Logic Pro Alchemy morph use and tips
Source components are shown only in advanced view. Click the Advanced button to switch
to advanced view, then click the Morph button to view and use the morph controls. See
Logic Pro Alchemy morph controls.
It is important to choose the same analysis mode for all morphed sources. See Logic Pro
Alchemy Import browser.
Though you can morph with any synthesis type, the best morphing results are achieved
with the spectral or additive engines. Spectral is the most suitable import method to use
for the majority of audio material. Use Additive or Add + Spec import mode if dealing with
pitched, monophonic sounds. Make sure the Formant button is turned on when importing
sounds because this generally results in a higher quality morph.
If you are not creating a pitched instrument that requires the root note to remain at the
default pitch, irrespective of the morph position, turn off the Fixed Pitch button, because
this will result in a higher quality morph.
The time alignment of sounds is crucial to achieving a good morph. Selecting sounds with
similar timing and loop characteristics tends to deliver the best results. Aim to have a
similar loop duration and loop location within the selected samples. If the sounds you are
morphing are comprised of more than single note samples or the timing of your sources
doesn’t align as you would like, adjust the warp marker positions. See the Manually time-
aligning morphed sounds task in this section.
Morphs that move from 100% of all elements in a sound to 100% of another sound can
often be suitable for sound effects but may be more difficult to shape into new playable
instruments. You may find it better to mix the levels of individual elements for this type of
use.

Manually time-aligning morphed sounds in Alchemy
This task covers manual alignment of sources. Alchemy features an auto align function (see
Logic Pro Alchemy morph controls) that can make this an automatic process, but in some
cases you may need to manually intervene to achieve the best results.
When morphing is turned on for a source, warp markers are displayed in the zone waveform
editor. See Logic Pro Alchemy zone waveform editor.
When you morph from a sound with a fast attack to one with a slow attack, Alchemy
smoothly adjusts the attack time according to the morph all position, or the envelope
position if in elements mode. Warp markers define the attack phase boundaries of each
sound. More generally, warp markers define the boundaries of a series of time-aligned
segments when two or more sounds are morphed together.
