WHAT IS “KEY CLICK?”
On a tone-wheel Hammond Organ, each time a key is depressed with an active Drawbar registration, a Key
Click (or Key Pop) is heard just before the note sounds. This is because, unlike other electrical or
electronic musical instruments, the sound is always present at the key contacts. Therefore, pressing a
playing key will likely intercept the sound wave at some point along its excursion, creating a “spike” or
attack transient. This transient is heard as “Key Click.” Since the generated sound is interrupted when a
key is both pressed and released, there is a Release Key Click as well as an Attack Key Click.
The ENVELOPE Parameters on your SKX PRO allow you to replicate this characteristic of vintage tone-
wheel organs. You can adjust the rate of Attack (when a key is depressed) and Release (when the key is
released). The data chart below shows the options you can select.
ATTACK & RELEASE ENVELOPE
Parameter Description
Con This is the envelope of the key-click(s) generated with the Virtual Multi-Contacts.
1 ~ 15 This is the rate of Attack without the Virtual Multi-Contacts. The greater the
value, the slower the Attack (the speed at the which the Drawbar registration
sounds when a key is depressed).
R1 ~ R15 This changes the Release rate. The Attack rate is that provided by the Virtual
Multi-Contacts. This means that the onset of the tone will be instantaneous while
the Release rate is regulated by the numerical setting.
AR1 ~ AR15 This Parameter disables the Virtual Multi-Contacts and allows you to change
both the Attack and Release rate. At higher numerical settings the Attack and
Release will be slow, similar to that of a pipe organ.
Turn the VALUE knob to make your selection.
NOTE: This Parameter is not available for the Pipe Organ Type.
