The Novation Summit is a robust synthesizer that stands out in the polyphonic synthesizer category, designed for musicians and producers looking for a versatile instrument. With its two-part multitimbral capability and 16-voice polyphony, it allows for complex sounds and layers, making it suitable for live performances and studio recordings alike. The three new Oxford Oscillators per voice provide various synthesis options, including subtractive, wavetable, and FM synthesis, offering a wide sound palette to explore. The analogue multimode filter adds depth to the sound, allowing you to shape tones effectively.

One of the Summit's highlights is the five-octave semi-weighted keybed, which is responsive thanks to its velocity sensitivity and aftertouch. This feature enhances playability and expression, crucial for live musicians and those who enjoy dynamic performance. Additionally, the inclusion of onboard effects like distortion, chorus, delay, and reverb enriches the sound without needing external gear.

Connectivity is another strong point, with stereo audio-in that can be routed to the onboard effects, making it easy to integrate other instruments or sources into your setup. USB connectivity adds to its versatility, allowing for seamless integration with computers and other devices.

Roland JUNO-D8 Synthesizer | 88-Note Weighted Keyboard with Hammer Action | ZEN-Core Engine with Over 3800 Onboard Sounds | Intuitive Creative Tools | USB-C Audio/MIDI Interface for Mobile & Computers

The Roland JUNO-D8 Synthesizer stands out for its blend of professional sounds and user-friendly features. It has an 88-note weighted keyboard with hammer action, making it feel like a traditional piano, which is great for both seasoned players and beginners. The ZEN-Core engine provides access to over 3800 onboard sounds, ensuring a wide variety of tones and textures for different musical styles. You can further expand your sound library with Sound Packs and Wave Expansions through Roland Cloud, adding flexibility and creativity to your music production.

The sample import function allows you to play and edit your own WAV files, giving you even more customization options. The USB-C audio/MIDI interface makes it easy to connect to mobile devices and computers, ideal for modern, on-the-go musicians. On the downside, at 32 pounds, it's relatively heavy, which might not be convenient for frequent gigging musicians. Its price point could also be a consideration, given the advanced features and professional quality it offers.

For those looking for a robust and versatile synthesizer that can handle a variety of musical tasks, the JUNO-D8 is an excellent choice. The instrument's intuitive workflow ensures that users can easily navigate and make the most of its capabilities, enhancing the playing and creative experience.

Buying Guide for the Best Synthesizers

Choosing the right synthesizer can be a thrilling yet daunting task, especially with the wide variety of options available. Synthesizers are electronic instruments that generate audio signals which can be transformed into sound. They are used in various music genres and can produce a vast array of sounds, from traditional instruments to unique, otherworldly tones. To find the best synthesizer for you, it's important to understand the key specifications and how they align with your musical needs and preferences.
Type of SynthesisThe type of synthesis refers to the method a synthesizer uses to generate sound. Common types include subtractive, FM (frequency modulation), wavetable, and granular synthesis. Subtractive synthesis is great for classic analog sounds, FM synthesis is known for its complex and metallic tones, wavetable synthesis offers a wide range of evolving sounds, and granular synthesis is perfect for experimental textures. Your choice should depend on the kind of music you want to create. If you're into classic rock or pop, subtractive might be your go-to. For more modern or experimental music, FM or wavetable could be more suitable.
PolyphonyPolyphony refers to the number of notes a synthesizer can play simultaneously. Monophonic synthesizers can play only one note at a time, which is ideal for bass lines and lead melodies. Polyphonic synthesizers can play multiple notes at once, making them suitable for chords and more complex arrangements. If you plan to play intricate pieces or need to layer sounds, a polyphonic synthesizer with higher polyphony (e.g., 8, 16, or more voices) would be beneficial. For simpler, single-note lines, a monophonic synthesizer might suffice.
OscillatorsOscillators are the primary sound generators in a synthesizer. They produce waveforms that form the basis of the sound. The number and type of oscillators can greatly affect the sound's richness and complexity. More oscillators allow for thicker, more complex sounds. Common waveforms include sine, square, sawtooth, and triangle, each offering a different tonal quality. If you want rich, layered sounds, look for synthesizers with multiple oscillators. For simpler, more straightforward sounds, fewer oscillators might be enough.
FiltersFilters shape the sound by removing certain frequencies. The most common types are low-pass, high-pass, band-pass, and notch filters. Low-pass filters remove high frequencies, making the sound warmer, while high-pass filters remove low frequencies, making the sound brighter. Band-pass filters allow a specific range of frequencies to pass through, and notch filters remove a specific range. Filters are crucial for sound design, allowing you to sculpt the tone to your liking. Depending on your music style, you might prefer a synthesizer with versatile filter options.
ModulationModulation refers to the ability to change a sound parameter over time, adding movement and complexity to the sound. Common modulation sources include LFOs (low-frequency oscillators) and envelopes. LFOs can modulate parameters like pitch, filter cutoff, and amplitude, creating effects like vibrato and tremolo. Envelopes shape the sound's attack, decay, sustain, and release (ADSR). If you want dynamic, evolving sounds, look for synthesizers with extensive modulation options. For more static sounds, basic modulation capabilities might be sufficient.
ConnectivityConnectivity options determine how you can integrate the synthesizer with other equipment. Common connections include MIDI, USB, CV/Gate, and audio outputs. MIDI and USB allow you to connect the synthesizer to computers and other MIDI-compatible devices, essential for studio setups. CV/Gate is used for connecting to modular synthesizers and other analog gear. Audio outputs are necessary for connecting to speakers, mixers, or recording devices. Consider your existing setup and how you plan to use the synthesizer to determine the necessary connectivity options.
User InterfaceThe user interface affects how easily you can navigate and control the synthesizer. Some synthesizers have a lot of knobs, sliders, and buttons, providing hands-on control, while others rely more on menus and screens. A more tactile interface can be more intuitive and faster for live performance, while a menu-driven interface might offer deeper editing capabilities. Think about how you prefer to interact with your instrument and whether you need quick access to parameters or are comfortable diving into menus for detailed sound design.
