2. Switch to advanced view, and set up each of the four sources with a different, but
complementary sound.
Feel free to use any of the synthesis engines for each source or to blend multiple
engines within one source.
3. Click the Morph button at the left to view morphing parameters, then click the XFade XY
button.
4. Make sure the X knob is set to zero, then Control-click the X knob and choose Add
Modulation > Perform > XYPad1X from the shortcut menu.
5. Make sure the Y knob is set to zero, then Control-click the Y knob and choose Add
Modulation > Perform > XYPad1Y from the shortcut menu.
Morph four spectral sources using an X/Y pad performance control in
Alchemy
Follow these steps to use the left X/Y pad in the performance controls section instead of
the X/Y pad in the morph section. This allows you to control crossfades between sources in
simple view and also allows you to include these modulations in Transform pad snapshots.
1. In Logic Pro, from the Name bar, click the File button and choose Initialize Preset from
the pop-up menu to reset all Alchemy parameters to default settings.
2. Switch to advanced view, then click the Morph button at the left to show morphing
parameters.
3. Click the source A select field, and choose Import Audio.
4. Select Spectral mode in the Import browser, choose a suitable sample, and import it.
Turn on Formant mode before importing.
5. Repeat steps 3 and 4 for each of the other three sources. Make sure Spectral mode is
chosen and the Formant button is on when importing to sources B, C, and D.
6. Click the Morph button at the left to view morphing parameters, then click the Morph
XY button.
You can now morph between the four sources using the X and Y knobs. Follow steps 7
and 8 to assign the X and Y knobs to the left X/Y pad in the perform section.
7. Double-click the X knob to set it to zero, then Control-click the X knob and choose Add
Modulation > Perform > XYPad1X from the shortcut menu.
8. Double-click the Y knob to set it to zero, then Control-click the Y knob and choose Add
Modulation > Perform > XYPad1Y from the shortcut menu.
Create a linear morph between two speech samples in Alchemy
1. In Logic Pro, from the Name bar, click the File button and choose Initialize Preset from
the pop-up menu to reset all Alchemy parameters to default settings.
2. Switch to advanced view, then click the Morph button to show morphing parameters.
3. Click the source A select field, and choose Import Audio.
4. Locate the first of your speech samples and import it, using Additive, Spectral, or
Add+Spec mode. Turn on Formant mode before importing.
5. Repeat steps 3 and 4 for source B and your second speech sample. Use the same
import mode as for the first sample, and make sure Formant mode is active.
