Tomas Nordelius is an engineer at Clavia/Nord and a key contributor to the company's synthesizer architectures, likely related to founder Hans Nordelius in the Swedish family business tradition.

Tomas worked on the Nord Wave, a synthesizer combining virtual analog, FM, wavetable, and sampling engines in a single performance instrument with Nord's signature hands-on control surface.

He also contributed to the Nord Modular, a software-programmable modular synthesizer system that allowed musicians to configure virtual modules on a computer and play them from a dedicated hardware interface — an ambitious project ahead of the Eurorack revival.
