What are Modular Synths?
Modular synths take away the bulk of the pre-determined signal chain that you get with desktop synths. Imagine taking a synthesizer apart into its individual components, then being able to freely rearrange them. It’s a similar concept to a guitarists’ pedalboard; you get to choose your individual components, and place them in an order that works for you. The order is determined by patch cables that can be freely plugged and unplugged in every direction, allowing you to reroute your signal in real-time. In a nutshell:
- Total control over your signal chain
- Customise your sound by adding as many modules as you like
- Modules can take many forms; oscillators, filters, mixers, effects units – endless!
- Designed to be totally cross-compatible with most hardware
- Often designed with universal connections and form factors
- Most are analog, but some digital options available (effects etc.)
The Pros of Modular Synths
As mentioned above, having total end-to-end control over your setup has proved to be an irresistible concept from day one. With modular and Eurorack setups, you can literally choose which component affects which, unlocking a near-limitless palette of sound and creativity. You can use oscillators to affect volume, envelopes to affect filters, voltages to control tempo – the works. You literally have the ability to find a sound that no one has ever found before. There’s also the unparalleled sense of satisfaction at carving out a killer sound all by yourself, from scratch. This writer can’t help but think of it as being similar to the pride of a parent with a new-born child…
…back to reality. Where desktop synths can sometimes be expanded, modular synths are designed to be – that’s the whole point. Easily add another modular to your chain at any chosen slot. You could synchronise your setup with other hardware, connect it up to your DAW to incorporate in-depth sequencing. You can choose any input source you like; MIDI controllers, analog sequencers – even sampled audio or a guitar!
Modular setups, much like a guitar pedalboard, can be tweaked with practicality in mind. Shrink it down and it’ll easily fit into a carry case or slot into an overhead luggage compartment. As mentioned earlier, many Eurorack-style cases are built to be portable and practical. Handles, padding, rugged reinforcement. This makes it super easy to take your modular setup wherever you want to go – boundless creativity is always within reach.
Finally, and once again comparable to a pedalboard, there’s the collectible aspect. Your collection of modules arranged neatly (or messily!) bleeping and blooping in spectacular sci-fi fashion can be an immense source of pride and joy. It’s this collectible aspect of modular setups that lures in so many unsuspecting gear enthusiasts. Once you’re bitten by the bug, you’ve got it for good.
The Cons of Modular Synths
When it comes to cons of the modular approach, you can essentially turn the best bits of desktop synths on their head.
Modular synths can be fiddly and difficult to get used to – remember, you’re starting from scratch. No prefab signal chain hand-holding – you’re on your own now. It can be a steep learning curve whichever way you approach it. There are countless resources, both print and digital, to help you along the way, but there’s a lot of info to take on board. Or if you’re more of an immersive learner, prepare yourself for a real slow-burning process. The reward is arguably worth the wait – but bear this all in mind!
Again, further to the points we made earlier, modular can end up being pricey. When you compare a multi-FX with a proportionate number of single guitar pedals, it starts to make sense. Having total control of your sound and setup is wonderful – but the price of individual components, combined with their addictive collectible nature, can very quickly become costly! If you decide to take the modular path, be wary of spiralling costs and budget sensibly. Or just follow your dreams and go all-in…
