Things like midi controller apps and streaming video apps etc rely on having a wifi network to work.. I'm wondering with those sort of things, if I tether my iPhone to my laptop and to my iPad (wifi only model), is that creating a wifi network that would allow my iPad and laptop to do the sort of things mentioned above?
I haven't really got any of those sort of apps (lemur etc) but would be interested if this worked..
Thanks

I have been using my iPad 2 as a Midi controller over a wireless connection to a Windows 7 64-bit PC. I hear the setup is rather easy with Macs; with PC you need to get a free Wireless Midi manager called rtpMidi and you have to have Bonjour installed on your computer (which I hear is pretty standard, my PC already had it..). The other little bit is that although many ios music apps support a wireless Midi connection, I have only found that many do not send a "I want to connect" signal to rtpMidi... I use the ios app MidiBridge to handle this and to assign the correct IP address (not sure about Lemur on this matter, I don't use it).

I use Thumbjam and Geo synth to control VSTs in my DAW and I have found it works smoothly and has no humanly noticeable latency (aside from when things get 'hung up' and I need to hit the panic button). In cases of a wireless network that is slow and causing latency you can also set up and ad hoc network.

Not sure about video streaming...

You can get rtpMidi here:

Thanks for that info, my main question as to whether having iPad and laptop connected via iPhone tethering constitutes a workable network alas isn't answered yet.
(does this mean I'll have to try work it out myself when I get home! )

Ah... Read that more closely now...

It sounds like your goal is to setup a wireless connection between your laptop and your iPad in a location with no wireless network? So why not just set up an ad hoc network? Your laptop can most likely host a session that your iPad can log into..

Unless your goal is to have access to the wider internet via 3G/4G at the same time as your wireless session... in which case, best wishes on your journey unto tetherdom!

Thanks, that sounds a better option if i can figure out how to do that

Are you working with a Windows PC? If so here is a great guide:

Setting up an ad hoc network takes a bit of effort and more than a couple of steps, but I think you will find it worthwhile.

If you are working on a Mac I have nothing!
