• Open Logic Pro
• Open Solar Modulator
• You should see a notification showing one additional midi input is available
• Without needing any configuration, Logic should recognize basic MIDI messages from Solar Modulator on any channel.
• To map Solar Modulator to controls in Logic, you can either map the MIDI parameter directly to a control, or map it to a smart control.
• Mapping to a smart control is recommended because it gives you control over the minimum and maximum values and lets you invert or scale the MIDI input.
• In Solar Modulator select the MIDI parameter and channel you want to to use, select the control or smart control you want to map it to and select Logic Pro X→Control Surfaces→Learn Assignment for "[selected control]". The control will be mapped when Solar Modulator sends its next MIDI message.
• Note: this menu item requires "Show Advanced Controls" to be enabled in Preferences→Advanced.
• Note: it's recommended to use a otherwise unused MIDI parameter and channel for mapping and automation (like the General Purpose parameters) so you don't run into any side effects when recording automation
• See Logic's documentation for additional details on mapping and smart controls.
