Logic Pro Alchemy extended parameters
Alchemy provides additional parameters that are accessed by clicking the disclosure
triangle at the lower left of the interface.
Extended parameters
• MIDI Mono Mode pop-up menu: Choose Off, On (with common base channel 1), or On
(with common base channel 16).
In either mode, each voice receives on a different MIDI channel. Per voice channels
support pitchbend, aftertouch, modwheel, and Performance control assignment
messages. See Logic Pro Alchemy performance controls. Controllers and MIDI
messages sent on the base channel affect all voices.
• Mono Mode Pitch Range slider: Set a value from 0 to 96.
The chosen pitch bend range affects individual note pitchbend messages received on
all but the common base channel. The default is 48 semitones, which is compatible
with the GarageBand for iOS keyboard in pitch mode. When using a MIDI guitar, 24
semitones is the preferable setting because most guitar to MIDI converters use this
range by default.
Alchemy tutorials
Logic Pro Alchemy tutorial introduction
The following sections contain information to assist you as you start to explore sound
creation in Alchemy.
Given the flexibility and variety of Alchemy synthesis engines, you can take a number of
different approaches to sound design.
• If you prefer to tweak existing settings, it may be more suitable to use features that
affect the entire instrument. At the simplest level this is achieved with performance
controls such as the Transform pad. See Logic Pro Alchemy basic synthesis tweaks and
Logic Pro Alchemy performance controls.
• If you prefer to build sounds from scratch—parameter by parameter—you can. See Logic
Pro Alchemy source overview and Create Logic Pro Alchemy sounds from scratch.
• Alchemy also features advanced morphing capabilities that facilitate cross-synthesis to
create new sounds. See Logic Pro Alchemy elemental morphs overview.
Whatever approach you favor, you can achieve new and interesting results. Experiment and
familiarize yourself with each approach. Each has its strengths and weaknesses, and often
a combination of methods may strike the best balance for your needs.
When programming a sound from scratch in Alchemy, the best approach is to work on each
component of the sound in isolation.
To start, you need a plain vanilla setting. You can revert to this setting by choosing File >
Initialize Preset in the Name bar. The default setting is sonically uninteresting but provides
a useful starting point for several examples.
