However, there may be times when you want to convert your polyphonic synthesizer into a monophonic one. Perhaps you want to achieve a specific sound or emulate the vintage analog synths of the past. Whatever your reason may be, this article will guide you through several methods to make a polyphonic synthesizer monophonic.

Understanding the Difference Between Polyphonic and Monophonic Synthesizers

Before we dive into the methods of making a polyphonic synthesizer monophonic, let’s first understand the fundamental differences between these two types of synthesizers.

A polyphonic synthesizer is capable of playing multiple notes simultaneously, allowing for the creation of chords and complex harmonies. It typically has multiple oscillators, envelopes, and filters that can be assigned to different voices or notes. This makes polyphonic synthesizers ideal for playing melodies and harmonies in a wide range of musical genres.

On the other hand, a monophonic synthesizer can only play one note at a time. It has a single oscillator, envelope, and filter, which gives it a unique and focused sound. Monophonic synthesizers are often associated with classic analog synths and are favored for their ability to create powerful lead sounds and basslines.

The decision to choose between a polyphonic or monophonic synthesizer depends on the specific needs of your music production. If you’re looking to create complex arrangements and lush soundscapes, a polyphonic synthesizer would be your go-to choice. However, if you’re aiming to create driving basslines, mesmerizing lead melodies, or vintage-inspired sounds, a monophonic synthesizer will be your best bet.

Now that we have a clear understanding of the differences between these two types of synthesizers, let’s explore the reasons why you might want to make your polyphonic synthesizer monophonic.

By focusing on a single voice, you can experiment with different modulation sources, filters, and envelopes, resulting in more adventurous and unique sound design outcomes.

Now that you’re aware of the reasons for making a polyphonic synthesizer monophonic, let’s explore the various methods you can use to achieve this transformation.

Method 1: Disabling the Oscillators

If you want to convert your polyphonic synthesizer into a monophonic one, one method is to disable the oscillators. The oscillators are responsible for generating the sounds in a synthesizer, and by disabling them, you can limit the synthesizer to playing only one note at a time.

Here are the steps to follow:

1. Locate the oscillator section of your synthesizer. This can typically be found in the sound generation or voice section of the synthesizer’s control panel.
2. Identify the controls or settings that allow you to turn off or mute the oscillators individually or collectively.
3. Disable all but one oscillator. This will ensure that only one note can be played at a time.
4. Adjust the settings of the remaining oscillator to achieve the desired sound. Experiment with different waveforms, tuning, and modulation options to create a captivating monophonic sound.

This method works well for synthesizers that have individual control over each oscillator. However, some synthesizers may not have the option to disable individual oscillators, especially if they are designed primarily for polyphonic playability. In such cases, you may need to explore other methods to make your synthesizer monophonic.

Remember to consult your synthesizer’s manual or documentation for specific instructions on how to disable the oscillators, as the process may vary depending on the make and model of your synthesizer.

Now that you know how to disable the oscillators, let’s explore another method to make your polyphonic synthesizer monophonic.

Method 2: Restricting the Voices

Another method to convert a polyphonic synthesizer into a monophonic one is by restricting the voices. Voices refer to the number of simultaneous notes that can be played on a synthesizer. By limiting the number of voices to one, you essentially create a monophonic playing capability.

Here’s how you can restrict the voices on your synthesizer:

1. Access the voice settings or polyphony parameters on your synthesizer. These settings determine how many voices can be played simultaneously.
2. Set the maximum number of voices to one. This will ensure that only one note can be played at a time.
3. Adjust any other voice-related settings such as voice stealing algorithms or voice priority to suit your preferences.
4. Experiment with the envelope, filter, and modulation settings to shape the character and behavior of the monophonic sound.

Restricting the voices is a common method used by synthesizer enthusiasts and performers who want to transform their polyphonic synthesizers into monophonic instruments. By limiting the number of voices, you can achieve tighter control over the sound and focus on creating expressive lead melodies and basslines.

Keep in mind that some synthesizers may have a fixed number of voices, and may not offer the option to restrict or adjust the polyphony. In such cases, you can explore other methods to achieve a monophonic result.

Now that you’re familiar with the second method, let’s move on to explore another technique to make a polyphonic synthesizer monophonic.

Method 3: Modifying the Circuitry

If you’re comfortable with electronics and have a good understanding of synthesizer circuitry, modifying the circuitry of your polyphonic synthesizer can be an effective method to make it monophonic. This method requires technical knowledge and skill, so proceed with caution and at your own risk.
