Modularity is all over the place. It is at the forefront of synthesis technology while yet being the oldest. It’s a new-old, future-retro, historical, and forward-thinking approach to music-making that takes advantage of our rediscovered love of tactile engagement. While the beautiful flashing lights and swaths of cables are enticing, they may also be rather complicated. Nowhere is this more true than when you’re trying to get started in modular. As you add more modules and discover new ways to make music, modular synthesis has the ability to grow, expand, and change. As a result, I’ve had to take some liberties in compiling a list of the best modular synthesizers.
What we’re looking at is a self-contained device or set of modules that can be used independently. In most cases, this means a “Semi-Modular” synthesizer, in which the modules are linked up internally to ensure that the synthesizer always works. In other circumstances, it’s a collection of discrete modules presented as a comprehensive solution by a manufacturer. The most important feature is that they can all be patched into a larger modular system.

- Switchable harmonically rich sine wave.
- External preamp with independent 30x gain and output level controls.
The Pittsburg 3900 is a contemporary semi-modular with a slew of innovative features. The instrument’s audio engine can feed a collection of waveshapers from harmonic shaping thanks to its regulated temperature and dual VCA oscillator core. Sonically, this generates a flowing filter that gives the oscillator more vitality and depth. As a result, you may make the synth scream as loud as you want.
Pittsburg 3900’s sound is powered by innovative dynamic VCA technology. A typical VCA has two aspects of operation. Pittsburg 3900’s dynamic VCA technology, on the other hand, has a third dimension. Harmonics are removed when VCA technology closes and restored when it opens. It’s also designed to allow the synth to be plucked, which opens up a whole new world of musical possibilities. The instrument is patched internally, so no patch cords are required to dial in a variety of tones. For total signal routing control, it has a 39-point Eurorack.
Creating dynamic sounds is aided by a four-stage envelope generator, broad LFO, multi-tasking function generator, and sequencer. The innovative binary filters etched around the filter circuit use a smooth 2 pole to provide a smooth frequency. The sound is sculpted by a 30x symmetrical overdrive circuit in the output portion. It produces high-quality, harmonious happiness as a result. The periodic control voltage generator can be used as a voltage-controlled oscillator or a decay-attack envelope generator, among other things.

Inverted and positive outputs, end trigger outputs and gate inputs, as well as modulation inputs for control, are all present in both functions. Volca Modular has patchable outputs from a separate CV input, as well as the sequence, for control. The input port is a stereo 3.5mm jack connector, which allows for signal separation.
Frequently Asked Questions
What is a modular synth?
The modular synth, invented in the 1950s, is that jumble of cords and flashing lights you’ve seen in a studio or on a friend’s desk and wondered how it could ever qualify as a musical instrument. A modular synthesizer is a music or sound-design instrument made up of many modules. The voltage control amplifier (VCA), voltage control filter (VCF), voltage control oscillator (VCO), envelope, effects, LFO, and utility modules are the most common types of modules. These modules might be digital or analog in nature (controlled by voltage).
Wires link the modules, with VCO -> VCF -> VCA being the conventional patching. The connecting cords are always mono and come in a variety of sizes, including huge jacks, banana plugs, and miniature plugs. A modular synth (synthesizer) provides a one-of-a-kind capacity to create customised sounds. These synths are so adaptable that you can generate sounds with the oscillator of one instrument and the filter or clone of another device — from a different manufacturer! Yes, you can use the synth without a DAW to create a whole soundtrack or album (Digital Audio Workstation).
