Oberheim OB-SX - Filter Freq

EDIT MODE CONTROL PANEL FUNCTIONS
The following parameters are always in the "Edit Mode". They are
used to change the sound of a program. When you choose a preset, these
controls will have no effect on the sound until they are changed. .This
way, the programs will always sound the same, regardless of the position
of the controls. When you move a control, it will affect the sound by
how much you move it, and not by its position. For instance, you could
choose program Al with the FILTER FREQ control half way up and turn
it up a quarter of the way more, and it would have the same effect as
choosing Al with the FILTER FREQ all the way down and turning it a
quarter of the way up. If it is desired to further increase or decrease
a control setting, and that control is already at its minimum or maximum
position, simply rotate the control all the way in the opposite direc
tion and then make your desired setting. To return to the preset sound,
simply re-select the program.
UNISON
PORTAMENTO
LFO RATE
QSC 2 DETUNE
FILTER FREQ
When switched on, this causes all voices to be
sounded by one key depression. In the UNISON
mode, the OB-SX keyboard operates with low note
priority, which means that the lowest note played
on the keyboard will determine the pitch of all
the voices. Pushing the button again will cause
the synthesizer to return to its Polyphonic mode.
This control determines the amount of Portamento
or "glide" between notes played on the keyboard.
This, control determines how fast bhe LOW FRE
QUENCY OSCILLATOR (LFO) oscillates. Its range
is from approximately 1/10 oscillation per second
to 20 oscillations per second. This will deter
mine the speed of Vibrato or Pulse Width Modula
tion on the instrument.
This control allows Oscillator 2 to be tuned
either flat or sharp with respect to Oscillator
1. Turning the control to the left makes Oscil
lator 2 go flat and to the right makes it go
sharp.
The associated LED turns on whenever the
second Oscillator is being detuned.
This control determines the initial cut-off fre
quency of the Filter on each voice. The Filter
is a two-pole, low-pass type.
