Pianoteq 8

Cut from product text:

"What makes Pianoteq superior to other virtual instruments is that the instruments are physically modelled and thus can simulate the playability and complex behaviour of real acoustic instruments. Because there are no samples, the file size is just a tiny fraction of that required by other virtual instruments, making Pianoteq perfect for any laptop.

Version 8 of Pianoteq brings numerous refinements in its engine and physical model, as well as newly developed Classical Guitar model."

Developers of high leveled sound software mostly try to catch the dynamics from a real acoustic instrument.
As we developed the Computergrand for the famous Viennese concert grand company we gained an incomparable treasure of experience and data in this case.

That is why our controller is often used as a reference keyboard.
The recomended software works perfectly with our MK's.  You don't have to load or tweak  some dynamic curves or similar to have an authentic feeling.

If you wish to adjust the dynamics (“weight of keys”) on the MK23 in anyway, you can do it with one knob during playing
without loss of the full MIDI range.
