As you may have already know Native Instruments discontinued few of its instruments including PRO-53. Do not panic, it’s good to know that Native Instruments still provides support for the actual owners of PRO-53.
As this is clear we want you know that Kreativ Sounds will also support PRO-53 by constantly improving and providing new sounds to ABYSS PRO-53 V1 and ABYSS PRO-53 V2.
In fact we are already working on free updates for these two products because we love the prophet sound … the legend lives on
