Early Samplicity

Samplicity was started in 2005 as a hobby project by Peter Roos, with the creation of highly acclaimed impulse responses from professional reverb devices like the TCE System 6000 and the Lexicon 960L. After a few years, a new IR collection was made with the new and impressive Bricasti M7 reverb unit. Being a free IR library – explicitly allowed by Casey Dowdell from Bricasti Ltd. as stated in online discussions – this library became very popular and has been downloaded more than 100,000 times from the Samplicity website. Another reason for the success of this library is the very accurate and pristine capture of the M7’s reverb presets, thanks to Samplicity’s special recording and post-processing methods.


Peter holds a master’s degree in psychology (perception research) and a master’s degree in data-analysis and statistics. Peter has been an independent IT professional since 1997, mainly as UX/UI designer and front-end developer. Earlier Peter was a full-stack software engineer, working on portable PC and Apple software for laboratories in the food industry and academic research centers.

Fast forward

Since early 2021 Peter is working full-time for Samplicity. He first created a very efficient, proprietary convolution engine as the core for Samplicity reverb plugins and future immersive 3D sound applications. This technology features multi-channel and multi-threaded processing, smooth realtime filter updating, separate treatment of early reflections, last reflections and reverb tail components, and perception-based optimizations.

Some uses of Samplicity’s impulse responses

Samplicity impulse responses have been used in many music productions – even in the live music mixes of the Olympic Winter Games Ceremonies in Sochi (2014), heard by hundreds of million people.

A number of custom Samplicity IRs are embedded in products by Heavyocity, Scarbee and Orchestral Tools.

Guys, I strongly recommend you get this one. It’s a fantastic set of reverb impulses and super cheap for what you get, considering that the real hardware is 11 grand! A no-brainer for anyone doing orchestral music, in my opinion
