Company history

Expert Sleepers started making VST plug-ins in 2002, the first product being Crossfade Loop Synth (which is still available today, in a much udpated form).

We started our modular journey in 2009 with the release of Silent Way.

Our first hardware product, the ES-1, was released in 2010.

Expert Sleepers became Expert Sleepers Ltd in 2013.
