MidJay Pro, SD7, SD40 and SD9PRO is the same platform system..
And yes.. The SD9Pro converts the Audya (PAT) Styles to new type (KST) styles... The new type of KST Style, is much improved than problematic PAT (Audya type Styles)..
As we know, the Ketron Keyboards they use GM Soundboard and its very easy to convert correct a style.. The convert created only in Midi Sequence...
Therefore should to improve (after the convert of Audya PAT), the correct Audio Drums, User Audio Drums (only in SD9Pro), mix, FX or more things because every machine use different DSP, different GM Banks and more things...
Also the new SD9Pro is compatible with simple User Audio Drums of Audya (@) and we can to create and import new Audio Drums.
Also a very important thing in new Sd9Pro is to have User Midi Sequences in Modeling Smart Style Method of Ketron..
Very important!!...
