MU.LAB Tutorial Using Insert And Send Effects   

In music studios, you can use effects in 2 different ways: As an insert or as a send.

An insert effect is an effect that is inserted within the signal path.

Only that signal will go thru that effect.

For example, we could insert an EQ to individually tweak the signal of a single track in the composition.

A send effect is an effect where you can send a part of the signal to.

Multiple signals can each send to the send effect, so the send effect is a common effect.

For example, we could use a common reverb for multiple tracks in the composition.

Lets see how to do this in MU.LAB.

Imagine we have a sequence playing Synthia in Rack A.

If we insert an effect module directly into Rack A, then this is an insert effect because the signal in a rack flows from top to bottom.

For example, lets insert a Parametric EQ into slot 2.

Therefore click slot 2, choose MUX, and choose "Parametric EQ" from the MUX patch browser.

So now in the composition, the sequence part sends notes to Rack A.

In Rack A, slot 1 is a synth which will turn these notes into audio.

And in slot 2, the insert effect "Parametric EQ" will process the audio which comes from the synth.

Now lets setup a send effect.

Right-click at the right of the Rack Desk and choose "Add New Rack".

Lets give the new rack a proper name by double-clicking on the rack name.

Lets move the rack in between Rack D and the MASTER Rack.

Therefore click-hold on the rack name and drag the rack to the left.

Now lets insert a MuVerb into slot 1 of this new rack.

Ok, so now we have setup a new rack with a MuVerb where we can send audio to.

Now lets focus on Rack A again.

You'll see that there is a little switch at the left of the slots. This is called the Pre/Post Fader Switch. It defines at what point the signal will go thru the volume fader, cfr the docs about Racks. You can drag this switch up/down if you want.

Normally, sending an audio signal to a send effect is done 'post fader', because if we turn down the volume fader, we don't want the audio to still go to the send effect.

So lets click on slot 4, i.e. the slot just below the Pre/Post Fader Switch, and insert a "Sends -> Effect Rack".

And so here we have "Parametric EQ" as an insert effect and the "Effect Rack" with the MuVerb as a send effect.

The little knob at the right of the send in Rack A defines how much signal is send to the "Effect Rack".

You can even record automation for this knob by clicking the record button and changing the send level while recording.
