TotalMix FX for iPad is RME’s Windows/Mac software TotalMix FX ported to iOS. It gives control over the audio interface’s mixer and effects unit, when the interface is in Class Compliant mode and connected to the iPad. *** This app does not work wirelessly. For remote control of TotalMix FX running on a Windows or Mac computer, please use RME's free app TotalMix Remote. *** *** ATTENTION: This app works only with the RME audio interfaces Fireface UFX+, UFX II, UFX, UCX, 802, Babyface, Babyface Pro and MADIface Pro, and only when these devices are in Class Compliant mode! *** TotalMix FX for iPad runs on iPad2 or newer, and all iOS versions from 12.0 up, using only few resources. As under Windows and Mac OS X it does not process audio, but acts as remote control for the calculations performed in the hardware. The app is fully compatible even when storing/loading Workspaces. Except for MIDI/OSC and TCP/IP remote control all features of the desktop version are included. Using the Fireface UCX and Fireface 802 with the iPad, TotalMix FX for iPad unlocks the device’s whole functionality, with full overview and lightning fast configuration. For the Fireface UFX, UFX II and UFX+ the whole functionality is offered as well. Even DURec (Direct USB Recording) is fully usable and controllable from the iPad. The functionality of the Babyface, Babyface Pro and MADIface Pro is slightly limited due to technical reasons. The effects Reverb and Echo are not available. All other features are present and useable with iPad operation. The MADIface Pro supports 24 channels playback/record, 4 analog and 20 from MADI. TotalMix for iPad benefits from the background audio function in iOS. During ongoing recording and playback switch to TotalMix at any time, perform the desired settings or changes, then return to the audio app where record/playback had not been interrupted. The app includes an extensive and up-to-date help. More information on TotalMix FX and the Class Compliant operation of the devices is found in the current interface manuals.
