After the announcement of the iMovie app for the iPad 2 it only made sense to continue the port of the iLife features to the device. Next came the announcent of GarageBand for the iPad, a program that seemed just as difficult to port to a mobile version as iMovie was.
The iPad GarageBand app will include an eight track recording format with more than 250 loops built in. There are a few mild features along with this such as the ability to email yourself an AAC file directly out of the software. The files will also be compatible with the version of GarageBand found on Mac computers.
The real major part of the iPad GarageBand announcement minutes ago was that it included a touch instrument features, that let you play instruments strait from the iPad. This is what the announcement was really built around as Xander Soren went through different instruments and showed us how to play them through the touch screen. This included piano types, guitar, bass guitar, and drums, all of which with complete controls and the ability to choose things like amp type.
This is really a major step forward for the device in that it will allow for not just live playing of simulated instruments through its virtual interface, but also immediate recording of this. Since it can be integrated directly into the GarageBand workflow on your home computer allowing that to act as a central hub while you are still developing tracks mobilely.
