Guide to using Mogees on stage or within loud performances

General Support -

It is possible to use Mogees on stage and within loud environments.

 

Here are a list of steps that you can take to ensure that your Mogees is immune to interference from vibrations and feedback, in order of effectiveness.

 

Acoustically isolating your object:

Simply putting some cloth or foam underneath the object to which your Mogees is attached will ensure that on-stage vibrations, be that from speakers or other on stage instruments will be minimised.

Want to play a glass vase on stage? Put a towel underneath it to dampen the vibrations!

 

Avoid placing Mogees too close to monitors or PA speakers:

You should treat the Mogees just like any other contact microphone on stage. Try not to place them too close to speakers or monitors. If you have to be close to monitors or speakers, you may need to do some notch eq-ing to prevent problematic frequencies from feeding back.

 

Use the ‘Gate’ slider if you’re using Muon:

The Muon Sound Engine uses a lot of the raw audio from the sensor as the input to the synthesis. This means that Muon is more susceptible to feedback. By increasing the ‘Gate’ slider in advanced settings you can easily prevent feedback from occurring. Just slowly increase the slider while playing and find a level that is sensitive enough to pick up your touch, but high enough so that no humming or sustained feedback occurs.

 

Use a computer and sound card rather than an iOS device:

For serious live performances, we highly recommend using the Plugin version of Mogees rather than the iOS App. There are multiple benefits, including the quality of dedicated audio interfaces, the ability to use pre-gain on an audio interface, the ability to process the incoming and outgoing audio within a DAW, proper audio standard connectors from an audio interface to the front of house, and much much more. Plus you won’t get any calls on stage or run out of cell phone battery…

 

Manually Gate and EQ the incoming signal:

You can only really do this if you are using the Mogees plugin within a DAW. For our performances with Mogees, we tend to host the Mogees plugin within Ableton Live. If the stage is particularly loud, then we usually place a gate plugin before the Mogees plugin so that any low level sound or hum is ignored. We sometimes also use band-pass EQ’s to remove any problematic frequencies. A gate plugin with dedicated attack, release, and return level controls may be more useful than the very basic gate threshold slider within the Mogees plugin. Sometimes placing a compressor before the plugin can help limit the dynamic range and make sure that your Mogees is heard in the mix. Here is an example of a signal chain that I would use for particularly volatile stage conditions:

Use a DI Box for long cable runs:

When using a Mogees on stage with a standard unbalanced guitar cable, it is recommended that you do not use cables more than 6 metres. If there are lots of cables and electronics on stage, then longer cables will be prone to interference. Using a DI box to convert the unbalanced signal to a balanced signal is recommended for performances that require long cable runs or particularly busy setups. For larger performances using multiple Mogees on stage, we tend to use a very basic multi-channel DI box to convert the signal of the Mogees sensors from unbalanced to balanced. The additional +20dB & -20dB as well as ground lift switches can also come in very useful for setting the appropriate gain structures and removing any electrical hum.
