Around 1988 Corona acquired some more sophisticated equipment. His first professional keyboard was a synthesizer, the Kawai K1. Corona was “blown away” by the concept of designing his own sounds with oscillators and waveforms. He also began to program sounds on the Commodore 64. He started to write his own compositions influenced by techno pop (e.g. Kraftwerk), acid house and industrial. He continued in that style by forming the live act Vortex together with two of his friends. The group was active from 1988 to 1991.
