ADDAC develops instruments for sonic expression.

We started with an ambition to explore the potential crossover between analog synthesizers and computers. Because our first creations sparked a lot of attention, we decided to work hard and put them in your hands.

Our product line is focused on a new breed of hybrid synths, that combine the best of both the digital and analog worlds. We've grown to be able to reach thousands of enthusiastic clients, friends and collaborators. Always looking into conceptualizing and developing the most exquisite instruments, we hope you're able to join and share this passion with us.

ADDAC207, ADDAC802 Quintet Mixing Console, ADDAC601 VC Fixed Filterbank, ADDAC200B 2HP Buffered Multiples and ADDAC703 Discrete Mixer are among ADDAC Systems most popular products.
