What’s new in Logic Pro 10.6. What’s new in Logic Pro 10.5. I just bought a Jamstack amp and it has me using the Tonebridge app. Unfortunately the tonebridge app doesn’t work with any of my guitars. When sound does come out, it’s very low and I have to turn the effect all the way to the max to get anything to come through but then when I play the demo it sounds perfect through the amp/app. By setting the buffer size and range, you can help your Mac understand how important Logic is at any time. To do this, go to Logic Pro X Preferences Audio This is the Audio Preference menu. Home to all things related to how Logic manages incoming and outgoing audio. Even though Logic Pro X offers a shredload of plugins that can make great guitar tones (or can be used creatively for distorted vocals for example), there's a whole other world of third-party guitar amp simulator plugins to explore. Here's an overview of some of the best free guitar amp.
Before proceeding, make sure to back up the Logic Pro app.

Check device or software compatibility
If you're using an external audio interface, MIDI interface, storage system, control surface, or plug-in not made by Apple, make sure that it’s compatible with the latest version of Logic Pro. Contact the manufacturer for support. If an update is available, follow the manufacturer’s instructions to update the device or software.
Use built-in audio with Logic Pro
If you’re using an external audio interface, try using the built-in audio on your Mac instead of the interface.
- Unplug your external audio interface from your Mac.
- Open Logic Pro, then choose Logic Pro > Preferences > Audio/MIDI > Devices.
- Choose Built-In Output from the Output Device pop-up menu.
- Choose Built-in Microphone (or Built-in Input, depending on your computer) from the Input Device pop-up menu.
- Open and play back a project that's been experiencing issues.
If the project opens and plays back properly, you might need to update or service your audio interface. Contact the manufacturer for support.
If you aren’t using an external audio interface, try bypassing third-party Audio Units plug-ins.

- Open Logic Pro and immediately press and hold the Control key before a project opens.
