Create and connect to a MIDI Network Session (mac)


On your iPhone:

  • Connect your iPhone or iPod touch to your chosen WiFi network (either ad hoc or router-based). If your router is not connected to the internet see here.


  • Launch or switch to the Motion Synth App.


On your Mac:

  • Locate and launch the Audio MIDI Setup application (in Utilities). You may want to place a shortcut to this application in a convenient location for future use.

  • IMPORTANT: If Audio MIDI Setup was already running when you connected your iPhone/iPod to the WiFi network it is CRITICAL that you quit and relaunch Audio MIDI Setup prior to attempting the following steps.
  • After launching Audio MIDI Setup you want to access the MIDI Network Setup window.

  • If the MIDI Network Setup is not visible, go to Audio MIDI Setup > Window > Show MIDI Window (also called MIDI Studio in newer versions of Mac OS).

  • Within MIDI Studio, double-click on the Network button to open the MIDI Network Setup window.

  • In the My Sessions list at the top left, press the + button create a new session. The default name for the session is Session 1. Activate the session by ticking its checkbox.

  • In the Directory list, select the name of your iPhone/iPod touch and click Connect.
  • To test your connection, try triggering some notes from the Key Screen in the Motion Synth App.
    • Successfully received notes will elicit red bars in the latency scale (bottom right hand side of MIDI Network Setup window).
    • If you have setup the Motion Synth App to send MIDI CC messages in response to motion, making the selected motion should also elicit red bars.
  • Once established, the connection should be very stable.
    • In our testing the connection remains usable for many hours at a time.
    • If your connection is not stable or has high latency you may be encountering radio frequency interference (see below).

Troubleshooting

  1. If you can see your device in the Directory but cannot produce a connection, try quitting Audio MIDI Setup completely (shorcut: COMMAND Q), relaunching Audio MIDI Setup, then re-attempt connecting.
  2. If a connection still has not succeeded, try restarting your macbook and iPhone/iPod touch and then proceed through the above steps again.
    1. Some users report that a reboot step is necessary when connecting a new iPhone/iPod touch for the first time, but after the first successful connection the reboot step is no longer necessary.
  3. If these troubleshooting steps above do not solve the issue please follow the troubleshooting checklist guidelines.

Router not connected to internet

You may chose to use your router to connect the Motion Synth to your laptop without any internet connection at all. If your router is not connected to the internet you may get iOS prompts to login to an internet service provider. You can prevent these prompts by, within the iOS WiFi menu, tapping the 'i' symbol to the right of your network and ensuring that the auto login button is off.


WARNING! WiFi interference in live venues

Ad hoc networks between laptops and iOS devices can get 'drowned-out' by mobile phone signals in live venues. The bigger the crowd the bigger this problem becomes.

In this scenario it is better to use a MIDI cable (eg iRig MIDI) from your iOS device to the MIDI target, or set up a special wifi router that can isolate your signals from the crowd, and is connected to your laptop via ethernet.
