The
SYNC
switch locks the pitch of Oscillator 2 to follow the pitch of
Oscillator 1 in hard synchronization, so OSC 2 will tune only to the
harmonic frequencies of Oscillator 1. Intermediate frequencies of Oscillator
2 will produce unusual, “metallic” wave shapes and timbres; both
Oscillators sharing the same base frequency makes all of this possible.
The
SUB LEVEL
switch selects a half or full volume octave down Sine Wave
with a center off position––a common feature of the Boomstar enabling
quick escapes from more complex programming settings.
The
WAVE MIX
switch selects single waveform settings or blending
combinations of Triangle or Saw with Sine or Pulse/Square waveforms;
center off position switches make it easy.
The
PULSE WIDTH
knob sets the width of the Square waveform: wide, square
rectangular forms to narrow, nasally-tall, skyscraper/cityscape-like shapes.
A classic Square Wave dials in at the 12 o’clock knob setting––for that
wonderfully warm and yet hollow, pulsing, rubbery “clarinetish” tone.
4.2.3 VCO 2 - Voltage Controlled Oscillator 2
The
TRACK
switch
selects Oscillator 2’s
pitch tracking
capability. The
ON
position is the
“business as usual,” 1
volt per octave default setting; the
OFF
position “disconnects” the pitch
control of the keyboard, so a fixed or static pitch can be achieved, which is
expressive for a variety of uses, i.e., as a fixed value low frequency
modulator when the
LO
setting is employed, an inflexible “flanged”
“phasey” synced Oscillator timbre effect, a drone/“bagpipe” song key
