I have a question regarding Acid Pro, i read it can:

"ACID PRO allows you to preview any loop before adding it to your mix, automatically matching the tempo and key in real time."

i am especially interested in the key adjustment feature. can anyone provide insight into this? would i set a key for the project and everything i add is adjusted or what?

please somebody shed some light on this issue

thanks

ACID-ized WAV files have a root note and a tempo stored within them (I think they use some spare bits in the WAV format). ACID looks at that information and uses it to adjust the loop to the key and temp of your project. So, a loop whose root note was C, and that arpegiated a Cmaj chord, when pulled into a project in the key of G, would arpegiate a Gmaj chord instead.

There are provisions in ACID to set the loop properties of a WAV file that doesn't have any stored in it. You can also do this in SoundForge, and maybe other audio editors (don't know for sure).

thanks for the info!

i know that for example fruity loops can save in acidized format. i am unsure wether i adds key information then as well.

any way to (auto-)acidize loops that haven't got any acid info in them?

How is that doen onthe loops of many sample-cds?

Can it be done in, as mentioned, Soundforge for example?

ACID has a feature called the BeatMapper than can help you figure out tempos and add that info to a WAV. For the root pitch, I think you're on your own, but I'm not sure; ACID will let you add it to the WAV but I don't think it does anything to figure it out. Could be a tough audio processing problem on some complex loop or a rich pad sound, f'r instance.

I've only ACID-ized drum loops where all I cared about was tempo, and haven't bought any sample CDs, just one of ACID loops from Sony's line. You'd have to look at the features of audio editors and FL to see if they can help you out. Otherwise, I guess you can consider it ear training.

Hope this helps.

Acid automaticly sets the tempo for a non-acidized loop. It does not set the key. You have to do that manually. And the auto- tempo doesn't always work well. For example, mp3 loops don't always loop well, because they have a little dead space at the beginning of the file.

thanks again!

i have found out there are two programms, that can batch-acidize entire folders.
they are: acidizer and chicken sys translator. afaik they will not detect the key/tempo but the info you give regarding tempo and key will be applied to entire folders. does anybody know if i am right?

if i am not mistaken, there is no way of auto-batch processing loads of loops in one go with detection of both key and tempo. or am i wrong?

i am a little lazy, you know. but if it has to be done i will do it the hard way

again, my thanks go out to all the contributers!!

There is another free program called AcidHead which will put the tempo/key in batch into all the loops in a folder. Search for it in google. The site from where I downloaded went down long back. Acidizers also does the same thing. No idea about Chicken Sys Translator.
You can set the tempo/key for a WAV file in Acid Pro in a non-destructive mode. Just add the loop to the project then right click on the track and select properties. In the new pop-up window you will have options to set the tempo and key. There are many methods to apply for detection of the beats. Try it out. You can render the loop which will also add the tempo/key you just set. Hope it helps.

i found acidhead if anybody needs it.

so, i get there's is no way of having a folder both auto-detected (key+tempo) and the acidized? just want to settle this before i start working

One of the "problems" with acidized files is that the markers, many times, need to be adjusted by hand. This would be done after the file is "acidized." And I think you can only do that in Acid, in the loop's properties. If you don't do this, the loop's abilitly to be adjusted over a wide tempo range is limited.
