918 Chapter 38 Working in the Environment
Controller Base
All ten parameters of the arpeggiator object can be remote-controlled with MIDI
continuous controller events. The Controller Base parameter determines the controller
number for the first parameter (Direction). The other parameters will be controlled by
subsequent controller numbers.
When Controller Base is set to Off, MIDI control of the arpeggiator is disabled.
Transformer Object
You can use a transformer object to select, filter, and alter MIDI events in real time.
Transformers can also process meta events, as long as they are not the meta events
that affect transformers. These particular meta events change the transformer, rather
than being processed by it. For more information, see “Controlling the Condition and
Operation Values via Meta Events” on page 922.
To create a new transformer object:
m Choose New > Transformer (or use the New Transformer key command).
How the Transformer Object Works
A transformer object checks whether or not an incoming event matches certain
conditions. If it does, then certain operations are carried out.
Events which do not meet the conditions may pass unchanged to the output, or may
be discarded.
The transformer can also make copies of matching events before altering them, and
can split the selected (matching) events from the unselected ones, via its two top
cables.
You must place the transformer in the MIDI signal path in order to use it.
If you wish to alter the output of an instrument, for example:
1 Cable the instrument output into the transformer (removing the instrument’s internal
port assignment in the process).
2 You will need to create a New > Instrument, and assign it to the desired MIDI output
port.
