247 Instrument, Drum and Effect Racks
The chain select zone is a data filter just like the other zones; although all chains in a Rack re-
ceive input signals, only those with chain select zones that overlap the current value of the Chain
selector can be addressed and thereby produce output.
By default, the chain select zones of Instrument and MIDI Effect Racks filter only notes, ignoring
all other incoming MIDI events (such as MIDI CCs). To filter all MIDI events, enable the Chain
Selector Filters MIDI Ctrl option, available in the context menu [right-click](PC) / [CTRL-click]
(Mac) of a Rack’s Chain Select Ruler.
In MIDI Effect Racks, fade ranges attenuate the velocities of notes entering a chain. In Instrument
Racks and Audio Effect Racks, which both output audio signals, fade ranges attenuate the vol-
ume level at each chain’s output. So what happens, then, if the Chain selector is moved outside
of the chain select zone where a sound is currently playing? If the zone ends in a fade range, the
chain’s output volume is attenuated to zero while the Chain selector is outside of the zone. If the
zone had no fade range, the output volume is not attenuated, allowing the chain’s effects (like
long reverb tails or delays) to fade out according to their own settings.
Let’s consider how we can make use of chain select zones in a performance situation:
Making Preset Banks Using Chain Select
Using Chain Select Zones to Create Effects Presets.
Unlike the other zone types, the default length of a chain select zone is 1, and the default value
is 0. From this setup, we can quickly create “preset banks“ using the Chain Select Editor.
Again, we will use a Rack with four chains as our starting point. Each of the four chains contain
different effects that we would like to be able to switch between. To make this a “hands-on“
experience, we have MIDI-mapped the Chain selector to an encoder on an external control
surface.
