K2vxÕs sound engine, and, if the K2vxÕs LocalKbdCh parameter matches my controllerÕs
transmit channel, to the K2vxÕs MIDI Out port.Ó
If you change the value of the ModWhl parameter, the Mod Wheel will no longer send the
MWheel message, and any control source parameter with MWheel assigned as its value will no
longer respond to movement of the Mod Wheel. All of the control assignment parameters on
the MIDI mode XMIT page (and in the Setup Editor) can be programmed to send any of the
MIDI controller numbers. For example, if you assign Foot (MIDI 04) as the value for the Press
parameter , then generating mono pressure messages from your MIDI controller will send a
Foot (MIDI 04) message to the K2vxÕs sound engine, and will affect any control source
parameter that has Foot assigned as its value. If the value for the K2vxÕs LocalKbdCh
parameter matches your MIDI controllerÕs transmit channel, then in this case the Foot message
will be sent to the K2vxÕs MIDI Out port as well, when you generate mono pressure messages
from your MIDI controller.
The other type of control source is independent of the movement of physical controls. These
control sources generate their control signals internally, and might be called software control
sources. They either run automatically (like A Clock and RandV1), or theyÕre programmed to
generate their signals according to parameters of their own (as with the LFOs and FUNs). The
software control sources must have some non-zero value set for one or more of their parameters
before theyÕll generate control signals.
To summarize, there are two different cases in which youÕll assign control sources. One, the
transmit case, determines what control message will be sent by a particular physical control.
For example, MWheel is set by default to be transmitted by the Mod Wheel. The other case, the
receive case, determines which control message will activate a particular control source
parameter. For example, if you assign MPress as the value for the Src1 parameter on the PITCH
page in the Program Editor, then that layerÕs pitch will be affected whenever an MPress
message is generated by any physical control.
Control Source Lists
ThereÕs one long list of control sources stored in the K2vxÕs memory, although not all control
sources are available for all control source parameters. With time youÕll become familiar with
the types of control sources available for various control source parameters.
The available list of control sources varies depending on the type of control source parameter
youÕre programming. There are four basic types: MIDI control sources, local control sources,
global control sources, and FUNs.
When youÕre setting the control assignment parameters on the MIDI mode XMIT page or in the
Setup Editor, youÕll see only the portion of the Control Source list that has values appropriate to
MIDI controller messages. Consequently we refer to this subset of the Main Control Source list
as the MIDI Control Source list.
YouÕll see variations on the Main Control Source list as you program the other control source
parameters. WeÕll explain these variations, but itÕs not important that you memorize each
variation. The lists differ to prevent you from assigning a control source where it would be
ineffective. All you have to do is to scroll through the list of control sources available for any
given control source parameter, and choose from the available values.
If youÕre programming one of the FUNs, youÕll see the Main Control Source list, which includes
almost every control source from the MIDI Control Source list (with the exception of Data Inc,
Data Dec, and Panic, which belong exclusively to the MIDI Control Source list). The list for the
FUNs also includes a set of constant values, that set an unvarying control signal level for one or
both of the FUNÕs inputs.
For most other control source parameters, youÕll see the Main Control Source list (without the
FUN constants and the three special MIDI control sources we mentioned above). There are two
