I got the same response from
Soundtaxi tech support.
My computer is 2.4GHZ, 1.2G of RAM.....running NO OTHER APPLICATIONS....and I get the same skipping! I have soundtaxi PRO, too! I am a PAYING CUSTOMER!
Soundtaxi SUCKS!
It has RUINED hundreds upon hundreds of audio tracks!
DO NOT DOWNLOAD or PAY FOR Soundtaxi!!!!
To top it off - it never ever did convert 16 tracks simultaneously (as advertised)
