MidiController turns your iPhone/iPad into a complete MIDI controller, that works over USB, WLAN or Bluetooth. No additional software needed! Send all possible Notes, Continuous Controller / Control Change and Program Change values to the connected device. Build your workspace from the ground up with unlimited, custom Pushes/Buttons and Sliders. All Pushes/Buttons and Sliders are completely customisable - customize every value of every control possible and how the control behaves. You can even create dynamic controls (e.g. Program Change values that count up or down). • Works with every macOS: From 10.5 (Leopard) up to the newest 10.15 (Catalina) • Works on every iPhone and iPad • Also works with external hardware (e.g. synths,...) that supports Apple (CoreMidi) • If your hardware/PC does not support CoreMidi, you can use an iPhone/iPad compatible MIDI-Interface as bridge to make MidiController work with ALL MIDI devices Works with every application that supports MIDI-Input. Example DAWs (Digital Audio Workstation): * Logic X Pro * Ableton Live * Avid Pro Tools * Propellerhead Reason * Steinberg Cubase * Cockos Reaper * and many more (in principle every application that supports midi input) ** NOTES ** • MidiController does not play any sound itself, it only sends out MIDI-Information to connected devices. • MidiController is primary created to work with macOS-Devices. If you want to use MidiController with hardware that does not support Apple CoreMidi, you might need an iPhone/iPad compatible MIDI-Interface as bridge. A MIDI interface typically connects to your iOS per lightning port and provides standard MIDI DIN ports to connect to your hardware. There are also bluetooth MIDI interfaces that connect wirelessly. • MidiController does not receive any MIDI-Information, it generates and sends them itself depending on the user-input. ______________________________________________ APP USAGE INFO & MIDI CONTROLLER SUBSCRIPTION DETAILS Should you choose to upgrade to a midi controller subscription, payment will be charged to your iTunes account at confirmation of purchase.
