Cubasis supports audio and MIDI hardware on all platforms, as well as plug-in and inter-app communication protocols on iOS.
On iOS, Cubasis is compatible with class-compliant audio and MIDI hardware, as well as other apps and plug-ins installed from the App Store through the AudioUnit (AUv3), Inter-App Audio (IAA) and Audiobus protocols.
On Android, Cubasis detects some audio and MIDI hardware, but due to the lack of standards it cannot detect all class-compliant devices, and there is no support for plug-ins. Follow the instructions in the support article if you experience issues with an audio device on Android.
To sync several devices to the same tempo, Cubasis supports Ableton Link on all platforms.
