Does Arturia make audio interfaces as well as software synths?

If you’re shopping for studio hardware, the Arturia Audiofuse 16 Rig is the audio interface in this pair. An interface handles audio going into and out of your computer; it isn’t a substitute for a software instrument.

Arturia Modular V3 sits on the sound-making side: it’s a software synth rather than an audio interface. Choose according to the gap in your setup — audio connections or another source of synth sounds — rather than treating these as competing purchases.
