2. Click the source select field for source A and choose Import Audio.
The Import window opens.
3. Open the Apple Loops browser, and type “Lockstep” in the search field. Drag the
Lockstep Beat 02 loop to the Dropzone area of the Import window.
4. Click the Spectral and Formant analysis mode buttons at the lower left, then click the
Import button.
This determines the synthesis engine used for resynthesis of the audio sample. Spectral
+ Formant is a good general purpose option that works well for drum loops. It’s also the
default setting in a new instance of Alchemy. When analysis is complete, you can trigger
the loop at its native pitch by playing C3 on your keyboard.
5. Drag the Insider Groove Beat loop to the controls area of source B.
This alternative import method triggers the Import process automatically, using the
previously selected analysis mode.
6. Play C3 to trigger both loops at once. The loops are 8 beats long and have a native
tempo of 120, so playback is nicely synchronized. Although there are techniques for
tempo matching imported loops, it is simpler to use matched samples and improves the
potential for getting good results with minimal effort. If the loops have a very different
groove, click the Edit button to open the main edit window, where you can do any of the
following:
• In the waveform display, create warp markers to divide the loop into equal length
segments. The number of markers required depends on the length and complexity of
the loop. Aim to have a segment for each significant beat in the loop.
• Slide each warp marker forward or back as necessary to align it with the nearest
drum hit transient. Hold a warp marker in the waveform display to zoom horizontally
for more accurate adjustments.
• Switch to the other drum loop source with the A/B/C/D buttons at the top left of the
main edit window.
• Slide each warp marker forward or back as before to align each with the nearest
drum transient.
7. Click the A button (under Global), then choose Continuous from the source A Loop
Mode pop-up menu. Repeat this step for the source B loop.
This sets both beats to loop continuously while you hold down a note.
8. Turn off the Velocity On button in the modulation rack.
When triggering loops, it can be helpful to disable velocity control of the playback level
so the loops trigger with the same loudness regardless of how hard you play. If the
modulation area doesn’t show this parameter, click the Global button, then click the
center of the Master Volume knob shown at the upper right.
