- The guitar synthesizer is an electronic instrument that has undergone several iterations but commonly refers to a synthesizer module that receives information from a guitar-like controller to output sound. This can be done through an onboard pickup or a dedicated guitar that sends information to a floor module.

What is a Guitar Synthesizer? MIDI control is tailor-made for keyboard instruments since switches produce non-ambiguous information. They are either on or off. Getting a conventional electric guitar or bass to control a synthesizer is different. The development of guitar synthesis has branched in many directions.
Nov 16, 2023 · With anywhere from 25 to 88 keys, keyboard synths are the obvious go-to for any live performer or producer who wants easily accessible sound at their fingertips. The downside of keyboard synthesizers is their often bulky build, which can take up precious studio space and be annoying to transport.
May 23, 2023 · Guitar synthesizers work by analyzing the input signal from a guitar’s pickups and using software algorithms to map that signal onto a digital sound wave. These algorithms can use a variety of techniques to generate a wide range of sounds, including signal processing, filtering, and modulation.

Before I go on, I do want to make one point: the type of synthesis we’re dissecting here is subtractive synthesis. Subtractive synthesis is the most commonly used category of synthesis, and it’s defined as a method of sound synthesis in which partials of an audio signal (often one rich in harmonics) are attenuated by a filter to alter the timbre of...
One other term I need to cover before I dive in is control voltage, or CV. Control voltage is, more or less, the internal language of analog synthesizers. This voltage does not represent audio but controls different elements of a synthesizer that create audio. For instance, the keys on an analog synth keyboard send different CV values to the oscill...
Oscillator
If anything is the heart of a synthesizer, then it’s the oscillator. It produces a raw, unfiltered sound wave. In a garden-variety analog synthesizer, an oscillator will generate a saw wave, square wave, sine wave, triangle wave, or noise. In digital synthesizers, the core of the oscillator can be a wavetable or even a recorded sample. The sound sample below is a saw wave — the way you would hear it if you directly tapped the audio output of an analog oscillator. Note that it just keeps going...
Amplifier
Every synthesizer has an amplifier, or, more accurately, a variety of amplifiers. Often seen abbreviated as VCA (voltage-controlled amplifier)and DCA (digitally controlled amplifier), the amplifiers are the components that determine exactly how much signal from the oscillator gets passed on to the next part of the synthesizer. The name “amplifier” is a bit misleading and confusing, though. Technically speaking, an amplifier is part of a circuit that boosts signal, but in synthesizers, the amp...
Filter
In the context of a synthesizer, a filter is a module that removes certain frequencies from the audio signal, much like an equalizer on a stereo or a recording console. The most commonly found filter types on an analog synthesizer are lowpass (LP)filters, which filter out high frequencies and let low frequencies pass (hence the name), and highpass (HP) filters, which filter out low frequencies and allow high frequencies to pass. You may also see bandpass (BP) and all-passfilters on certain sy...
These terms often throw people off. What the heck is a gate? Why do we need it? To oversimplify it a little bit, the gate signal tells the synthesizer when a note starts and when it ends. Here’s an example: a keyboard can generate a gate signal, which begins when the key is pressed and ends when the key is released. A sequencer could generate gate ...
Hopefully, you found some helpful information in this basic rundown of synthesis concepts. To the uninitiated, this may seem like a lot of information, but I promise you that there’s a whole lot more where that came from. The limitless flexibility of synthesizers is one of the things that makes them so appealing, and the huge variety of synthesizer...
A guitar synthesizer is any one of a number of musical instrument systems that allow a guitarist to access synthesizer capabilities.
Jul 17, 2018 · As you have likely noticed by now, there’s a lot to learn when it comes to synths. In this article, I merely scratched the surface by showing you key parameters, a few types of synthesis, and the basics of modulation. The best way to create great synth sounds is through experimentation.
