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 alternating right- and left-hand drum samples.
Hint: Try using the
Scale
effect after Random to constrain the output values to a speci c
harmonic range. Using Random's Alt mode with the Scale device allows you to create a
simple step-sequencer.

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 yellow squares, which de ne where an incoming
note will be sent on the scale. (Deleting a note on the scale map means that it will no longer
play.)
The Range and Lowest controls work together to de ne the note range within which scale
