Using mio MIDI Management to Optimize Your Rig

The factory setup for your mio2 connects “everything to everything,” so you can quickly get

gear connected, use your controllers, and listen to your sounds.

Once you have your gear connected and working, and you’ve become familiar with the mio2’s

MIDI management features, we recommend you spend some time tweaking your settings to

improve efficiency, minimize latency, and avoid potential data loss.

Here are some recommended guidelines for optimizing your setup, to be done in the order

shown. Don’t forget to save your new configuration to the mio2 for next power-up:

1. Disable MIDI outputs for controllers that only send MIDI data.

If you have a MIDI controller connected to one of the DIN ports and that controller doesn’t need to receive

MIDI data (it may not even have a MIDI input jack), you should disable that DIN output. Or if any of the DIN

output jacks are not connected to anything, you should disable those DIN outputs. The easiest way to do

this is to go to the MIDI Info Page in iConfig and uncheck the “output enable” box. This will prevent any MIDI

events from being sent to those ports.

2. Disable MIDI inputs for controllers that only receive MIDI data.

Perhaps you have a sound module that never sends MIDI data, or a sound module that sends MIDI data that

you don’t need. It’s best to remove that module as a source of MIDI data. You could do this by removing the

MIDI cable that connects the DIN input jack on mio2 to the sound module’s DIN output jack. Another way to

do this is to go to the MIDI Info Page in iConfig and uncheck the “input enable” box.

3. Remove MIDI routes that are not necessary.

As we said earlier, the default factory routing connects “everything to everything” to help you get started.

You can improve efficiency by trimming this down so that connections are only made from sources to

destinations that require it. You may have a sound module that you only want to connect to your Mac for

DAW playback and to one of your MIDI controllers for entering note data. The default routing may have that

sound module receiving MIDI data from all other ports. Disconnect all the routes that you don’t absolutely

need (see MIDI Port Routing Page).

4. Enable filters.

There are many kinds of MIDI data. Some of them you may need in your setup but some you may not. The

factory default filters out active sense messages, but all other MIDI data types are enabled. You may have a

controller that is sending out after touch messages whenever you press on the keyboard, or is sending out

sysex messages whenever you touch something on the front panel, or is sending out MIDI clock messages all

the time. If those messages aren’t required by something else in your setup, then filter them out at the

source by adding a filter to the MIDI input (see MIDI Port Filters Page). Similarly, if you have a MIDI sound

module that is receiving after touch messages or MIDI clock messages or sysex messages but isn’t using

them, then add a filter to the MIDI output. Enabling filters can greatly reduce the amount of unnecessary

MIDI data clogging the system.
