Okay..

I tried this and heres what i got.

1. Acidized two 127 bpm loops. Using Soundforge. Trimmed them. Set them as a sustaining loop.

2. opened them up in acid pro 4.0 and the tempo's were WAY WAY WAY off.
I must say they were like 170 when you play them but showed as 120bpm.

I'm not really sure whats wrong there.

lol! You don't know how to acidize loops properly. Try harder.
see, in music there's such a thing Beats and measures. Now go do your homework and figure it out. I pointed you in the right direction.

Since some of us aren't here to laugh at others, let me actually try to help you out...

Defining the type of loop is only part of the acidizing process. You also need to set the "Acid Properties." Make sure your number of beats and key info are correct, and you should be fine.

BTW -- Ammeris, you have some broken links on your homepage...

Time and tempo are related.

Let's say you want to create a typical common time, four beat sample in Sound Forge that you want to use in ACID. Let's say you also want this sample to fit within a specific tempo of 120 BPM.

To create such a Loop, the sample would have to be exactly 2 seconds long.

The formula to figure out the length (in time):

240 / (intended tempo) = (length in seconds)

(There are other formulas for other time signatures as well, but this one's used for common time.)

So, for our example:

240 / 120 = 2 seconds

Once you create your sample, you must complete the process by ACIDizing by using Special>Edit ACID Properties on Sound Forge's menu bar.

Since you already know you want this 2 second sample to be 4 beats long, you'd enter that under "Loop." Your Loop will then be ACIDized at 120 BPM.

Also, take note that ACID's overall project tempo is taken into account after it knows the original tempo of the ACIDized Loop. So if your original Loop is 120 BPM and your overall ACID project's tempo is 140 BPM, the Loop itself will be stretched to match the overall project tempo 140 BPM.

Sound Forge also has a Tempo gauge located under its ACID Loop Creation Tools toolbar that helps gauge a particular selection's tempo, which can come in handy should you not feel like doing the math. :)

The tool for setting up the way ACID stretches loops is far better in ACID itself than in SF.

Right click on the grey area by the volume fader for the loop and select Properties. Now look under the Stretch tab. Here you can set the number of beats, the stretching method and how ACID splits the sample up for stretching. Once you've tweaked it to how you like it, you can save the metadata in with the wav file, so ACID will know how to use it in future, or just save the ACID project and these properties will be set for the sample in the project, but not stored as metadata in the original wav.

If your loop is playing at its original tempo in your project, you'll get best sound quality by pitch shifting segments (particularly for bass), however, this will mean you can't pitch individual events about.

Have a play. You'll find that this can be used to create some really interesting effects and huge sound quality improvements and should be considered whenever a new sample is added to a project.

Thanks for the info. What you said actually was the missing piece of the puzzle that I needed. Thank YOU for helping me out.

Yep, That is exactly what I needed to do. Done it. I was not defining the number of beats. Thanks for the time that you spent on the instructions.

Ok, Ok, I am learning. Thanks for the info. I want to take individual tracks that I have created and using in other songs, to make entirely different songs. Kind of like my own Acid sample library. This info will help. Then again that is one of the things this application is for.

I forgot to mention, like BFB noted, that ACID, by all accounts, should be your last stop in ACIDizing your custom samples. You will almost always want to access the stretching properties and do any modifications there.

(Note that ACID Pro is the only version of ACID that has the ability to work with stretching properties.)

You can definitely use Sound Forge as noted before, but think of it as a stepping stone to the final product.
