The new Lemur software is by far the most advanced touch screen controller software out there, as it gives users the ability to create scripts for their controllers, and build intelligent systems much like in Max/MSP or Reaktor. Lemur communicates either over Wi-Fi, or USB MIDI. It's important to note that the software is compatible with Open Sound Control, which is a control protocol much like MIDI, with significant advantages. The latency is much lower, the resolution is higher, and frankly, it can be even simpler to set up. The downside of OSC is that most software (such as Ableton Live) doesn't support it. It's useful with programs like Max/MSP, Max 4 Live, Csound, Reaktor, and Modul8. Most users will connect the Lemur software to their computers using an ad hoc network, which is a decentralized wireless network coming from your computer that your iPad can connect to...
