Hi Diki
Both the Wersi OAS arranger (Over 10 years old and the most basic (Primitive) arranger on the planet) and the Wersi OAA (One of the more advanced arranger sections on the market) send this information, (Manually selectable for when using converted styles or Midi to style conversions) and they work on both Akai samples and VSTi with no problems. (Closed arrangers may or may not have these options user selectable as all new voices are provided by the manufacture, whereas Open keyboards or software have no option but to include them, as there is no way the manufacture can know what the user is going to use)
Note: Wersi calls these options Pad Mode in OAS, and they come under Edit Pattern in the OAA
