Audiobus: Use your music apps together.

What is Audiobus?Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Audiobus is the app that makes the rest of your setup better.

usually we charge our iPads at home, having a reliable power grid. But what if we are outdoors for days, weeks, months, years? Are there any affordable solutions? From what I know, there are three different solutions:

  • solar panels
  • thermoelecticity
  • wind and water current

Now for the solar kits, there are already a couple of products on the market. What they all have in common is a) low efficiency, b) energy loss with additional batteries and converters. These are the downsides, the advantages are that they are available and - for small devices - acceptable for continuous use.

Thermoelectric energy supplies are quite efficient (just think about the amount of energy of a small campfire), but the products on the market are mainly targeted for phones and mp3 players.

Generators driven by wind or water currents have to be built by the user, I don't see any products in this range.

In short, there aren't many good solutions available for mobile computing including laptop and periphericals. One may buy a solar kit with huge panels and battery/converter, but this gear is heavy and not very cheap; it has to be transported with a car or bus.

What do you think about it? Do you know of any good solution? is there anyone with real-life experience in this matter?

    yes, the foldable panels are nice, but again they are what I believe not as high tech as could be possible. In countries with a lot of sun they may work quite well, but in other climates where there may be several weeks with clouded sky not so good. But I don't have much experience either, that's why I'm asking.

  • Very interesting Phil.something I touched upon a while back.
    The solution ive been considering is to stick marine solar panels on the roof of the camper van...they come in a roll with an adhesive back.

    These would keep the leisure batteries topped up while stationary and charge the power gorilla for use out an about.

    The biolite is also handy.

    But if your thinking of going off grid permanently,see the videos of the wood mans cottage...

    He's got his solar panels linked to a old submarine battery!

    iPad and iPhone are not well visible in these photos, but they play an important part in the setup. iPad mostly for Cubase IC Pro for the Windows tablet running Cubase 8 Elements demo, and iPhone for a Lemur controller for Shuttle Control. But there are many more things these devices do.

  • Oh sweet! I've recently taken to walking around in parks for inspiration while padding it up but this is a whole other level. Cool man!

  • This is a real dream setup, very inspiring-!

  • I must admit that it is indeed a dream setup. It simply works. And I didn't know beforehand. It's an experiment, and it succeeded. I'm incredibly happy with it.

    And the modules, I'm quite speechless. They are fantastic. A whole new level for me, I haven't known such powerful sounds, despite the fact I'm experienced with (old, ordinary) modular systems.

    It appears that I'm really pioneering here, and it is my intention to show people what is possible today, technically. Five years ago it was simply not possible.

    People ask me about the costs of solar systems. They are not cheap, but I would like to say affordable. Similar to Eurorack modules. With a few hundred bucks you can get one. And then you can be off the grid whenever you want. These panels work (charge) even in bad weather. For a single iPad even more affordable solutions are available, about 100-200 dollar.

    One thing is important, next to efficient solar cells and modern lithium-based power packs: the charge controller. If a cheap solar system has no charge controller, it will only charge at absolute ideal conditions. I recommend to check precisely about that. And check the amount of Watts the panel provides. A recent iPad needs at least 2.5A at 5V, which is more than 12W.

    Just found this

  • I am AMAZED that you are able to keep everything dry and alive. Has the weather been nuts for you this summer? It's nothing but heat and rain in the Northeast USA

    I even left the tipi with most of the equipment for a week, and I'm sure that everything will be in place when I arrive tomorrow. Weather generally was very calm this summer. Between 15° and 25°C during night and day, no extremes. Only short thunderstorms.

    But of course I monitor the weather when I'm not there. And change my plans in case of heavy rain and such. Until now I never lost a piece of gear, also thanks to friends who carry the timelapse-camera inside when it starts to rain in the morning. Don't challenge your luck, always keep an eye open for your equipment, wherever you are.
