Conversion midi>mp3 (wav) and transposition of mid

Conversion midi>mp3 (wav) and transposition of midi files

Hi!
I want:
1. To transpose (is the spelling correct?) midi music (phonograms)
2. To convert midi to mp3 (wav) preserving (introducing) the best possible quality...
Thanks

Jan answered 2, so I'll answer 1.

If you mean transcription (taking a MIDI file and generating sheet music), this is a rather difficult problem that includes rhythm quantization as its main component.  For mechanical recordings it's fairly easy (you just say "quarter note = 150ms, half note = 300ms" or something), but it fails horribly on actual human-played recordings.  I'm getting paid as a rsearch intern over the summer to come up with a decent system for doing that (intented for realtime use, but can probably be applied to MIDI-file transcription as well).

If you actually meant transpose (take the music and move it to another key), this should be a bit easier, but I'm not aware of any software that does it.  It's not a completely trivial problem, but should be doable if it's normal western music in a well-defined key, and you specify both the from and to keys.

Well, Delirium, actually I want to transpose (to adjust the phonogram to the voice of the singer). If I am not mistaken, Cakewalk SONAR XL v2.0 allows to do this. But how to do it automatically with the help of it ? (I.e. to adjust the pitch of tone... take the music and move it to another key, as you put it, suppose it is even more correct to say so) Or, maybу another software? Special utility?

And about the conversion... I want to emulate Yamaha 2000 or some other good sequencer while making a wav (or mp3) out of MIDI. The quality of the conversion (of the resulting wav (mp3)) is of paramount importance!
The alternatives:
1. Total Recorder
2. RTFM
3. WinGroove
4.

WHQL-certified Yamaha SoftSynth on Microsoft's Corporate WinXP Update site. It just installs like any other driver through the "Add New Hardware" wizard. No word on whether or not it expires, if ever (probably not). It has 4MB sample set, and a reg hack is needed to set polyphony from 32 to 128.
  ???????? The links?
5. Cakewalk SONAR XL v2.0 ?
6. Syntrillium Cool Edit Pro v2.0  ?????????
7. Sound Forge 6.0  ??????
8. Audio Compositor (SometimesWarrior says this one is extremely good)

I don't care if the software is free or paid. Quality is important, that's all.

Audio Compositor is the only one i would use. Coupled with a high quality SoundFont bank, for free, such as one from here, it sounds great to my ears. I would recommend the 84mb bank, in fact. It sounds better to me.

Audio Compositor requires registration, however. But, for SoundFont rendering quality, i have found audio compositor to be unbeaten. It takes a very long time, but will render up to 24/96, with options for anti aliasing kernal size, manual output level adjustment, packed floats / integers, dithering, etc.

If your feeling particularly brave, you can load the SF bank into an SB live too.

Here is a sample of Audio Compositor rendering a midi with the aforementioned bank (084.0mg ALL In ONE GM V1.1 Bank)

Thanks, DarkAngel! Audio Compositor  seems to be very good. I'll take it. What is the current version?
But one thing left. Namely - transposing. Still don't have any idea how to do it.

Thanks, the current version is 4.5, available from http://home.att.net/~audiocompositor/

Registration is $40, which is very reasonable considering its output. As for transposing your output, im not sure exactly how you can do it. However, im sure there must be a program to transpose waves by a certain amount.

The question about transposing is solved.
(SONAR 2 > MIDI Effects > transpose )
I am very glad

BTW, AFAIK  the sound card while converting is not used at all? (I mean Audio Compositor + Soundfont)? I heard about the soundfonts, that they are used only with Sound Blaster Live! Is this correct? I.e. I cannot use Audio Compositor + good Soundfont with my  audiocard? (not SB Live?) 
What is the best soundfont? Is there a sound font, the clone (or very much alike) of Yamaha 2000?

And one more thing: most of my MIDIs are not GM, but XG (Yamaha's). What soundfont is the best then?

Audio Compositor does not use the soundcard, it renders the soundfonts in software, which give you much more control over exactly how they are rendered.

You can load the soundfound banks into the SB Live or above, and play back the track using any midi player, and sample the audio in, however this will not be as good quality as using audio compositor. Also, i am doubful the live would cope with very large soundfonts.

If you wish to buy a *really* high quality soundfont, companies such as Sonic Implants will be able to help.

And what about free ones?

from TheSoundSite.net

The largest ones are at the bottom of the page. As a general rule, they have the best quality. The 84mb All in One bank sounds best to my ears, but choose whicehever one sounds best to you.

Strange things happen... From my MIDI after conversion disappeared bas, from some piano (i.e. became very-very quiet). What should I do?
And about the transposing, SONAR 2 spoils drums!

My reply is from the future. Audio converters have gotten much more functionality during the past 6 years. For example, if you take LINK REMOVED, it allows converting midis with the help of soundfonts. Which means that you can select instruments for your tune. And there are many soundfonts: for example, visit personalcopy.com, homemusician.net. Conversion speed to mp3 (wav) depends on the complexity of the active soundfont, but usually a 5-minute midi is converted within a couple dozens of seconds.

From the future?? Or from the past?

Recording a midi to .wav has been possible since the days of timidity++ and that is an old software.

All soundfonts are different and often have different volumes. Sometimes a certain range of an instrument is missing (due to limitations to soundfont format and/or laziness of creator).

Don't transpose the drums (channel 10). If you want to change the pitch of the drum channel you have to do a pitchbend.
