Tutorial 2: Making a Melody

We're going to turn the drone from the last tutorial into a melodic sequence.
1) Start with the drone from Tutorial 1.
2) Find the LFO->VCA button (the top small button on the left side of the module) and tap it.
3) Change just one note in the sequence. Hold down any of the buttons on the top row while

The notes should start playing one after another (rather than all notes playing constantly).
Each slider will flash when its channel plays its assigned note.
you turn the Transpose knob. Can you hear how just one of the notes goes up or down in
pitch? If you watch the light ring you'll see just one of the lights move up and down (the
light has the same color as the button you're pressing). Try transposing another channel.
You can tune all six channels this way to make any melody you want! Note: The
Transpose feature defaults to 12-notes per octave quantization. If you hold down the Fine
button while turning Transpose you can adjust the pitch by micro-tonal amounts.

one channel. Hold down one of the
buttons on the top row and turn the
Browse knob. Do this for each channel,
finding a timbre you like.

the LFO Speed or Shape of just one
channel at at time!
In the last tutorial, we held down a Channel button while turning a knob
(Transpose and Browse) to change the pitch and waveshape of one channel at
a time.
This technique works across almost every feature of the SWN. For example, try
holding down a Channel button while turning the Octave knob — just that
channel will go up or down by octaves. If you just turn the Octave knob by itself,
all of the channels will go up or down in octaves.
In Tutorial 2, we pressed the LFO->VCA button to make the channels fade on
and off instead of being constantly on. If you hold down a Channel Button while
tapping the LFO->VCA button, just that channel will change.
Keep this technique in mind as you play with the SWN.
What's an LFO?... and a VCA?
An LFO is an oscillator that goes up and
down repeatedly at a relatively slow tempo.
You can visualize the LFOs on the SWN by
watching the row of six lights in the center
of the module; they get brighter and
dimmer as the LFOs go up and down.
Usually an LFO is set up to make some
quality of the sound go up and down
(besides just a light)! In our tutorial we're
using the LFOs to make the volume of each
channel go up and down: this makes each
channel sound like it's playing a note.
A VCA (Voltage-Controlled Amplifier)
connects the LFO's up and down motion to
the loudness (or amplitude) of the sound
produced.
