Create envelope morphs in Alchemy
The Envelope control in the morph section primarily morphs between the timing of sources.
This has little effect when files are close in length, but this behavior changes when the
playback length of files is altered.
1. In Logic Pro, click the Morph button at the left to show the morphing section at the
upper right, then move the Envelope handle (yellow dot) to the far left. You can also use
the Envelope knob to move the Envelope handle.
2. Click the A button at the left to view source A parameters, and click the Edit button at
the right of the source filename.
The source A edit window opens.
3. In the waveform editor at the bottom of the main edit window, drag the E handle to the
very end of the audible part of the waveform.
This effectively removes the silence at the end of the vocal phrase by reducing the
playback length of the overall file.
4. Play C3 on your keyboard, and note that the phrase plays faster because the timing for
the sound is currently based on the timing of the vocal sample.
Also note that you can hear the entire synth lead phrase, which no longer fades away at
the end. If you move the end marker further left, you can hear the entire phrase of the
synth part played faster.
5. Click the X at the upper right to close the source A edit window.
6. Return to the morph controls, and adjust the Envelope knob to hear how it affects the
behavior of samples with different lengths.
