Korg Synthesiser Buying Guide

Korg is a Japanese manufacturer of electronic musical instruments and equipment, including electronic synthesisers.

About Korg Synthesisers

Synthesisers are electronic musical instruments. They have different types of user interface, typically a keyboard or other instrument controller. Other types of audio controller known as sound modules are also commonly used, often using Musical Instrument Digital Interface (MIDI) links.
The sounds produced can be either imitations of other instruments or new sounds. Sound is produced by the generation of electrical signals that are then converted into sound by amplifiers and loudspeakers.

Types of Synthesis

The various types of synthesis include additive synthesis, subtractive synthesis and ring modulation. Each type creates distinctive types of sound by generating and modulating sound waves in various ways. The use of synthesisers in popular music led to the development of the synthpop music genre in the late 1970s and throughout the 1980s and beyond.

Digital or Analogue

Synthesisers may be either analogue or digital, with analogue the original type and most frequently used. The components of synthesisers include electronic oscillators, which generate the raw sound signal, filters that modulate it and amplifiers that boost it. Synthesisers also contain envelopes to shape the sound as well as other modulating and effects processing components.
Korg has manufactured synthesisers since the early 1970s, producing products aimed at both amateur and professional musicians. Today the product range includes a variety of synthesisers, mostly with keyboard controllers. The expertise that Korg brings to synthesiser manufacture has resulted in products that are high quality, portable and capable of delivering high performance, superb sound.

Choosing a Korg Synthesiser

Considerations when it comes to purchasing a Korg synthesiser include the type of synthesiser, functionality with regards to significant features and different types of effect available.

Type of Synthesiser and Features

Most of Korg’s synthesisers are analogue synthesisers with a keyboard controller. Features to look out for include the number of sounds, capabilities for sound combination, number of different effects, panel layout, editing software, connectivity and keyboard features such as the number of notes and key sensitivity.
Synthesisers range in size and complexity, from portable mini synthesisers with compact features to large analogue synthesisers with incredible functionality and 61 note keyboards.

Sounds and Effects

Part of the appeal of synthesisers is the access to hundreds of different sounds, including a variety of piano sounds, strings, guitar, wind, brass, and synth sounds. Some Korg synthesisers have over 500 different high-quality sounds. These sounds may also be combined to create new and innovative complex arrangements. A synthesiser with a decent effects system will negate the need for an external effects processor, so it is worth checking this out both from a cost and convenience perspective.
Korg synthesisers also offer the ability to insert different effects into the track, such as equalisation (EQ), delay, reverb, chorus, phaser, and flanger, allowing the sound to be modulated, customised and synchronised as required. Synthesisers may also be able to process external effects and add vocal characters. Vocoders are used to reproduce vocals and speech, which can then be added to sounds.

Panel Layout

The design of the panel affects how user friendly and intuitive the controls are and, therefore, how easy and enjoyable the synthesiser is to play. Panel layout varies in complexity depending on the type of synthesiser and number of functions and features. Features such as LED lights and indicators can be a nice touch.

Keyboard Features

Keyboard features to consider include the number of notes and key sensitivity. Some Korg synthesisers have 61 note keyboards running from C to C over five octaves. This length is more than sufficient for most purposes, although pianists may prefer a longer keyboard.
When it comes to how the keys feel to play, this can be a matter of individual taste and preference, so try out an instrument if possible before purchasing.
The keyboards on synthesisers respond quite differently to piano keys to touch. Piano keys generate louder sounds depending on how hard they are struck, a characteristic known as velocity sensitivity or touch sensitivity. Keyboard keys have a different construction and mechanism for generating sound. Most keyboard synthesisers are able to imitate the effect of piano keys to an extent, by generating louder sounds with stronger playing. This feature of keyboards allows for more natural and expressive playing. Always check to see if the keys are velocity sensitive or touch sensitive if this is an important consideration.
Keys may also have a characteristic known as aftertouch. This is which continued pressure on the keys encourages sound to be modulated after being generated. Aftertouch is another way to inject expressiveness and creativity into playing, but it is not typically considered as important a feature as touch sensitivity.
