3-2: Filter 1

3–2b: Filter 1

Type

[Low Pass, High Pass, Band Pass, Band Reject, Dual BPF]

Selects the filter type.

When Dual BPF is selected, the “3-3: Filter 1 SUB” parameters can also be set. When you select Dual BPF, the “3-

2c: Cutoff” and “3-2e: Resonance” parameter names will change to Cutoff A and Resonance A respectively.

Filter Types and Cutoff Frequency

Low Pass Filter (LPF)

frequency

A low pass filter is the most commonly-used type of filter, and passes the range of frequencies that lie below the cutoff frequency, and cuts the high range. Cutting the higher

Band Reject Filter (BRF) A band reject filter cuts only the range in the vicinity of the cutoff frequency, and passes the rest of the sound. This type of filter

frequency gives a unique character to the

sound.

High Pass Filter (HPF )

frequency

A high pass filter passes the range of frequencies that lie above the cutoff frequency, and cuts the low range. This type of filter is used when you wish to make the sound thinner. However, raising the cutoff frequency

Dual Band Pass Filter (Dual BPF)

The dual band pass filter places two band pass filters in parallel. It allows you to simulate sounds

frequency

Cutoff Frequency

A band pass filter passes the range of frequencies in the vicinity of the cutoff frequency, and cuts the ranges above and below. This type of filter is used when you wish to emphasize a particular portion of the sound.

Frequency A Frequency B

Input Trim

[0…99]

Specifies the level of the input to filter 1.

If this value is raised, the sound may become distorted if the resonance setting is high, etc.

3–2c: Cutoff/Cutoff A (Cutoff Frequency)

Frequency

[0…99]

Specifies the cutoff frequency of filter 1. As this value is increased, the cutoff frequency will rise.

Since the BPF and Dual BPF filter types use filters with differing characteristics, their actual cutoff frequency may differ even if their settings are identical.

EG (Cutoff Frequency Modulation EG)

[EG1…EG4, Amp EG]

Selects the EG that will create time-varying change in the cutoff frequency of filter 1.

Intensity (Cutoff Frequency Mod. EG Intensity)

[–99…+99]

Specifies the depth and direction of the control that “EG (Cutoff Frequency Modulation EG)” will have on the cutoff frequency. With positive (+) settings of this parameter, the tone will become brighter when the various EG levels rise into the + area (the setting of the “Frequency” will be reached when the EG levels are at 0), and darker when the EG levels fall into the area. With negative (–) settings of this parameter, the tonal change will take place in the opposite direction.

AMS.1 (Alternate Modulation Source 1)

[OFF…MIDI (CC#83)]

Selects a modulation source 1 (page 64 of this manual) that will control “Frequency.”

Intensity (Cutoff Frequency AMS.1 Intensity)

[–99…+99]

Specifies the depth and direction of the effect that “AMS.1” will have on the cutoff frequency.

AMS.2 (Alternate Modulation Source 2)

[OFF…MIDI (CC#83)]

Selects a modulation source 2 (page 64 of this manual) that will control “Frequency.”

Intensity (Cutoff Frequency AMS.2 Intensity)

[–99…+99]

Specifies the depth and direction of the effect that “AMS.2” will have on the cutoff frequency.

Synthesizer specifications

Korg synthesizers have established themselves as a powerhouse in the music production landscape, combining cutting-edge technology with user-friendly features to cater to musicians, producers, and sound designers alike. These iconic instruments have continuously evolved since the company’s inception in 1963, embodying innovation and quality.

One of the defining features of Korg synthesizers is their diverse range of models which cater to different musical styles and needs. From the grand M1 synthesizer that popularized MIDI in the late 1980s to the more recent Minilogue and Prologue, each model presents unique capabilities. The Minilogue offers a straightforward interface and powerful four-voice polyphony, ideal for both novices and seasoned musicians. In contrast, the Prologue, with its advanced circuitry and multi-engine technology, provides extensive sound design possibilities.

Korg synthesizers are known for their rich sound engines. Many models utilize the proprietary EDS (Enhanced Definition Synthesis) technology, which delivers detailed and dynamic sounds. Users can expect a broad sonic palette, facilitating everything from lush pads to biting leads. The multi-engine architecture found in the Prologue adds another layer of versatility, allowing for the integration of wavetable and FM synthesis alongside traditional analog sounds.

Another key characteristic of Korg synthesizers is their connectivity options. Most models are equipped with MIDI, USB, and audio outputs, making them easy to integrate into any studio setup or live performance rig. The ability to control virtual instruments and external devices through MIDI enhances the functionality of Korg synthesizers, enabling seamless integration into modern production environments.

Korg emphasizes portability with many of its synthesizers. The compact design of products like the Volca series allows musicians to create music on the go, making them ideal for traveling artists. Each Volca unit houses powerful synthesis technology within a small footprint, ensuring that users don’t sacrifice quality for convenience.

Korg also recognizes the importance of community and education in music production. The company frequently updates its synthesizers with new patches, features, and sound libraries, empowering users to keep their sounds fresh and relevant. Additionally, Korg offers various online resources, tutorials, and forums to support their users in exploring the full potential of their synthesizers.

Overall, Korg synthesizers encapsulate a balance of tradition and innovation. With their rich sound engines, user-friendly interfaces, and extensive connectivity options, they remain a favorite among musicians and producers seeking to push the boundaries of their sound. As technology progresses, Korg continues to set new standards in the world of synthesizers, inspiring creativity and musical exploration.
