Alchemy overview in MainStage

Alchemy is an easy-to-use, yet powerful sample manipulation synthesizer. It offers numerous real-time performance controls and an extensive preset library.

Alchemy features additive, spectral, and granular synthesis and resynthesis, sampling, and virtual analog engines. You can analyze imported samples and can manipulate them using one or more of these synthesis methods. Alchemy provides extensive sample mapping, looping, and grouping facilities that make it easy to create instruments containing hundreds of samples and layers. If you want to create purely synthetic sounds, the additive, spectral, and virtual analog synthesis engines are full-featured, matching or exceeding the power and facilities of many standalone instruments.

An Alchemy preset can contain up to four sources, each using one or more synthesis engines. You can morph or crossfade between these sources. Dozens of modeled analog and digital filters are available, in addition to multiple racks of integrated effect units and an extensive modulation section. Alchemy also features a powerful arpeggiator that can control each source independently and provides flexible pattern modulation options.

If you’re new to synthesizers and different synthesis methods, see Synthesizer basics overview. Also see the Alchemy tutorial introduction for MainStage for detailed tasks on the use of several advanced Alchemy synthesis features.

If you’re new to using plug-ins in MainStage, see Add and remove plug-ins in MainStage.

Before you can design new sounds with Alchemy you need to understand how its different parts fit together, and how each of them contributes to what you hear.

At first glance Alchemy may seem complex, but its layout is relatively simple:

The diagram shows signal flow from left to right through the different sound generating and processing modules.

There are three basic stages:

Each sound can contain up to four sources: A, B, C, and D. Each source consists of additive, spectral, granular, sampler, and virtual analog elements. Multiple elements can be active in each source. Each source has three independent filters that can operate in parallel or in series. These sources are used to create and shape the basic tone of the sound. All modulation in this section applies per voice. See Alchemy source overview in MainStage, Alchemy source filters in MainStage, and Alchemy source modulations in MainStage.
There are two main filters that can operate in parallel or in series. The main filters are used to shape or otherwise alter the combined sound from the four sources. All modulation in this section applies per voice. See Alchemy main filter controls in MainStage.
After the individual voices are mixed together and filtered, they pass through the effects stage. Any modulation of the Effects section is applied to the entire audio signal sent from the main filter section. You can also directly route sources (post source filters, if used) to the Effects section, bypassing the main filters altogether. See Alchemy effects overview in MainStage.

Working with projects from Logic Pro for iPad

Logic Pro for Mac provides playback compatibility with Logic Pro for iPad projects that use Sample Alchemy. You can load presets for this plug-in in Logic Pro for Mac Alchemy, but can only edit parameters in Sample Alchemy in Logic Pro for iPad.

To continue working with Sample Alchemy settings in Logic Pro for Mac, replace the plug-in with Alchemy. See the Share a project with Logic Pro for iPad topic in the Logic Pro for Mac User Guide, and the Export and Share projects chapter in the Logic Pro for iPad User Guide.

Replace Camel Audio Alchemy with MainStage Alchemy on a track

MainStage Alchemy settings are compatible with Camel Audio Alchemy. This enables you to replace the Camel Audio plug-in with MainStage Alchemy.

In MainStage, select the track with the Camel Audio Alchemy plug-in.
In the channel strip for the selected track, place the pointer over the instrument slot containing Camel Audio Alchemy, then choose Alchemy from the pop-up menu.
The new instance automatically retains your Camel Audio Alchemy settings.
Note: Because of updates to MainStage Alchemy controls and features, patches might not sound exactly the same as they did in Camel Audio Alchemy. Also, automation doesn’t carry over to MainStage Alchemy.
