iEQ Pro is an iPhone App which has the following features:

  1. Audio Analyser having Oscilloscope, FFT, Sonogram and 1/3 Octave RTA Bargraph views.
  2. 31 band Graphic EQ which can control the EQ Racks in the LS9, M7CL and CLx series of consoles, or can also control a group of Behringer DEQ2496 EQs via MIDI over WiFi

A typical setup is shown below:

The hardware/software requirements are as follows:

Hardware: iPhone 3GS or later, iPad, Mac or PC with WiFi and USB, Console with latest firmware.

Installing and using UMMU Server:

 
 


Firstly, download UMMU Server for Mac or Windows http://www.strongsoft.co.uk

Unzip the UMMU Server App, and place it in your Applications Folder (Mac) or your Programs Folder (PC). UMMU Server must be launched first, then the iEQ Pro App (on the iOS Device).

When the UMMU Server is launched, you will see the following window (MacOSX pictured, using MIDI Interface):

UMMU Server

Once this window is visible, you should be able to set your MIDI routings using the pull-down menus - once
you've done this, you're ready to go!

Using iEQ Pro when there's no WiFi network Available:

To do this you must create a computer to computer network (P2P):

For PC: Google 'Setting up a P2P Network on your PC.

For Mac:

In the Airport menu (see below), click on 'Create Network':-

 

Airport Menu

In the dialogue box that appears, type a name for your P2P network (anything will do!)

 

P2P Dialogue Box

The airport icon will change to the P2P icon (see below):-

 

P2P Network Created

You can now connect to this network from your iPhone in 'Settings' > 'Wi-Fi'. Just select your P2P nework name from the list.

 

iPhone > Settings > Wi-Fi Menu

Finally set your UMMU Server SEND IP settings to the IP address of your iOS device:

iPhone > Settings > IP Address

Setting up the Console:

 
 

 

Make sure you have the latest version of the Yamaha Console Network MIDI Driver installed on your host computer. You can download it from:

Or alternatively, you can use a MIDI interface, or the UMMU Box (you don't need a host computer with UMMU Box).

http://www.yamahaproaudio.com/downloads/firm_soft/index.html

Then configure the Console Network and MIDI settings in a fashion similar to the screenshots below (LS9 pictured). If you don't want to use Yamaha Studio Manager, set that box to '-'.

LS9 MIDI Settings

Note that if you are using UMMU Box, you will need to select 'MIDI in the 'Rx Port' and Tx Port menus.

Your Device should now be receiving MIDI from your iPhone with iEQ Pro running on it.

The Sonogram shows a view of sound energy over time, the frequency is represented by the y-axis, time by the x-axis, and the energy by the colour of the trace (red = loud, blue = quiet).

The RTA/GEQ View

 
 

 

RTA/GEQ View

 

RTA/GEQ Fader Zoom

 

 

This view shows a 31 band 1/3 octave bargraph display, and a 31 band graphic EQ. It is accessed by pressing the 'RTA/GEQ' button. The peak hold values (red bars), and mean value (yellow line) can be reset at an time by touching in the waveform display.

The GEQ is divided into four parts. touching on a part brings up a 'zoom' fader view of that part, allowing you to manipulate the faders. Touch again inside the blue outline to return to the fader overview.

Touch and hold a part (for 1 second) to return the GEQ settings to 'Flat', both in the App and on the selected device.

To equalise a room, simply feed pink noise through the sound system, allow the peak holds and mean level to settle down (5-10 seconds), then press the 'Auto EQ' button.
The GEQ self-adjusts to the required settings to compensate for the shortfalls of the room in the frequency domain. These values are sent out via MIDI over WiFi to whichever GEQ you have connected.
