The blend of rhythms produced when musical synthesis plays brings a relieving or entertaining illusion that one’s mind yearns. Consider the musical fusion from analog or digital synth, and the differences are outstanding. Generally, the digital synth is upgrading from the analog synth in various ways that you will discover as you proceed reading through. But they come with different features and functions. Let’s see the analog vs digital synth comparison.
What is Analog Synth?
A synthesizer is an electronic musical instrument that produces vocal audio signals.
An Analog synthesizer uses analog signals to generate sound electronically. It uses a voltage-controlled oscillator through subtractive synthesis, additive synthesis, and frequency modulation synthesis.
The earliest analog synths such as Trautonium were produced between 1920 and 1930 and came with some distinct features:
- Thermionic valve and electro. Mechanical technologies which synthesize bass sound. To date, it is still sought after to simulate the same effects.
- Sound mixers. The synthesizers had effect devices, including reverb units such as sequencers, to mix sounds and bring on the intended blend.
- Monophonic. With this feature in the analog synth, only one note could be playing at a time, thus the name mono for one.
- Vocoders: These had specialized features that were based on equipment based on speech synthesis. They made a sound similar to that of the singing of talking musical instruments.
Advantages of Analog Synth
- A hand-on experience – The most obvious advantage of the synth is that it has a solid piece of hardware that allows a more hands-on experience to the user.
- Time dedication – With Analogue Hardware synth, the user can dedicate more time to master it, depending on personal experience. Here then, calls for undivided attention by the user master it thoroughly. For a beginner, more time will be needed to master the instrument to understand it well.
- Low costs – Since these are traditional synths that are not so advanced and since they are no longer popular, there are low entry costs, especially when buying them and maintenance costs.
- Holds its value more than a software synth – In the long term, this system will last longer and hold more value, especially if you buy the older analog hardware synth. Its production emphasized more on quality than on quantity and as such price was carefully considered.
Notable to these analog synths is that after 1960 they were improved to use operational amplifier integrated circuits and potentiometers for sound adjustment. They could now change its sound using low-pass as well as high pass filters.
Later on, the synths would be upgraded into single units to eliminate patch cords and integrated signal routing systems and stopped using the patch cables to connect the modules. Top in the list of the best analog synthesizers used by musicians then was Korg Minilogue 4-Voice Polyphonic Analog Synth, Moog Grandmother Analogue Synthesizer, among many others.

What is Digital Synth?
The synth uses modern signal processing techniques to produce sounds of the music. The introduction of computers back in the 70’s enhanced the practicability of production of sound synthesis.
With its system, it creates a line of numbers that produces sounds from speakers. At Stanford University, John Chowning experimented with the frequency modulation synthesis in 1971, and soon after, Yamaha’s engineers adapted his ideas to produce digital synthesizers.
However, they improved on ‘key scaling’ to eliminate the diversion of sounds that were realized during frequency modulations under analog systems.
The very first commercial digital synth was launched in 1979, namely the Casio VL-1, and sold high.
Yamaha followed in the line of industrial production and released its first synthesizer in 1980, namely, GS-1. These digital synths came with distinct features that gave them an added advantage to the analog synths. The features included:
- Hardware features consist of Direct Digital Synthesis (DDS) that produces the squeak excitation. By nature, the waveforms are a different shape and sound better. Many people prefer hardware synth features and enjoy better music composed.
- Workstation synthesizer is an in-built feature that hosts many tracks sequencers. It can record, playback many vocal samples, and record an entire song in the long run.
Advantages of Digital Synth
- Software versions – There are now many software versions of many vintage synths created as digital virtual software instruments. With technological advancement, you can certainly be sure that more improvements in software versions will always come up.
- Cost – Due to the high number of software available and many users, the digital software synth is much lower for a buyer. Once the first piece of software has been produced, it can be widely distributed to reach many users with no other costs.
- Workflow and space, and don’t break easily – It becomes easier to load up a digital software synth than find the right hardware synth, turn it and start recording in your DAW. If the analog synth breaks, you can easily get the parts of someone who knows how to repair it.
The digital synth, advanced with modern technological advanced control systems, enhances its performance with user-friendly physical controls like buttons for selecting features and knobs for setting relevant parameters.

Analog Vs. Digital Synth
You often ask yourself which synth to use; analog vs. digital. With the reproduction of hardware synths and the electronic nature of the same, many people are increasingly turning from analog hardware equivalents to software solutions.
Most users in the current generation prefer to go for easy-to-do tasks with quick-to-get-results. They do not want to associate with hard tasks that may not yield results faster.
Analog vs. Digital Synth Similarities
Both Analog and Digital Synth share some similarities right from their structure to their functionality:
- Sound quality – Analog synth creates sound by circuits and modulators, while digital synth has a piano keyboard and an LCD as an interface to produce sound. When it comes to quality, both produce high-quality sounds.
- Oscillators to convert power supply – Digital synth uses numerically controlled oscillators, and analog uses a voltage controlled oscillator.
- Still in use, even to date – The analog synth is mostly preferred by the older generation, whereas the current generation prefers to use a digital synth. The analog synth has not been declared obsolete as yet since the digital one came into existence. The user determines which synth to go for, and availability is assured.
- A long history of upgrading to better quality – Analog synthesizers such as Moog had to be integrated into single units to eliminate patch cords for better performance. Similarly, the digital synth has included sampling capability and digital signaling processing features for improved performance.
- Sound production uses analog features in both synths – In the digital synth, the sound from speakers is usually created by an adaptation to analog form. With technological development, the analog synth is upgraded to incorporate production software, and the market of suppliers will be lost for a choice between the two synths.
Analog Vs. Digital Synth Differences
These two systems, in as much as they perform similar tasks differ in various ways as is tabulated below:
| Parameter | Analog | Digital |
| Processor | Analog synth uses analog circuitry and a phase-locked loop. | Uses digital processors and also direct digital synthesis |
| Oscillator | Uses a voltage-controlled oscillator | Uses a numerically-controlled oscillator |
| Sound production | Produces sound through sound-generating circuitry and modulators | It uses a computer that has an LCD as an interface on as well as a piano-keyboard. |
| Features | Contains fewer features due to its physical composition | Offers more features with the help of computer technology advancement |
| Synthesis | Does not have some form of integrations like sampling and additive synthesis | Has many combinations, including sampling and additive synthesis |
| Preference | Many known musicians prefer the character of analog synthesizers | Not many known musicians prefer digital synthesizers, especially those that are technologically not upgraded. |
| Founder | The origin can be traced back to as far as 1876 by Elisha Gray | It is believed that pioneers such as Robert Moog brought their synth into the mainstream back in the 1960s. |
Is there still any value of purchasing a hardware analog synth in this digital era?
With the development of technology, not many users will want to go back to the history of doing things manually. Besides the availability of software solutions over the traditional analog hardware equivalents, the transition has given a niche to each of these two synths.
Still, it is left at the discretion of the user to determine which way to go. The current generation considers the availability of software to fasten the production of lots of music without requiring hardware anymore. There is also a variety of software solutions to choose from, and prefer not to buy hardware analog synth anymore.
Conclusion
We all know that music is a vital factor in our lives. It is always good to relax your mind with some soothing music after or during your daily activities. However, music can only be exciting with the right instrumentals in place.
The analog and digital synths offer such a great and remarkable musical feeling. Both the analog and digital synths serve the same purpose. However, the type of sound you’ll need from the synth mentioned in the above features will help you decide on the type of synth to choose as per your preference.
