Delay Control
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 Minimum Delay and
MaxDly (described below). You’ll assign a continuous control like MWheel for the Delay
Control 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, Maximum Delay
The length of the delay is determined by these two parameters. When the control source
assigned to Delay Control is at its minimum, the delay will be equal to the value of
Minimum Delay. The delay will be equal to the value of Maximum Delay when the control
source is at its maximum. If Delay Control 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 assigns a control source to activate or deactivate the layer. When the value of the
assigned control source is between the minimum and maximum thresholds set by the Sense
parameter, the layer is active. When the value of the assigned control source is below the
minimum or above the maximum, the layer is inactive. By default, many layers have the
Enable parameter set to ON, so the minimum and maximum thresholds don’t matter.
They’re relevant only when Enable is set to a specific control source (like MWheel).
Some local control sources (KeyNum and AttVel, for example) are not valid for the Enable
parameter. In these cases, you should use the global equivalent (GKeyNum and GAttVel in
this example).
Enable Sense
This parameter determines how and when a layer is enabled by the control source assigned
for the Enable parameter. Enable Sense has three values: orientation, minimum, and
maximum.
Suppose for a moment that you’re editing a program, and in the current layer you’ve set the
value of Enable to MWheel, which causes the Mod Wheel to control whether the layer is
active. The default values for Enable Sense are as follows: orientation is Norm; minimum is
64, and maximum is 127. This means that when the Mod Wheel is less than halfway up, the
layer is disabled. The layer plays only when the Mod Wheel is more than halfway up.
Change the orientation to Rvrs, and the layer plays only when the Mod Wheel is less than
halfway up. Change the orientation back to Norm, and change the minimum to 127. Now
the layer plays only when the Mod Wheel is all the way up.
