MIDIMixer for iPad works as external MIDI-Controller providing 24 channel strips separated into 2 Mixer-Banks consisting of Mute- and Solo-Buttons as well as Stereo-Panorama-Fader and Level-Fader.
Free configurable text fields allow the individual labeling of each channel strip. The app sends MIDI-Control-Change commands to be learned by your favorite Digital Audio Workstation (e.g. Logic, Cubase, etc.) running on Mac OSX or Windows (Apple’s Bonjour for Windows and rtpMIDI needs to be installed).
