Good:
-More inputs than SSL2/SSL2+
-Some professional mixing options
-SSL 360 software and direct routing
Bad:
-WME driver is no longer mono for channels, therefore WME audio driver applications (like ShadowPlay) capture both CH1 and CH2 in a L/R configuration. This will result in CH1 playing in L-channel, and it is not possible to make it non-stereo.
-Sometimes when powered on, outputs may be unresponsive or play white noise. This will likely be fixed at later date with a firmware update.
