How do I connect Lemur with Windows 8?

Last Updated: Sep 22, 2014 10:02PM CEST

Lemur can connect to your computer over Wi-Fi, or with a dedicated hardware interface. Lemur supports MIDI and OSC protocols, MIDI is available on both Wi-Fi and hardware connections, while OSC is available only with Wi-Fi connections. There are pros and cons to both approaches, and this article covers all areas.
 

Wi-Fi & hardware connections


A Wi-Fi connection allows MIDI and OSC traffic and lets move around with the iPad. But Wi-Fi connections can sometimes be unreliable, depending on various configurations or general interference in the area (cell phones, other Wi-Fi devices). The advantage of a hardware connection (such as iConnect MIDI or iRig) is that it’s extremely reliable, but hardware connections only permit MIDI communication. 
 

 

Another consideration to bear in mind is that there are two ways to edit Lemur templates. You can use the built-in In App Editor, or you can use the desktop Lemur Editor application. Lemur Editor can communicate over Wi-Fi to transfer templates to the Lemur app. You can also use the File Sharing feature of iTunes, after connecting the iPad with a USB sync cable.
 

 

Wi-Fi Usage - Creating your network

 


To connect Lemur to your computer over Wi-Fi, you must connect the iPad itself to your computer, either to the same router or directly with an ad-hoc network.
 

Connecting through a router usually works fine, except that you will most likely experience a noticeably latency. Typical issues with connecting through a router is slow traffic, or blocked traffic due to firewalls. Make sure you disable the firewall, or make sure to explicitly allow ports needed by Lemur:

Connecting through an ad-hoc network is the preferred Wi-Fi connection. Many people on Windows find it easier to use a 3rd party utility such as http://connectify.me to manage ad-hoc networks. Once you have created an ad-hoc network on the computer, connect to this network from the iPad (in Settings / Wi-Fi).
 

Once you are connected, the next step is to setup MIDI ports.

 

Wi-Fi Usage - Setting up MIDI ports

You will need to have the Lemur Daemon running, as well as some 3rd party virtual MIDI ports. There are a number of different virtual MIDI ports, such as loopMIDI, loopBe and MIDI Yoke. Check them out and choose whichever suits you best. The Lemur Daemon is available as part of the Lemur Installer, a free download you can get on the Liine website:

Once you have created virtual MIDI ports, you can assign a MIDI Target in Lemur. The Lemur Daemon is very powerful, and allows up to 8 independant MIDI ports. (Each MIDI port has 16 MIDI channels, and of course on each MIDI channel you can have a full range of MIDI notes and 128 different CCs!) You can configure MIDI Targets in the Lemur Daemon or in the Lemur app itself. A typical configuration would be the following:


MIDI Target 0
Input: loopMIDI A
Output: loopMIDI B


Make sure to never use the same MIDI port for input and output, as that would create feedback.

You are now ready to send and receive MIDI messages from Lemur. Try out a factory template such as “iPad - Studio Combo”, and move the faders. Try mapping these in your favourite DAW. Once you get the hang of it, you can explore the Liine User Library or the Liine Forum to discover hundreds of Lemur templates.
 

 

 

​Hardware Connections

There are specific articles in the knowledge base for each adapter (iConnect MIDI, iRig). Search for the adapter you’re interested in for further information. Remember that a hardware adapter will only allow MIDI messages, not OSC or Lemur Editor sync.
