The Control Editor
This editor allows you to assign MIDI control sources to K150X control destinations. Just as MIDI has two types of control
sources (continuous controllers and switches), the K150X has two types of control destinations: virtual controls and virtual
switches. Virtual controls recognize the full range of MIDI data values (0 thru 127) while virtual.switches only respond to 0
(OFF) and 127 (ON). There is, however, no restriction on assigning MIDI switches to virtual controls, or MIDI controllers to
virtual switches.
Virtual controls are either unidirectional (0 is minimum, 127 is maximum) or bidirectional (with 64 as the center point). The
direction of the value, as indicated by the arrow symbol in the K150X display, can be reversed by pressing the - key. For
example, a control which sends higher MIDI values when turned clockwise can be reversed, having its signal interpreted as
being lower MIDI values when turned clockwise. The pitch bender is an example of a bidirectional control.
When a continuous controller is assigned to a virtual switch, the switch will only react to the extremes of the controller range
(OFF and ON); any intermediate values are ignored. In the opposite case, the virtual switch will only see two values (0 and
127) which correspond to the minimum and maximum range of the controller.
Note that the pitch wheel and monophonic channel pressure are treated as extra continuous controllers; they can be assigned
to any control or switch destination. Polyphonic key pressure is distributed directly to individual notes and can be used to
scale a number of sound layer parameters. For controllers that do not generate polyphonic pressure, a virtual control is
provided which allows any control source to act like polyphonic key pressure.
The K150X also provides a connection for two external switch pedals. These pedals are treated as extra switch controllers
and can be assigned to any control or switch destination.
F1, F2, and F3 in the Control Editor
Pressing F1 returns you to the top of the list.
Pressing F2 jumps to the first of the Chorus control assignments.
Pressing F3 jumps to the first of the Vibrato control assignments.
