The Remix FX (DJ-style filters, bit crushers, and gaters) introduced in earlier versions gets a latency fix in 10.4.8. For musicians using GarageBand as a live performance tool via the Live Loops grid, version 10.4.8 reduces the trigger latency to sub-10ms when using an external MIDI controller. This makes the software genuinely usable for live electronic sets.
This version ensures complete harmony between your DAW and the latest macOS environment. garageband 10.4.8
