hubbub – noun – A loud confused noise from many sources.
The Hubub is a fitting moniker for our current iPad-based guitar system project; a melange of synth sounds, MIDI signals, analogue guitar, and the digital mayhem that ensues.
It’s doubly appropriate since a customized USB hub will be required to make it all possible, or at least practical. A primary goals of this setup is that it should run entirely from rechargeable batteries, sans power leads. It’s a lofty, but worthwhile goal. Over the next few weeks we shall see if that goal is achievable in a cost-effective way.
To the right is a diagram of the planned system. The main challenge of this computer-less approach is maintaining power for the iPad. Powering the USB hub, and the devices attached to it, from a battery is easy enough. But music software tends to drain an iPad battery quickly, so we want to be able to charge the iPad while in use. There doesn’t appear to be a product available that accomplishes this goal without a computer somewhere in the mix.
But we are working towards a solution. Soon many, if not all, of the devices below will be happily hooked up to an iPad air, buzzing along from rechargeable batteries.
