Before the iPhone and the iPad made multitouch screens commonplace, there was the Lemur, a multitouch controller for synths, sequencers, and other electronic music instruments. The device has been used by musicians for quite a while, and it combines a touchscreen controller unit running a version of Linux with all sorts of musical electronic wizardry. Now, the Lemur interface has arrived on the iPad as an app, and it will connect via Wi-Fi to up to eight different computers to run any musical sequencers you happen to have around.
I'm sorry to say that I'm not quite musical enough to use or buy an app like this,
