Logic Pro X - Create a Master Filter Bus for a Transition Effect Video Lecture | Logic Pro X: A Practical Hands-on Course - Music

hello this is music tech help guy
welcome to this video tutorial in Logic
Pro 10 on how to create a main filter
bus or a master filter bus the point of
doing something like this is to be able
to take every single instrument in your
song and filter it down with a low-pass
filter so maybe you want to cut out the
highs and just here the lows or maybe a
high-pass filter you want to do the
opposite maybe you want to get rid of
the lows a certain point in your song
and just leave the highs or maybe cut
out the lows and the highs and just have
a middle band of frequencies but only
temporarily apply that effect that's
what we're going to do in this video a
perfect example of this is Coldplay's
adventure of a lifetime if you haven't
heard the song go check it out in
youtube or on itunes
there's a section between the the end of
the verse and the beginning of the
chorus where he says feel my heart
beating and he's basically taking those
words and converting them well basically
making a musical idea out of his words
so basically what happens at the end of
the the verse is the whole song sort of
gets filtered down just to the sub
frequencies like a thousand Hertz in
below and so you hear just sort of like
the sub of the kick and the sub in in
all of the instruments but you don't
hear any of the highs and as soon as the
chorus kicks in all the high end kicks
back in the problem with trying to do
this say like you know you could just do
this like on your master buss you can go
straight to your master fader and throw
throw like an EQ and a filter on the
master buss and automate that the
problem with that is that you don't want
the vocals to be filtered that way you
just want the music to be filtered that
way so what we're going to do is we're
gonna take all of our instruments in our
mix and we're going to create a
essentially an aux track and we are
going to put a filter on that track and
automate that filter down just at the
point where we want it filtered out and
then filter it turn off the filter as
soon as the chorus kicks in so I'm
actually working with a client of mine
to
create a remix of the song adventure of
a lifetime right now so this is just a
little a little snippet from that remix
it's it actually going to be end up
being an instrumental remix but
basically I have the whole backing track
here so let me just play a little bit of
this and then I'll explain what we're
going to do
all right so everything over here is the
tail end of the verse everything over
here is the beginning of the chorus so
this little section in between is sort
of like a transitional it's like a
transition between the verse and the
chorus so what I'm going to do is in my
mixer I'm going to make every single
instrument that's going to the stereo
output the master output and I'm going
to select all of those and I'm actually
going to send them to a bus instead so
I'm going to click on the output tab go
to bus and choose a an empty bus so I'll
choose bus for now some of my
instruments like my guitars here are
already going to a bus they're already
going to bus 3 which is essentially like
a guitar bus so what I'm going to do is
those things I'm going to leave those
alone but I will send those buses
because I have a guitar delay track a
guitar bus those aux tracks as well as
these last two instrument tracks in the
end here these will also go to bus 4 so
say buffs for there we go why I have a
buss 5 here I don't know I'm going to
delete that there we go
and one of the cool things about logic
is it automatically when you create a
bus on an output or a bus on a send it
actually automatically creates an aux
track for you with that bus assignment
so here's our this is going to be our
filter bus so I'm just going to call
this filter bus and we're going to do is
we're going to put an EQ on this an EQ
that has a filter in it you could easily
use the channel EQ and logic or the
linear phase EQ and logic I'm actually
going to use the H EQ from waves'
it's one of my my favorite eq's and so
everything in the session is running
through this filter bus before we hit
the stereo output now why not again like
I said before why not just put the the H
EQ on the master output and then you
know and just filter everything well
when we record another instrument in
this or another vocal in this if there's
something that I don't want filtered I'm
not going to send it to the filter bus
I'm going to intentionally bypass that
filter bus so in our case everything
in the backing track is going to be
filtered while while the vocal or the
main instrument it will not be filtered
now I could if I really want to I could
just just choose the instruments that
are actually present here in the in the
transition but who knows how many
instruments you have in your song if
you're trying to recreate this effect in
your own composition maybe all of your
instruments are in there so that's just
why I'm doing it on everything and not
just you know these six instruments or
five and df6 instruments that are
actually in the transition there's also
like reverb tails and effects effects
tails off the end of some of these
instruments that I also want filtered
okay so here's what we going to do I'm
going to go into my go back to my mixer
for a second here I'm going to right
click on this track and I'm going to
choose create track and what this is
going to do is it's going to create a an
actual track out in my session for our
filter bus so we put that at the top we
pull it up or zoom it in a little bit
and in the original song let me just
listen this one more time
yeah the original song somewhere right
around measure 37 maybe slightly before
37 the filter kicks in slowly ramps down
you hear just low frequencies here and
then right when the the two crash
cymbals come into Dada right here like
halfway through measure 41 the filter
kicks back in so that's we're going to
do we're going to hit a to bring up
automation on our filter bus and we're
going to choose the specific element of
H EQ that we want to automate so I'm
going to turn off all these other bands
not that you have to do this I just have
it I could do it
turn on the low-pass filter I'm going to
roll the low-pass filter all the way up
to its highest frequency I'm going to
choose a different circuit something
that's just something that doesn't cut
out so much very let's get move the
digital circuit and roll the cue up so
really we're cutting we're cutting high
frequencies on this track just in the
highest most at the highest most point
we really shouldn't be able to really
hear that and the high the highest most
frequency in H EQ is over 20,000 anyway
so so we're going to do is we are going
to choose H EQ and if you're using you
know the channel EQ or the linear phase
EQ this will show up here and I'm going
to choose the low-pass filter so it
should show up as L P here it is
low-pass filter frequency and at measure
37 I'm going to draw in some automation
I'm going to pull this down to about
just under a thousand 931 that sounds
good and then right where that those two
little crash cymbals kick in halfway
through measure 41 I'm going to kick the
the filter out very quickly - it's going
to be right at and by the way one thing
you can do there here that really helps
is change your snap mode to like beat
and then make sure that your
snap automation is on because then any
automation points that you create will
actually snap to the grid so I want this
one to snap right to the grid there I'm
going to create a point I'm going to
turn this on division mode create a
point there and then another thing we
can actually do just to make this a
little easier so we've got like our like
five points here if I pull this down in
the middle here it pulls down both sides
so that makes a little bit easier so
let's go just under under a thousand I'm
going to pull this one over I'm going to
pull this out I'll pull this over here
we go so let's see what this sounds like
it sounds cool but it sounds a little
abrupt right at the end here what I'm
going to do is I'm actually going to
sort of roll this in a little bit slower
make it sort of like a ramp up sort of
like an effect let's see if that sounds
like now yeah that sounds pretty good
let me just adjust we're keep hitting
the wrong key there let me just adjust
where I I have that I'm going to pull
this up a little bit I'm gonna pull this
up to like there damnit I keep hitting
the wrong key alright so I like the way
that sounds but one one little issue
here is because we're sending all of our
tracks into this filter bus you can see
that we are clipping a little bit it's
it's evident in the plug-in to that
we're clipping so one of the things I'm
going to do is I would actually pull the
input level of the EQ down a bit just to
prevent those clips so we really don't
want our bus to clip and if we want
extra volume you know for if we lose two
DB on our on our filter bus it's fine we
can make up for that on the master fader
so this will sort us one more time and
see what it sounds like
and there we go that's using a an ox
track and logic to create a filter bus
for your filtered instruments so I hope
you guys enjoyed this video and thanks
