I have this thing
http://www.behringer.com/assets/UCA200-GY_P0496_M_EN.pdfIt is 16bits and 44.1/48kHz capable, I think.
Maybe it can work with Ploytec OS9 drivers. There was one user here that had them, right?
It says it work since mac os 9.0.4 on G3s
The UCA200 is PC and Mac-compatible. Therefore, no installation procedure or drivers
are required for the correct functioning of the UCA200.
To work with the UCA200, your computer must fulfill the following minimum requirements:
MAC
G3, 300 MHz or higher
minimum 128 MB RAM
USB 1.1 interface
OS 9.0.4 or higher, 10.X or high, but it has no drivers to download, so I guess is "generic" to OS 9, In windows is "usb codec".
I would like to use it with Protools Free, but I also like Digital Performer and Logic. Cubase also, but not my first choice always.
