The reason is simple: since I don’t own Cubase or Nuendo (I’m a Logic user…) I used a demo version to test the protocol handling.
Last check was in June 2003!
I don’t really know if it is still working with current versions, especially because Steinberg added some SW workarounds into Cubase in order to overcome imperfections of the original hardware.
my cubase le version is from february 2006. i didn´t have the time to do a complete checkup and i didn´t connect motorfaders yet, but so far the houston emulation seems to work just fine. the tracks and parameters are displayed correctly and the buttons (at least those i tested) are doing what they are supposed to.
but i wanted to be sure, that i won´t get into any trouble if i go any further.
