Neyrinck has released V-Control Pro 1.7 for iPad. With this app you can control many digital audio workstations (DAW) on the iPad, including Cubase, Logic, ProTools, Ableton Live and Reason. Special about V-Control Pro is that the computer screen can be projected directly on the iPad. Plug-ins are displayed in a separate window, including the graphical user interface (GUI). See the introduction video below:
V-Control Pro costs 45 euro. There is also a free version available, so you can check out whether the app works well with your computer. Tip: turn the Bluetooth off, this can cause delays.
