Empty Room Systems is a company started by Harrie Munnik and Theo Fokkema. After working on some other projects together and both being enthusiastic about audio gear, effects, vintage sounds and computers they decided to develop a native VST plugin inspired by the first digital hardware-based reverb, the EMT 250
Their products serve quite different purposes - from document management to entertainment. However, all these products have one thing in common: They combine technological know-how with the results of research in software engineering and human-computer interaction. In other words: They are powerful and still easy to use. Products include Easy Beat.
