485 MIDI and Key Remote Control
this, since its incremental message to Live would simply say, ”Pan slightly to the left of your cur-
rent position.”
There are four types of relative controllers: Signed Bit, Signed Bit 2, Bin Offset and Twos Com-
plement.
Each of these are also available in a ”linear” mode. Some MIDI encoders use ”acceleration”
internally, generating larger changes in value when they are turned quickly. For control surfaces
that are not natively supported, Live tries to detect the controller type and whether acceleration
is being used or not.
You can improve the detection process by moving the relative controller slowly to the left when
you make an assignment. Live will offer its suggestion in the Status Bar’s ”mode” chooser, but if
you happen to know the relative controller type, you can manually select it.
Live will do the following with relative MIDI controller messages:
•Session View Slots — Value increment messages are treated like Note On messages. Value
decrement messages are treated like Note Off messages.
•Switches — Increment messages turn the switch on. Decrement messages turn it off.
•Radio Buttons — Increment messages make the radio button jump forward to the next
available option. Decrement messages make it jump backward.
•Continuous Controls — Each type of relative MIDI controller uses a different interpretation
of the 0...127 MIDI controller value range to identify value increments and decrements:
Please consult the documentation that came with your MIDI controller if you need further infor-
mation on relative MIDI controllers.
Relative Session View Navigation
Notice that you can make not only absolute mappings to individual slots and scenes, but also
relative mappings to move the highlighted scene and operate on the highlighted clips.
In both MIDI Map Mode and Key Map Mode (page 487), a strip of assignable controls ap-
pears below the Session grid:
