Quick Answer

Virtual instruments are software programs that generate sound on a computer, allowing musicians to create music without physical instruments. They can recreate the sound and characteristics of real instruments or produce digitally synthesized sound. Virtual instruments come in two main types: sampling and synthesis. Sampling uses pre-recorded samples of instruments to create sound, while synthesis uses algorithms and mathematical formulas to generate sound from code. Virtual instruments can be used as plugins inside a Digital Audio Workstation (DAW) or as standalone instruments.

Virtual instruments have revolutionized the music industry since their introduction in the 2000s. They have become essential tools for both independent artists composing at home and high-profile music producers working in professional studios. With virtual instruments, musicians can access a vast array of sounds and instruments without the need for physical space or expensive equipment.

A virtual instrument is a software program that generates sound on a computer, allowing musicians to create music without physical instruments. These programs utilize a computer’s CPU, RAM, and disk space to produce sound. Virtual instruments can either recreate the sound and characteristics of real instruments or produce digitally synthesized sound.

The Structure of a Virtual Instrument

Virtual instruments consist of two main components: the sound engine and the user interface. The sound engine is responsible for generating the sound, while the user interface allows musicians to interact with the virtual instrument and control various parameters.

The sound engine utilizes complex algorithms and mathematical formulas to create sound. It can either use pre-recorded samples of real instruments (sampling) or generate sound from code (synthesis). The user interface provides musicians with controls and settings to shape the sound, such as adjusting the attack, decay, sustain, and release of a note.

Sampling: Recreating Real Instruments

Sampling is a technique used by virtual instruments to recreate the sound of real instruments. It involves recording multiple samples of each note played on an instrument, capturing different articulations, dynamics, and tonal variations. These samples are then mapped to the corresponding keys on a MIDI controller, allowing musicians to play the virtual instrument as if they were playing the real instrument.

Virtual instruments that use sampling require a significant amount of RAM and hard drive space to store the samples. Depending on the complexity of the instrument, a single virtual instrument can occupy several gigabytes of disk space. However, the advantage of sampling is that it can accurately reproduce the nuances and characteristics of real instruments, providing a realistic and authentic sound.

Synthesis: Creating Sounds from Scratch

Synthesis is another technique used by virtual instruments to generate sound. Unlike sampling, which relies on pre-recorded samples, synthesis creates sound from scratch using algorithms and mathematical formulas. These algorithms manipulate various parameters, such as oscillators, filters, and envelopes, to generate different waveforms and timbres.

Software synthesizers, also known as soft synths, are popular virtual instruments that utilize synthesis. They offer a wide range of sound design possibilities, allowing musicians to create unique and experimental sounds. Synthesis requires more processing power from a computer’s CPU compared to sampling, as it involves real-time calculations to generate sound.

Building a Sample-Based Virtual Instrument

Creating a sample-based virtual instrument involves recording musicians playing real instruments and capturing multiple samples per note. These samples are often recorded with different microphone positions and varying tones to provide a wide range of sonic possibilities. Additionally, different articulations and dynamics are recorded to give the virtual instrument natural expression.

Building a sample-based virtual instrument requires careful attention to detail. Musicians must consider microphone positions, adjust input levels for different tones, and ensure consistent playing techniques across all samples. The goal is to create a virtual instrument that accurately represents the characteristics and nuances of the real instrument.

Choosing the Right Virtual Instrument

When choosing a virtual instrument, several factors should be considered:

  1. User Interface: A user-friendly interface can greatly enhance the workflow and ease of use. Look for virtual instruments with intuitive controls and clear visual feedback.

  2. Sound Quality: The sound quality of a virtual instrument is crucial. Listen to demos and reviews to ensure that the instrument produces the desired sound and meets your expectations.

  3. System Requirements: Virtual instruments can be resource-intensive, requiring a powerful computer to run smoothly. Check the system requirements to ensure compatibility with your computer.

  4. MIDI Controller Compatibility: If you plan to play the virtual instrument using a MIDI controller, make sure it is compatible with your controller. Some virtual instruments offer advanced features specifically designed for MIDI control.

Using Virtual Instruments Live

Virtual instruments are not limited to the studio; they can also be used in live performances. To use virtual instruments live, you’ll need a dedicated laptop or computer, a DAW, an audio interface, and a MIDI controller. The laptop or computer should meet the system requirements of the virtual instrument to ensure smooth performance.

Connect the audio interface to the computer and route the audio output from the virtual instrument to the audio interface. Connect the MIDI controller to the computer and configure it to control the virtual instrument. With the right setup, you can perform live using virtual instruments, taking advantage of their versatility and wide range of sounds.
