Dynamic KeyboardMass™ simulation and control


Keyboards and tracker actions of pipe organ have mass, inertia, which describe their response while you play. The Dynamic KeyboardMass™ is a special feature in the PAB Gravissimo Edition that allows you simulate and control each of the organ's keyboards’ and pedal board’s heaviness independently with the attached slider, even if your keyboard controller does not support any dynamics at all. This revolutionary feature adds a new layer of realism to play the virtual pipe organ. The Dynamic KeyboardMass™ model sets the response of both the speaking and the release part of the pipe sound simultaneously and dynamically. Practically, this makes the virtual organ a more living instrument and ensures that it remains very responsive even if you set it to have very heavy keyboards.
The controllers for the Dynamic KeyboardMass™ simulation can be found on the Performance Page. By moving the slider toward the setting ‘heavy’ the keyboard may feel more and more heavy. To completely turn off this feature, for compatibility, you can engage the K.mass off switch which will temporarily disable the functionality for the given division (regardless of the current keyboard assignment).
