Modulation PatchCords
Random Sources
Random modulation sources can be used when you want the timbre of the
sound to be “animated” in a random or non-consistent manner.
•
Key Random 1 & 2
generate different random values for each layer
which do not change during the note.
•
The
White & Pink Noise
Generators produce varying random val-
ues. Both white and pink noise sources are low frequency noise
designed for control purposes. Either noise source can be filtered even
more by passing it through a lag processor.
•
The
Crossfade Random
function generates the same random value
for all layers in a preset. This source is designed to be used for cross-
fading and cross-switching layers, although you may find other uses.
Modulation
PatchCords
When setting up modulation with the XL-1, you define a modulation
source and a modulation destination. Then, you connect the source to the
destination using “PatchCords.” XL-1’s PatchCords are connected in the
software. Xtreme Lead has 24 general purpose PatchCords for each layer.
The controller Knobs
assignments printed on the
front panel are the system
defaults. You can change any
of these assignments using the
Real-time Controller
Assignment page in the Master
menu (see page 83 for details).
You can connect the modulation sources in almost any possible way to the
modulation destinations. You can even modulate other modulators. Each
PatchCord also has an amount parameter which determines “how much”
modulation is applied to the destination. The modulation amount can be
positive or negative. Negative values invert the modulation source.
