Transpose Cv Jack; Spread; Octave - 4ms Company Spherical Wavetable Navigator User Manual

Transpose CV Jack

Applying CV to the Transpose CV jack will shift the frequency of all six oscillators by the
same amount. The jack responds to CV between 0V to +10V; since Transpose has a 1V/oct
response curve, its range is ten octaves. The resulting frequency is not quantized by default.
However, any channel that has a Scale selected will be quantized. The Transpose jack
responds to any CV signal from DC (0Hz) to 20kHz, but the FM effects are more diverse
below 1kHz.
There are many uses for the Transpose jack, including:

Spread

Pushing and turning the Transpose/Spread knob selects a pattern of transposition amounts
which are applied to the channels. This creates a chord, and there are 26 chords (also known
as spread patterns). As you push and turn the Spread knob, the light ring displays how the
pitches spread out in the same manner as when the Transpose knob is turned. Any
transposition manually assigned to channels by turning the Transpose knob or Octave knob
Spread
will be added to the selected spread pattern. Also, any Scale that's assigned to a channel will
limit which notes can be assigned to the channel.
The first spread pattern has no transposition for any channels. This the default pattern that's
loaded when you first turn the module on. The next spread pattern raises channels C and D
by a fifth. The third pattern then lowers channels E and F by a fourth (i.e. five semitones),
resulting in a fifth with inversion. The patterns continue in a series listed below:
If you transpose one of the channels using the Transpose or Octave knobs, then that offset
will be added to the selected spread pattern.
The Spread CV jack offsets the selected pattern when CV is received. The jack responds to
CV in the range from 0V to +5V. Patching an LFO or sequencer into the Spread CV jack will
cycle through chords.

Octave

Turning the Octave knob will change the pitch of the channels up or down by octaves.
Holding down a Channel button while turning the Octave knob will change just that channel.
Octave
The SWN has a 15 octave range which extends beyond the limits of human hearing and the
audio hardware of the SWN. This creates aliasing when the upper octaves (green) are
selected (which is useful for creating new timbres and textures).
Scale
• Transposing a melody or chord on all six channels using an external keyboard,
sequencer, or stair-step waveform.
• Using an LFO (internal of external) to provide vibrato on all channels.
• Creating rich harmonics with FM effects.
• Triggering channels in Note Mode to play notes whenever the CV signal changes.

2-4: Fifths
5-7: Major thirds
8-10: Minor thirds
11-13: Major sixths
14-16: Major sevenths
Octave Display
The light ring will display the current octave for each channel from lowest (lower left) to
highest (upper right). The color of each channel's button will also display its octave,
with red being the lowest octave, yellow being the middle octaves, and green being
the upper octaves.
