Choosing a different mode results in source A and B alternately playing in unison or
playing intervals from within the chord you play. Try setting one of the arpeggiators
to Random mode to add a level of unpredictability. Choose different Rate settings to
change the playback timing of sources. Try combining a straight timing for one source
with a triplet or dotted timing for another to create complex polyrhythms.
8. Repeat steps 5-7 for sources C and D if you require additional arpeggiated sources.
Note: You need at least four note polyphony to hear all four arpeggiated sources at
once. See Logic Pro Alchemy master voice section.
Create a more complex arpeggiator pattern using the sequencer section
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. Click the Arp button to show the arpeggiator section. All is selected by default.
3. Turn the Mode knob to select Up, Down, Up/Down, or Down/Up mode.
4. Click the Step button to switch to step edit mode, then choose Velocity from the pop-up
menu.
5. Adjust step levels for the Velocity sequence to introduce volume changes. Try turning
down all even numbered steps for a groovier feel, or Option-click specific steps to
disable them, thus creating a rest for that step.
6. Choose Length from the pop-up menu to display the length sequence. Experiment with
shorter or longer notes for different steps: try lengthening odd numbered steps and
shortening even numbered steps to enhance the groove.
7. Try tying a step to the next step by clicking the link symbol at the bottom. Experiment
with tying different steps to generate different rhythms and with tying multiple
subsequent steps to create a long note that spans several steps.
Create a step sequencer style pattern with pitch glides 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. Click the Arp button to show the arpeggiator section. All is selected by default.
3. Turn the Mode knob to select Up, Down, Up/Down, or Down/Up mode.
4. Set the Rate knob to 1/4. You can also choose to use a small Swing knob value to create
a looser feel.
5. Click the Multi button to switch to Multi edit mode.
6. Turn off several steps in the top Gate row to create a different rhythmic pattern. As an
option, you can also adjust the Pan knobs to position steps left or right in the stereo
field.
7. Click buttons in the Tie row to tie two or more steps.
8. Drag vertically in a Tune field for one of your tied steps. This results in a pitch change
partway through the note. Values of +/- 12 semitones can work well to produce octave
shifts up or down, but other values can also produce useful results: try +7 semitones for
example, or -2.
