SMx Audio System Software, Version 1.0 is the "old" version. This version ONLY works for 16 channel SMx systems delivered prior to May 2002. The newer builds, Version 2.0 and greater, work on ANY size SMx system from June 2002 on.
Also, note that the old and new SMx drivers are NOT compatible with each other. Further, the I/O devices used on those SMx systems ARE NOT directly portable.
