Are you aware these are not velocity sensitive?
I'm still relatively new to this endeavor, and I don't get enough time to sit around and exploit all of the complexities that Hauptwerk has to offer, so please explain the benefit of "velocity sensitive."
Velocity sensitivity is the change in note volume that is dependent on how hard/fast the key is struck. In a non-velocity keyboard there is only one switch per key, in a velocity sensitive keyboard there are two. The MIDI standard defines a note on event as a both a MIDI Note number value (0-127) and a velocity value (0-127).
The velocity value is calculated by the encoder from the length of time it takes the second switch of each note pair to activate.
In a piano sample this is very important because the loudness of the instrument is controlled by how the strings are hit by the hammers which are launched by how the keys are struck.
In an organ sample set maybe not so much or not at all. Most sample sets of electric-valve controlled wind pipes how fast the valve opens is a constant. The exception being a 'tracker touch' organ which could have the valve opened slowly by a slow depression of the key. This is because the valve and the key are mechanically joined by the tracker mechanism.
If you will never have a piano as one of the ranks in your VPO there is no reason to have a velocity sensitive keyboard. But if you were to add a piano synthesizer module to the Hauptwerk VPO or have a tracker sample set that is velocity sensitive, it would need a velocity sensitive keyboard to respond properly.
Hope that helps.
