A computer-implemented method including generating a user interface implemented on a touch-sensitive display configured to generate a virtual dual flywheel system for modulating a lifecycle of a musical note or chord. The dual flywheel system (DFS) includes a first VFS and a second VFS, where the first virtual flywheel system series connected to the second virtual flywheel system such that an output of the first virtual flywheel system is coupled to an input of the second virtual flywheel system. Upon receiving a user input on the user interface, the dual flywheel system determines a virtual momentum for the first virtual flywheel based on the user input and a predetermined mass coefficient of the first virtual flywheel system, and determines a virtual momentum for the second virtual flywheel based on the virtual momentum of the first virtual flywheel system and a predetermined mass coefficient of the second virtual flywheel.
