Spend some time checking out features you have passed over...learn what benefits your keyboard may have ...unknown to you..

Like most keyboard people , we never explore the full capabilities we have....(I am not in that group )

Also take advantage of what you already own... Mixcraft has a great selection of VST's... Learn how to use them within Mixcraft...You have VST's that will do anything the workstations do.. You also have VST with the pads you are interested in.. You have a couple of great samplers...
