Ive been looking around for field recorders to sample with, someone recommended a recorder for $200, half of the standard field recorders, but it records at 20bit rate. I plan on importing these files into gigastudio which will be playing as a VST instrument in cubase SX. Will i enounter any problems from using a 20bitrate sample? i recall hearing something about all of the audio files and sounds must be the same bit rate as the entire project, and that the defualt project is at 24bit.

Is their any way to increase the bitrate to 24 after i get the sample on my computer?
 
First, what you mean is bit DEPTH not rate. It's sampling rates (44.1 kHz, 48 kHz, etc) that must match. 20 bit files will drop into most software recorders that can work at 24 bits no problem.
 
the palm studio is what im looking at. its at a 20bit, 31.25kHz sampling rate. will this create problems with cubase? i think my settings for cubase are at 48K. is their a way to increase sample rates? ive heard that it makes the sample sound really shitty if you increase the sampling rate.
 
Reads PCM WAV files of bit depths 8, 16, 24, 32 and 64

doesnt say anything about being able to read 20bit files.
 
I use Soundforge for sample rate conversion. I'd bet money that the program TimOBrien sugested will dither a 20 bit file just fine.
 
A good rule of thumb to follow when concerning bit depth is, you can load audio files that are at or below the bit depth set in the project. You shouldn't load audio files whose bit depth is above that of the project as truncation will occur, which is to be avoided.

As far as sample rate is concerned, most current soft-samplers will automatically convert them to the sample rate set in the project. However, if you're importing audio files directly into an audio track in your project, you'll need to convert the sample rate to the current project sample rate.

In Cubase when importing audio files into a track, you automatically get a dialog box asking if you want to change the bit depth and sample rate to the current project settings. You don't need to bother with the bit depth (as long as it's at or below that of the project) as it won't affect anything, but you will need to convert the sample rate.

One last thought. You mentioned that the Palm Studio records at 31.25kHz sampling rate. This is lower than the CD standard which is 44.1kHz. I really couldn't recommend this for any professional work.
