If you want to start building your own modular synth, you could do worse than to pay a visit to London Modular. Located in the UK capital’s Hackney Wick, the modular experts know all there is to know about the world of Eurorack, counting Mumdance, Aphex Twin and Radiohead among their customers.

The people behind the store aren’t just salesmen though – they make music as London Modular Alliance, touring their hardwareheavy setup across Europe and beyond, releasing on labels such as ART, Hypercolour and, most recently, Dimensions Recordings.

FACT visited the store and challenged two of the trio, Phil Ventre and Gavin Pykerman, to make a track in just 10 minutes using the array of hardware available in their showroom. It’s an instore demo like you’ve never seen before.
