Dynamic KeyboardMass feature
Keyboard mass controls in the Kispest virtual pipe organ
The Dynamic KeyboardMass™ (KM) feature is implementing a unique functionality in selected
Hauptwerk sample sets simulating the temporal behavior of a pipe organ's keyboard and tracker action dynamically. It was engineered by Csaba Huszty from Inspired Acoustics to be first implemented in the Kispest Pipe Organ Samples by Reiner Suikat in November 2009. The feature simulates keyboard and tracker action mass and inertia by various time-domain parameters that
change dynamically according how the keys by the organist is pressed.
Here is an analogy of the temporal (i.e., time dependent) behavior in a pipe organ's keyboard and tracker action: It has been said that electropneumatic actions are delayed in time, but the palletes open quickly (under the strong action of electromagnetism), once the electropneumatic circuits make contact. Conversely, tracker actions begin to speak essentially instantaneously in time, but heavy tracker actions have more inertia and thus require more time for the palettes to open completely, allowing wind to enter the pipes.
Keyboard mass controls in the Matyas virtual pipe organ
The Dynamic KeyboardMass™ allows simulation and real-time control of the organ's keyboard heaviness, independently for each keyboard. This feature is claimed to add a new layer of realism to play the virtual pipe organ.
A demonstration of the KM model
The model in the Dynamic KeyboardMass™ sets the response of both the speaking and the release part of the pipe sound simultaneously and dynamically, adopting itself to your actual key-presses. Practically this ensures that the virtual instrument remains very responsive even if very heavy keyboards are set.
The Dynamic KeyboardMass™ feature which changes the dynamics temporally complements the tracker action noises that respond to touch-sensitivity in various Inspired Acoustics sample sets.
