9. Drag the handle between the two sources while holding a note to hear the sound morph
from the vocal (source A on the left) to the synth lead (source B on the right).
10. Click the Elements button to show the elemental morphing controls, then move the
Pitch handle (green dot) to the far right while holding down C3 on your keyboard. You
can also rotate the Pitch knob.
When the note cycle restarts, you will hear the vocal sample “singing” the melody
provided by the synth lead phrase in source B. The pitch morph is particularly effective
because the source A material contains no chordal content and does not change pitch,
and the Source B material has a very clear melodic phrase that the pitch analysis can
easily track. In general, files that work well for Flex Pitch in Logic work well for pitch
morphing applications in Alchemy. Keep this example loaded for the next task.

Elemental morphing can sometimes lead to sudden and dramatic level changes. Before
adjusting the Additive control, click the Global button, then double-click the Volume knobs
for sources A and B. This sets them both to -18dB.
1. In Logic Pro, click the Morph button at the left to show the morphing section at the
upper right, then click the Morph Lin button, the A-B button, and the Elements button (if
required).
2. Drag the Additive handle (blue dot) to the right while holding C3 on your keyboard. You
can also rotate the Additive knob to set this value.
As you move the control, the harmonic partials of the vocal sample transition to the
partials of the synth lead. This doesn’t always produce pleasing results because partials
in one sound may emphasize noise or artifacts in the other sound. The workflow is often
one of sonic exploration in search of happy accidents rather than a predictable process.
Play notes and chords above and below C3 as you experiment.
3. Set the Additive control to approximately 30%, Pitch to 100%, and Formant and
Envelope to zero percent.
4. Click the A button at the left to view source A parameters, click the Additive button at
the top right, then rotate the Fundamental knob toward the left.
This attenuates the fundamental partial which brightens the sound by making the higher
frequency partials more pronounced.
Turn down the Odd/Even knob to create a more hollowed out sound, emphasizing the
partials of the synth lead. Experiment with other controls to get a feel for their effect on
the sound. Play octaves and fifths as you experiment.
