Program Mode and the Program Editor
Program Editor—LAYER Page
Pitch Bend Mode (PBMode)
This determines how Pitch bend control messages will affect the current layer. A value of "All"
bends all notes that are on when the Pitch bend message is generated. A value of "Key" bends
only those notes whose triggers are physically on when the Pitch bend message is generated
(notes held with the sustain pedal, for example, won't bend). This is great for playing guitar
solos on top of chords—play a chord, hold it with the Sustain pedal, then play your licks and
bend them all you want; the chord won't bend with it. A value of "Off" disables Pitch bend for
the current layer.
Trigger (Trig)
Set Trig to "Rvrs" to have notes triggered on key-up. The initial velocities of notes triggered this way
are determined by the release velocities of the keys that trigger them. The default setting is "Norm"
Delay Control (DlyCtl)
Here you select, from the Control Source list, a control source that will delay the start of all
notes in the current layer. The length of the delay is determined by the following two
parameters. You'll assign a continuous control like MWheel for the DlyCtl parameter when you
want to vary the delay time, and a switch control if you want the delay to either be its
minimum value (switch off), or its maximum (switch on). The delay control will affect only
those notes triggered after the delay control source is moved; the delay time is calculated at each
note start, based on the status of the delay control source at that time.
Minimum Delay (MinDly), Maximum Delay (MaxDly)
The length of the delay is determined by these two parameters. When the control source
assigned to DlyCtl is at its minimum, the delay will be equal to the value of MinDly. The delay
will be equal to the value of MaxDly when the control source is at its maximum. If DlyCtl is set
to OFF, you get the minimum delay. If it's set to ON, you get the maximum delay. This doesn't
change the note's attack time, just the time interval between the Note On message and the start
of the attack. The delay is measured in seconds.
Enable
This selects a control source to activate or deactivate the layer. When the assigned control
source is on (or above the midpoint of 64 for continuous controls) the layer will be active. The
layer will not sound when the control source is off or below its midpoint. For example, if you
wanted to create an octave doubler that would kick in on demand, you could create a program
with a second layer, transpose it up or down an octave, and set its Enable parameter to any
control source, like MWheel. Then whenever your MIDI controller's Mod Wheel is above its
midpoint, you'll hear the second layer. Some local control sources (e.g., KeyNum and AttVel)
are not valid for the Enable parameter. In these cases, you should use the global equivalent
(e.g., GKeyNum and GAttVel).
Enable Sense (S)
This lets you reverse the orientation of the MIDI control you've assigned to enable the layer. A
value of Normal has no effect on the Enable parameter, while Reversed will activate the layer
when the Enable control source is off or below its midpoint, and deactivate the layer when the
Enable control source is on or above its midpoint. You could use this parameter to set up a two-
layer program that would let you use a MIDI control to switch between layers, say a guitar
sound and a distorted guitar. Both layers would have their Enable parameters set to the same
control source, say MWheel. One would have its Enable Sense parameter set to Normal, and
the other would have it set to Reverse. Then the first layer would play when your MIDI
controller's Mod Wheel was above its midpoint, and the second layer would play when the
Mod Wheel was below its midpoint.
This is also the place to set the minimum and maximum values at which the layer will be
enabled. The two numbers to the right of the Enable Sense parameter are the Minimum and
