If you play string instruments, you know how annoying an out-of-tune instrument can be. It’s a real headache. Pianos are string instruments, so they can also go out of tune. But if you’re a keyboard player, specifically a synth player, you might wonder if your synthesizer can also go out of tune. Let’s explore synthesizers, whether they can go out of tune, and how to prevent them so you can keep making beautiful music.
Can a synthesizer go out of tune? Digital, virtual analog, and wavetable synthesizers produce notes digitally, which means they don’t go out of tune. On the other hand, analog synthesizers can experience tuning issues.
What is a synthesizer?
A synthesizer is an electronic instrument that can make sound using digital or analog signal processing. Most synthesizers try to mimic (or “synthesize“) the sounds of acoustic instruments. But synthesizers that try to sound like acoustic instruments make sounds different from the real ones.
For example, the “piano” preset on many electronic synthesizers makes the instrument sound like an 88-key classical piano, even though it is made by a collection of electronic tone generators. A piano’s sound is created by a felt hammer hitting tuned strings, which doesn’t happen with a synthesizer.

What does being out of tune mean?
The key signature of a song indicates which scale notes go well with it. So, to be “out of tune” is to play in a key or scale other than the one intended. So when a singer or musician is “out of tune,” some of their notes are off-pitch and don’t work well within the key signature of the song they’re performing.
How can a synth go out of tune?
Analog synthesizers can go out of tune due to a tiny “drift” in tuning. This is why many people continue to pay exorbitant prices for the “classic” synthesizer sound. The “drift” is caused by several elements inherent to the synthesizer’s circuitry. The following are examples:
- Temperature changes in analog circuits cause tuning drift.
- Changes in electromagnetic interference cause tuning instability.
- Aging circuit components cause a change in tune.
That is to say, the environment, electrical interferences inside the circuitry, or the fact that the synth is getting on in years.
How do you know if your synth is out of tune?
There are several ways to check if a synth is tuned correctly. You would use it the same way as any other musical instrument—by using a tuning fork and listening to the precision of the note. You can tell if your synth is out of tune, if the notes sound dissonant when playing chords or intervals if certain notes consistently sound off-pitch, or if the pitch fluctuates or wavers unexpectedly.
How to tune a synthesizer?
How do you prevent your synthesizer from going out of tune?
You can only do a little to prevent your synth from being out of tune. Getting the most out of a vintage analog synthesizer requires letting it warm up first. Some synthesizers need up to 30 minutes to calm down and be roughly in tune after doing this. Generally, older synths will take longer to warm up.
The synthesizer should be kept in a clean space when not in use. And if you have no other option, let it warm to room temperature again before turning it on. Other than this, there isn’t much you can do to stop it. It’s a big part of what makes so many synthesizers unique and special. And, honestly, you won’t mind the tuning frequency if you play another instrument, like a guitar.

Frequently asked questions (FAQ)
Do you still have questions? Below are some of the most commonly asked questions about synthesizer tuning.
Can I tune my synthesizer to different scales or alternate tunings?
Yes, many synthesizers offer the flexibility to adjust the tuning to different scales or even create custom tunings. This feature is common in digital and software synthesizers. You can explore various temperaments, microtonal scales, or alternative tuning systems to experiment with unique musical expressions and genres.
Why do analog synths go out of tune?
Analog synths go out of tune due to something called “drift.” A drift is caused by several elements inherent to the synthesizer’s circuitry. For example, when the environment’s temperature changes, electromagnetic interference can cause the tuning of analog circuits to drift.
What is the difference between tuning a monophonic and polyphonic synthesizer?
When tuning a monophonic synthesizer, you typically focus on calibrating a single oscillator to ensure accurate pitch. In contrast, polyphonic synthesizers feature multiple oscillators, often one for each voice.
While analog synths are prone to going out of tune, digital synths are rarely out of tune. However, this doesn’t mean you can’t tweak your settings now and then. If it happens a lot, check the tuning software or turn up the volume halfway. It’s also a good idea not to practice with headphones on to avoid being distracted by outside noise.

This article covered what a synthesizer is, what “out of tune” means, and how a synth can go out of tune. Here are some key takeaways:
- A synthesizer is an electronic instrument that can make sound using digital or analog signal processing.
- Musically, to be “out of tune” is to play in a key or scale other than the one intended.
- Compared to digital synthesizers, analog ones have more personality due to a tiny “drift” in tuning that can’t be replicated.
- Synths are grouped into two broad groups regarding tuning, and the first group is a synthesizer with no pitch knob.
