Software version 4.2 (Macintosh) is obsolete and no longer supported.

Spectral Engine I software (Macintosh) was frozen at v3.0. It is supported but no longer updated. It differs only in minor ways from v3.0b5. The Spectral Engine I software was originally integrated into versions 3.1 and 4.0 of our SEII software; customers who downloaded those versions can actually use it with the old Spectral Engine. However, the complexity of that integration introduced a number of (nasty) bugs, and so we canned the idea. If you are using v3.1 or v4.0 or any other version with the SEI, we suggest you immediately upgrade (or downgrade, as the case may be) to v3.0.
