Unreal instruments
Modus uses our latest research in collision modelling to connect acoustic elements together. Strings, plates, springs and rattles collide, literally, in algorithmic air to generate tones that resonate and react just like they would outside the virtual realm. These elements are combined in different ways to create three types of instruments.

Connected Strings
Each voice has up to four connected strings which can be plucked or act as resonators. The strings are connected by either rattles that give collision effects as the strings vibrate, or nonlinear springs. Physical parameters control the decay, mass and harmonic content along with individual semitone and fine tuning controls.

Strings connected to a Plate
This model has two strings connected to a plate using nonlinear connections that can either be rattles or springs. These strings are retuned on-the-fly to give 6 octaves of monophonic or duophonic sound. The plate can act as a soundboard by varying its decay, mass and fundamental frequency. These, along with the connection controls, can all be changed in real-time.

Driven Plates
A driver signal is used to excite the top plate, which is connected to the bottom plate with two nonlinear connections. This driver can be a polyphonic sawtooth or sine wave, or a multi-striking hit for percussive effects. There is also an option to use a single plate connected to ground.
