Subtractor Basics - Micro Tutorial Video Lecture | Reason Tutorials: The Ultimate Guide - Video & Sound Editing

in this tutorial we'll take a look at
the original reason set the subtracter
and use it to make some nice synth
sounds from scratch sub tractor is a
virtual analog synth with a few tricks
up its sleeve
making it suitable for everything from
classics in phases and leads to
shimmering bell sounds and quirky
percussion subtractor is still a beloved
staple sent after over ten years with
all the controls logically laid out
right at the front panel it's easy to
explore and blazingly fast to go from
idea to finish sound so let's dive right
in and create a synth bass
start by resetting the device to make
sure we start with a blank slate
in subtractor the oscillators these
things right here produce the sound
we'll start with the basic sawtooth
waveform found in most analog synths
it's a great starting point for most
synthetic sounds a unique feature of the
subtractor is its phase offset
modulation basically allowing you to
subtract or multiply the waveform with a
phase offset copy of itself this allows
you to create entirely new waveforms
pretty complicated right luckily it's
significantly harder to explain than it
is to use we can simply listen and tweak
our way forward to a good sound
you
nice this signal is then fed through the
filter to shape it into something
awesome the lp next to the filter here
stands for low-pass letting the low
frequencies pass through and for a synth
bass that's just what we want if we set
it to LP 24 we get an even sharper
cutoff
[Music]
letting even less high frequencies come
through
the filter envelope changes how the
filter behaves over time so you can set
it to slowly open closed or set at what
level it will be when you hold a key
pressed
for a bass sound we want it to be quite
punchy so a short snappy decay is right
on the money
tweak the amount knob to make this
effect a bit more pronounced if we take
a look down here under velocity you can
see that the velocity that is how hard
we hit the keys affects the filter
frequency this is great for some extra
expression when playing
[Music]
they're a solid synth bass sound
if we want to take this sound further we
could utilize the second oscillator and
some modulation turning on oscillator 2
and setting it an octave lower than
oscillator 1 instantly gives us a fatter
sound now to give it all some motion we
can use the LFO LFO stands for low
frequency oscillator it's a wave form
that you can use to modulate different
things for example if I select filter
frequency as the destination here and
turn up the amount you can hear what
happens the filter frequency starts
moving will turn down the rate of the
LFO a bit and suddenly our bass sound
got a whole lot more interesting so
there you have it how to create a bass
sound from scratch with the sub tractor
