The Pro 53 VST was designed to emulate as accurately as possible the Prophet Synth, so consequently it did not go beyond this, and has now of course been discontinued.

The best substitute is probably Arturia (Although there are others if you do a Google search) however you will have to email them to see if it offers the additional features you require.

Hope this helps
