Audiothingies is the brand name of MCDA, a small French company based in Dijon and founded in 2014 by Samuel Montassier. The operation is boutique in scale, focused on designing and manufacturing compact, affordable electronic instruments — with a tagline the company sums up as "things that can make sounds."

The brand is best known for the MicroMonsta line of desktop polysynths. The original MicroMonsta was a small 8-voice virtual-analog synth with wavetable support, discontinued after key components became unavailable and succeeded by the MicroMonsta 2, a bi-timbral polysynth with three oscillators per voice, filter FM, and onboard reverb. Earlier products include the P6, a DIY polysynth kit that predated the MicroMonsta, and the DoubleDrummer, a compact drum synthesizer. Other past releases include the Doctor A, Midibro, and CED.

Audiothingies occupies a niche favored by home-studio and electronic producers looking for full-featured polyphony in a small, keyboardless desktop form factor at a lower price point than mainstream hardware synths, and the MicroMonsta series in particular has developed a following on synth-focused forums and YouTube channels.

Audiothingies has 5 products cataloged on Equipboard, including Synthesizers, Drum Machines, and Effects Processors. Their gear is featured by 3 artists, with the strongest followings in Electronic. Notable users include Chet Faker, Vitalic, and Ricky Tinez.
