10 Best Analog Synthesizers 2025 in the United States

The MOOG Subharmonicon Semi-Modular Analog Polyrhythmic Synthesizer is a robust choice for musicians seeking intricate and unique soundscapes. One of its standout features is the six tonal sources, which include 2 voltage-controlled oscillators and 4 subharmonic generators, providing a rich and complex harmonic range. This could be particularly appealing for those who enjoy creating dense, textured sound layers. The four rhythm generators add another layer of depth, allowing for complex polyrhythms by driving either or both sequencers, making it ideal for experimental music and live performances.

The two sequencers, each controlling its associated VCO and subharmonic generators, can significantly expand your creative possibilities. Another strength is its expandability and compatibility with other Eurorack modules such as Labyrinth, Spectravox, Mother-32, or DFAM, offering even more versatility and customization options. The Synthesizer's design allows for it to be used as a tabletop unit or installed in a Eurorack system, making it flexible for different setups. Connectivity-wise, it includes MIDI and a patch bay, ensuring it can integrate with various other equipment.

However, one drawback is that, being semi-modular, it might have a steeper learning curve for beginners who are not yet familiar with patching and modular synthesis. Additionally, it lacks built-in effects, meaning users will need external gear or software to add reverb, delay, etc. Those looking for polyphony might also find it limited, as it is more oriented towards monophonic and polyrhythmic capabilities. In terms of user interface, while it is designed to be intuitive for experienced users, beginners might find it somewhat overwhelming initially. Despite these potential challenges, the MOOG Subharmonicon offers a wealth of creative tools for seasoned synthesists and experimental musicians.

The Korg volca beats Analog Rhythm Machine is a compact and versatile device that caters to both beginners and experienced enthusiasts of analog synthesizers. One of its standout features is the Electribe-style 16-step sequencer with eight memory patches, which allows users to create complex rhythm patterns effortlessly. The inclusion of 10 drum parts offers a good range of sounds for various music styles. The built-in stutter effect adds a creative edge, enabling glitch or delay-like effects that can enhance your music production.

Connectivity options like MIDI In and Sync I/O ensure seamless integration with other instruments and DAWs, making it a versatile choice for studio setups. Furthermore, the device's portability is a major plus, with a built-in speaker and the option to run on battery power, allowing you to play and create music anywhere.

However, there are some areas where the Korg volca beats might fall short for certain users. The polyphony is limited, which means you can't play multiple notes simultaneously. This could be a drawback for those looking to create richer, more complex soundscapes. Additionally, while the interface is user-friendly, it may require some learning for complete beginners to get the most out of its features. The small dimensions of the device, while great for portability, might make it less comfortable for extensive use, particularly for users with larger hands. The build material is carbon fiber, which is durable but might not feel as premium as some higher-end models.

In summary, the Korg volca beats Analog Rhythm Machine is a solid choice for those seeking a portable, feature-rich analog rhythm machine, particularly if you value its compact size and versatile connectivity.

The MOOG Subsequent 25 is a paraphonic analog synthesizer and MIDI keyboard that strikes a balance between classic analog sound and modern convenience. It features 25 semi-weighted keys that are velocity-sensitive, making it responsive and expressive for live performances or studio sessions. Two oscillators and dedicated envelopes allow for rich and diverse sound creation, particularly excelling in producing powerful bass patches. The synthesizer also includes useful modes like Unison and Duo for added sonic flexibility.

The LFOs and filters work well to shape and modify the sound further, providing a robust toolkit for sound designers and musicians alike. In terms of polyphony, the 2-note paraphonic capability might be limiting for some users who need more layers in their compositions, though it's sufficient for bass and lead sounds. Connectivity is comprehensive, with MIDI In/Out/USB, audio inputs and outputs, and various CV/GATE connections, making it versatile for various setups.

Additionally, the included Editor/Librarian software simplifies preset management and integrates smoothly with DAWs. However, the compact 25-key layout could be restrictive for those accustomed to larger keyboards, and its professional-grade features might be overwhelming for beginners. This synthesizer is particularly well-suited for gigging musicians who need a portable and reliable instrument with high-quality analog sound and modern connectivity options.
