Controls And Connectors; The Front Panel - Oberheim OB 12 Operating Manual

OB 12
1. LFO 1 section
This section of the front panel contains the controls relating to the LFO 1 (Low Frequency Oscillator
1). The LFO 1 is the first low frequency oscillator in the generation chain, capable of generating
a waveform which modulates the sound cyclically.
2. OSCILLATOR COMMON section
Here you will find the controls for the common settings of the OSCILLATOR 1 and OSCILLATOR
2 sections. These controls allow you to set the envelope of the oscillators and their balancing
(since they are able to generate two different waveforms) to control the tuning of the sound.
3. OSCILLATOR 1 section
These controls allow you to set the characteristics of the first oscillator for generation of the first
basic waveform (which however, will already be complex) of the sound you are about to create.
4. OSC 1 PARAM (Oscillator 1 Parameter) section
This section describes the functions of the [WAVE CTRL] control knob in the OSCILLATOR 1
section.
5. OSCILLATOR 2 section
As for the OSC 1 section, here you can set the characteristics of the second waveform which is
the basis of the sound generated by the second oscillator.
6. FILTERS section
This section contains the controls relating to the characteristics (envelope, cut-off frequency and
resonance, to name the most significant) of the filter, i.e. the combination of FILTER 1 and FILTER
2, by means of which you can modify the brightness of the sound over time.
7. AMPLIFIER section
Here you can set the characteristics of the amplifier used to regulate the level of the sound over
time.
