Jaroslav Holub is a professional producer, sound engineer, and multi-instrumentalist born on September 25, 1985. He is also the husband of the most amazing wife in the world and the father of 3 beautiful children.

In 2001 he started actively performing with local bands as a drummer. His love for drums has remained with him to this day. It is still the main instrument he is most dedicated to. This is matched by the ever-growing number of presets for Superior Drummer 3 on his production store.

As a great lover of new technologies and products in audio, he is constantly equipping his Develop Device studio with more exciting gear. Currently, he specializes mainly in guitar modelers, for which he offers many presets.

Develop Device is also the name of Jaroslav's one-person modern metal project. What makes it unique is that only VSTi instruments Jaroslav uses to write the music for the most part. Develop Device songs can be listened to here.

Over time, Jaroslav has gained the trust of many world-renowned artists with whom he has had the privilege to work. These include Jeff Loomis, Ahrue Luster, Dan Brown, Magnus Karlsson, Charlie Scene, Paul Wardingham, etc.
