Source: A provider of MIDI events that can be
directed to the WK4 Tracks. In the WK4, the
sources of MIDI events are; the keyboard (lo-

Disk environment, the Source refers to the data
storage device which contains File to select

respect to a standard value.
Tweak: A term that describes the slight modi-

example, using the programmable pedals to
which the Edit Sound parameters have been
assigned (Filter, Attack, Release, etc.).
User Interface: All that which appears within
the Display. The means with which the user
communicates with the musical instrument -

parameters in graphical and text form.
User: Generally, this term indicates all that
can be programmed by the operator.
Velocity: MIDI message always coupled to the
activation of a note. Velocity controls the sound’s
intensity, proportionally to the velocity with which
the keys are struck. Velocity is also used to
control various parameters in Edit Sound.
