I cannot connect my iPad to my local network anymore. My local network is not connected to the internet. I read that with iOS 6 every wifi connection must contact the Apple server. Does that mean that offline wifi connections are no more possible?
EDIT: whoops, was using rtp, not loop... loool... nyway, seems fine... ;) weeee=)
(seems i also need to manually set the ports in the daemon now.. but it works=)))
hi=)

yeah, also here..

iphone ios5 = connects fine

ipad ios6 = rtpmidi sees the ipad but i cannot connect the session... (latency ????)

the ipad was fine under ios5...

(windows+ipad)

Does it work for you under windows and ios6?

thx=)
no. The iPads are visible, and networks are visible, you can even connect, but without any effect. The network symbol on the iPad is off.

Connecting to a router with internet access is no problem. But connecting to an ad-hoc network is not working, even with enabled internet sharing. I hope there will be a solution, but so far I haven't seen one.
I'm having the same issue.

Lemur also doesn't send MIDI data on any channel except for Omni/ 0. Tried this with both Magellan and Animoog, neither work with any other channel but 0. Anyone else experience this?

Yes having the exact same issue. Have emailed Liine support already - however, i did manage to get it working.

You need to setup the network as you did before, and although the little signal fan is not working, have faith that it is actually connecting, may take several attempts of doing the same thing...

Then, open the lemur app, then normally when you can choose the midi ports from the drop down menu you'll realise the MIDI targets are no longer an option, it'll only say the name of your ipad and session 1 below it.

So, you have to keep the lemur App open and go to Lemur Daemon, You'll then notice that nothing appears automatically like before, so you have to select 'Add' then expand the Daeom Midi In and Out menu's and double click on the midi Input and then your iPad should appear 'eventually' as a recognised destination for port complete with the IP address in brackets, and then you have to expand that. And do the same for both Midi in and Out- then back on the lemur app itself the drop down menu's we're used to will appear again...

This happened to me 5 mins before a DJ set last week and i thought i was screwed, and i repeated the above about 3 or 4 times, then suddenly the iPad appeared but only when adding manually...and as you mentioned, works perfectly on the home wireless network, but this strange occorance is only when creating an ad hoc personal network - but the above steps shold get it working again - for now!

Hope this works!
Glad you found a workaround. I will try those steps again, maybe it works this time. I just have two questions, to rule out some questions: do you have WEP or WPA as security option in your ad-hoc network? Or do you use a router?
The Ad-hoc network is literally a 'computer to computer' network created from the drop down options when you click on the signal fan on the mac and go to 'create Network...' - and i never use a security option. so no this one wouldn't go through the router.

It seems if you use the home network through the router e.g., BT lets say, this error doesn't seem to be an issue, it will connect like before.

that's what I think, too. I believe it has to do with the wireless card, ad-hoc type, or something we don't know yet.
I reported this to apple as well, because normally when you're connected to a network you create, it would still have that signal fan thing going, it only puts a tick next to it on the ipad...let's see i guess.
UPDATE re iOS6.

Lemur 3.2.2 has been submitted to Apple with fix's for iOS 6, WiFi connection etc.
Once it is approved (not sure on exact timeframe) it will be available via iTunes.
And I will post it's availability here as soon as I know.

Thanks for the various reports and support in sorting out this problem.

I think it is all about setting the correct static IP address and subnet mask. All devices should have the same numbers in the first three fields (maybe only in the first two):

IP: aaa.bbb.c.x
subnet: 255.255.255.0

where x is different on each device/computer.

With this rule I have no problems anymore using a router or ad-hoc, and iOS 6.0.1, and Windows machines. Earlier (iOS 5) I did it all wrong it seems, using totally different IP addresses, but iOS 5 was more 'tolerant' and I was believing it had to be like this. It worked well until iOS 6, so I was confident to have the correct settings. I remember that in the beginning (early 2012) I did it almost right as described above (it's a logical step actually), but it wasn't working for some other reason that I can't quite remember. Maybe because I used Connectify, maybe because of old firmware for the wifi card, maybe because of 255.255.0.0 for the subnet, I don't know. I read one had to use 255.255.0.0 and not 255.255.255.0, so I did not change that for months.

It's also possible that the settings may be correct, but you just need to reboot iPad/computer or reset the network settings on the iPad. That lead me (and many others) to a wrong trace, repeating the same mistakes again and again, thinking they must be right.

Reading about other people's connection problems did quite often add to the confusion. The blind leading the blind. :roll:

Now I think, after about 11 months experience with wireless networks, I can be really confident and setup any kind of wireless connection to Windows and Mac machines and routers in short time, without having to experiment or go in a wrong direction. I also learned that MIDI clock syncing is only usable with wired MIDI connections.

I enjoy this very much, and concentrate on finishing templates and of course doing music sessions almost every day.
I think the whole thing is also wifi-card dependent.

I set up Lemur first in my gig-laptop. Followed the tips found on the forums, made static IPs (192.168.10.1-laptop, 192.168.10.2-iPad) and used 255.255.255.0 subnet. Also enabled WEP protection. Results - works like a charm, always, no hickups, no latency, perfect!

I did the exact same settings on my PC which has a no-name-no-brand USB wifi adapter - I used to have an ethernet cable on that, but I bought this wifi thingie just to be able to connect with Lemur and work on my projects. Guess what? The conectivity is poor, it keeps getting disconnected and frankly, if the behaviour of my PC-Lemur connection was my first expererience with the app, I would be very very dissapointed (and frustrated).
Some gigs are coming up so I dont have the time to troubleshoot but after those I will look into it. The only difference between the two machines (besides the wifi card) is laptop OS is Win 7 64bit while PC OS is Win 7 32bit.
