. An enter key
74 - 76. 3 number keys for the num pad (labeled 4, 5 and 6)
77. A left shift key
78 - 84. 7 letter keys (labeled Z - M)
85. A comma/less-than key
86. A period/greater-than key
87. A forward slash/question mark key
88. A right shift key
89. An up arrow key
90 - 92. 3 number keys for the num pad (labeled 1, 2 and 3)
93. A num enter key
94. A left control key
95. A left start key
96. A left alt key
97. A space bar
98. A right alt key
99. A right start key
100. A right click key
101. A right control key
102 - 104. 3 arrow keys (labeled left, down and right)
105. A number key for the num pad (labeled 0)
106. A period key for the num pad
And there's my keyboard a simple set of 106 keys. I do not have any "any" keys.

And to correct LPChip, it is possible to convert MP3s to midi sequences, but the software http://www.widisoft.com/english/download.html that I found to do that is very expensive ($99 and some change). The demo only converts the first ten seconds of the song.

Actually, that ain't true. NOt entirely, anyway. IN the same way a tuner can detect a pitch, software can detect pitches from songs and convert them to MIDI. I only knew of 1 such piece of software (trialware, unfortunately), but it did work, and fairly accurately. It COULD hand polyphonic songs, but the problem with that was that every instrument had to have a standard MIDI 'equivalent', and of course we all know that MIDI instruments sound nothing like the instruments they're supposed to be.

RWP, I'll keep an eye out for ya.

EDIT: Damn I'm ignorant. I didn't even notice the software link that RWP pointed out. But it's not the same as the one I had previously used.

Sorry, Really Weird Person.

I thought, a thumb question needs a thumb answer. But there are really such tools.

I made a test with a song by the austrian-american-swiss... cabaret artist Georg Kreisler, which i covered (http://www.oocities.com/cubaxd/ich_kann_tanzen.it) (plagiarized :wink:) two years ago.
The original song (flash) can be found here (http://www.kidlane.de/georg-kreisler/hits.html) (i dont want to link to the file directly without permission, so search for "ich kann tanzen" or so).
And the converted midi file (http://www.oocities.com/cubaxd/ich_kann_tanzen.mid), which was converted from a high quality version of that song, whithout changing any settings. And i was astonished, how much the program did gecognize.
But i wouldn't take it as a ringtone. :)

Don't give up. ;) But sorry again. That was really new to me.

So, SoundCrafter, do you remember the name of the software that you used? I would like to see it (and maybe try it out, herpaps (perhaps)). Unfortunately, I do not see a name for or link to the software.
