Programming Basics
Modulation Sources
Modulation
Sources
Modulation sources include
Envelope Generators, Performance Controllers
and
Low Frequency Oscillators
. In the previous example, an envelope generator
was routed to automatically turn the volume control as programmed by the
envelope, or, a low frequency oscillator could be routed to turn the volume
control up and down in a repeating fashion. The following is a list of the
modulation sources used in XL-7.
Keyboard Key
Which key is pressed. Sometimes referred to as, “Keyboard Tracking”.
Key Velocity
How fast the key is pressed.
Release Velocity
How fast the key is released.
Gate
High if the key is pressed, low when the key is released.

Tip:
Try routing Key
Glide to Filter Frequency if you
want the filter to smoothly
follow pitch in solo mode.
Routing Key Glide to Pan creates
another interesting effect.
Key Glide
A smoothly changing control source based on the Glide Rate and the
interval between the last two notes played.
Pitch (Touchstrip) and Mod Controllers
Synthesizer pitch bend and modulation controllers.
Keyboard Pressure (mono aftertouch)
Key Pressure applied after the keypad is initially pressed.
Pedal
A continuously variable pedal controller.
Miscellaneous Controllers A -P
Any type of MIDI continuous controller data.
Low Frequency Oscillators (2 per layer)
Generate repeating waves.
Envelope Generators (3 per layer)
Generate a programmable “contour” which changes over time when a key
is pressed.
Noise & Random Generators
Generate spectrums of noise and random signals.
Footswitches
Change a parameter when the switch is pressed.
Clock Divisor
The master tempo clock can be divided and used as a modulation source.
