There are a few things you can try to speed up the load time for your MPC Live 2 projects:
1. Use smaller sample sizes: Larger sample sizes take longer to load, so try using smaller sample sizes when you're creating your projects. This can help reduce the load time for each project.
2. Optimize your project settings: Check the settings for each of your projects to ensure they are optimized for performance. Make sure your audio settings, sample rate, and bit depth are set correctly for your specific use case.
3. Use a faster SD card: The speed of your SD card can have a significant impact on the load time for your projects. Consider upgrading to a faster SD card if you're currently using a slower one.
4. Consolidate your projects: If you have multiple projects that use the same samples or sounds, consider consolidating them into a single project. This can help reduce the overall load time for your live set.
5. Use the "standby mode" feature: The MPC Live 2 has a "standby mode" feature that can help reduce the load time for projects. With this feature enabled, the MPC will keep the last project you used in memory, allowing you to quickly switch back to it without having to reload it.
Hopefully, one or more of these tips will help you speed up the load time for your MPC Live 2 projects and improve your live performance experience.
