In Computer Music, a practical approach of many Digital Musical Instruments is to separate the gestural input stage from the sound synthesis stage. While these instruments offer many creative possibilities, they present a strong rupture with traditional acoustic instruments, as the physical coupling between human and sound is broken. This coupling plays a crucial role for the expressive musical playing of acoustic instruments; we believe restoring it in a digital context is of equal importance for revealing the full expressive potential of digital instruments. This paper first presents haptic and physical modelling technologies for representing the mechanoacoustical instrumental situation in the context of DMIs. From these technologies, a prototype environment has been implemented for both designing virtual musical instruments and interacting with them via a force feedback device, able to preserve the energetic coherency of the musician-sound chain.
