iOS 14 and PadOS 14 are both confirmed compatible with Playback.
The latest version of Playback can be installed on devices that support iOS 10 and above, which include:
iPhone 5 and above
iPad Gen 4 and above
iPad Air and above
iPad Mini 2 and above
Important note about the oldest generation of compatible devices
(iPhone 5, iPad Gen 4, iPad Air, and iPad Mini 2): In order to prioritize a stable Playback experience, some memory-intensive features in the Premium Subscription are limited. We recommend using a newer device to unlock more advanced features, including MultiOuts and editing MIDI Cues in Playback.
