• ไดรเวอร์: Essential for your computer to recognize and communicate with the Forte.
• Forte Control: This application allows you to manage settings such as input gain, phantom power, monitoring mixes, and routing.
• Midnight Plugin Suite: Install these plugins into your Digital Audio Workstation (DAW) for additional audio processing capabilities.

4.3. System Optimization (Mac Specific Recommendations)

For optimal performance, especially on Mac systems, consider the following adjustments:

• Energy Saver Settings: Deactivate power-saving options. Go to System Preferences > Energy Saver. Set "Computer sleep" and "Display sleep" to "Never." Untick "Put hard disk(s) to sleep when possible."
• การเลือกพอร์ต USB: Connect the Forte directly to a USB 2.0 port on your Mac. Some Mac models may have specific USB ports that perform better for audio devices. Use Apple's System Profiler (Applications > Utilities) to identify the internal USB configuration and avoid sharing the Forte's port with the iSight camera or other high-bandwidth devices.
• ความยาวสาย USB: Use a USB cable no longer than five meters; three meters is generally recommended for stability.
