MIDIPad is officially “coming soon”. Here’s what its developers have to say about it:
The striking feature of midipad is its ability to directly communicate via network-MIDI-protocol. So there is no need to install any communication-peer-software on the Mac! Simply plug-and-play via Apple Bonjour – wireless.
This multitouch-capable midi-controller-application communicates with your Apple Mac your Windows-based PC and even standalone hardware-synths via Wifi.
So you can control all of your music-applications with just a few finger-gestures without having to sit at your desk and no annoying cable.
In the production-environment midipad can control host-applications like Apple Logic, Steinberg Cubase/Nuendo, Ableton Live etc.
It can also be used to control stand-alone applications from companies like Native-Instruments, Spectrasonics and many more.
