Vintage Clav click and excite in Logic Pro for iPad
The Release Click and Excite Detail parameters determine the string excitation, emulating the characteristics and power of the hammers striking the string and other elements that form part of the initial key strike.
Also emulated are string excitations that occur on key release. To explain, the rubber hammers of the original D6 age and decay, just like piano hammer felts. Worn out D6 units produce a distinctive “click” when a key is released. This is due to the string sticking to the rubber hammer before being released. The characteristics of this release click are part of each model and can be precisely adjusted.

Release Click parameters
Intensity knob and field: Set the level of the release click. A negative value of −1.00 eliminates the release click. To simulate an old D6, increase the value.
Velocity knob and field: Set the velocity sensitivity for the key click sound. The maximum key click level is set with the Intensity slider and the velocity mode is determined with the Velocity mode switch.
Random knob and field: Control the amount of release click level variance across the keyboard. This slider simulates the wearing of some hammers, but not others, emulating the “wear and tear” of a D6. The farther to the right the slider is moved, the greater the variation between release clicks on some keys. At the leftmost position, all keys have an identical release click level.
Velocity Mode buttons: Turn attack (Key On) or release (Key Off) velocity on or off. Turn on the Automa(tic) button to automatically detect incoming release velocity values. Received release velocity data is used to shape the sound. If no release velocity data is detected, it acts as if it is turned off.
Excite Detail parameter
Shape knob and field: Contour the attack shape, simulating the hardness of the rubber hammers in a D6. As the instrument ages, hammers wear and split, changing brightness and tone. Negative values—to the left—provide a softer attack, and positive values result in a harder attack.
