To swap drum sounds, which action must be taken?

To swap drum sounds effectively, opening the plug-in and selecting a different sound from the library is the correct approach. Within the context of Logic Pro, drum sounds often reside within specific plug-ins, and these plug-ins allow for the selection and manipulation of different drum kits or individual drum sounds. By choosing a 'plus' version or an alternative drum sound from the library, users can easily replace one sound with another while preserving the overall arrangement and MIDI data.

This method ensures that you're not only swapping the sound but also maintaining the integrity of the performance, as the MIDI notes will trigger the new sounds without needing to alter the underlying MIDI information. It provides a straightforward and efficient way to customize drum sounds according to the requirements of the project.
