UnitedPlugins has released an update for SubBass Doctor 808, saying:
Although SubBass Doctor 808 has been released quite recently, SounDevice Digital listened to the customers' wishes and made a quick update.
The possibility to switch off the lowpass processing has been added. It opens possibilities to use SubBass Doctor 808 even on your mix-bus or instruments that require sub-bass treatment but still to have to pronounce high frequencies.
By default, the switch is on (as it was set internally before).
SubBass Doctor 808 is a plugin that treats the unheard sub-bass frequencies that can be harmful to some systems. That is especially useful when mixing while travelling or when using systems that do not deliver sub-bass frequencies precisely. A 15-days fully working trial version is available.
