As you explore the included sound library, you may notice that many presets have a similar
performance control layout. Some presets may require special performance controls, but
the following guidelines work well for most presets.
• Control knobs: Provide quick access to a sound’s main characteristics. You can assign
knobs to other parameters in advanced view.
• Knobs 1 and 5: Often used for Delay (1) and Reverb (5) level. If other effects are
used, other effect parameters can be substituted here. Control of effects mix levels
should take priority over other parameters, assigned to Knob 1.
• Knobs 2 and 6: Often used for filter cutoff and resonance. If your preset doesn’t use
a filter, you might consider adding one in a fully open state in the effects section.
• Knobs 3 and 7: Often used to control rhythm or movement in a preset with LFO or
arpeggiator parameter assignments.
• Knobs 4 and 8: Often used for timbre, pitch, or other source parameters.
• XY pad 1: Generally used for morphing among sources. If more than one source is used,
this XY control is the place to assign control of morphing or crossfading.
• XY pad 2: Can be used for control over additional morphing or effects parameters or for
features unique to a particular preset.
• Envelope knobs: Normally control the corresponding parameters in AHDSR 1. You can
reassign to other parameters in advanced view.
• Mod wheel: Typically linked with the most playable performance control and should
always be functional for the first snapshot. Take care with modwheel assignments to
make sure settings of 50% or lower don’t cause undesirable results, such as a dropout
of the sound (from a very low minimum lowpass cutoff setting, for example). This is
particularly important if your MIDI controller has a spring-loaded joystick.
• Octave: Turn off if you want to play your sound across the entire keyboard range.
• Aftertouch: Should always be assigned to something useful for the preset.
Logic Pro Alchemy Transform pad
When simple view is active, or if the Perform button is on in the Perform/Arp/Effects
section in other views, the performance controls subpage is displayed.
Alchemy presets contain eight snapshots of performance control settings, numbered 1 to
8. By default, snapshot 1 is selected. This is indicated by the framing box.
