439 Live MIDI Effect Reference
For example, with Chance set to 100 percent, Choices set to 12 and Scale set to 1, playing
C3 once will trigger C3, and each successive C3 will trigger the next semitone higher until the
device reaches C4, at which point it will start over at C3. But with Chance set to 100 percent,
Choices set to 2 and Scale set to 2, incoming C3s will alternate between C3 and D3. This setting
is perfect for simulating upbow and downbow alternation with stringed instruments, or alternat-
ing right- and left-hand drum samples.
Hint: Try using the Scale effect after Random to constrain the output values to a specific har-
monic range. Using Random’s Alt mode with the Scale device allows you to create a simple step-
sequencer.
23.6 Scale
The Scale Effect.
Scale alters incoming note pitch based on a scale mapping. Each incoming note is given an
outgoing equivalent on the X-Y scale map of the effect: All incoming Cs, for example, might be
converted to outgoing Ds.
The X-Y scale map is 12 squares in length and width, corresponding to the 12 notes in a full
octave. Darker squares represent the black keys on a keyboard. The base of the diagonal scale
(the lower left square) shown on the map can be changed using the Base control. The X-axis
of the map shows incoming note values, and the Y-axis their outgoing equivalents. Use mouse-
clicks to move or delete the blue squares, which define where an incoming note will be sent on
the scale. (Deleting a note on the scale map means that it will no longer play.)
