PortaMento is Jesper Hahn, born 1976 in Denmark.
The project came into existence in 1997, inspired by the great artists of the time and born out of the desire to make melodic tracks with a slighly darker twist. The very first tracks were made on a Roland W30 12bit sampler workstation using the built in midi sequencer. All composing was done using a tiny 240×62 dot monochrome display. This was soon replaced by a software sequencer and a growing sonic arsenal, at one time counting more than 20 vintage analog synths.
