Abstract: A musical apparatus including a first audio looping device for being electrically coupled to a second audio looping device is provided. The first audio looping device being configured to receive a first audio signal from a first musical instrument and to store the first audio signal. The first audio looping device being further configured to playback the stored first audio signal as a first loop a first number of times. The first audio looping device being further configured to transmit synchronization information to the second audio looping device that stores a second audio signal and that plays back the stored second audio signal as a second loop a second number of times. The synchronization information enabling the first loop and the second loop to be synchronized with one another during playback.

Abstract: An idler wheel assembly, for example a rear idler wheel assembly, for a snowmobile and includes at least one cross-member that permits load transfer and possible load damping as between a pair of rear idler wheels. The cross-member may be configured to transfer lateral loads, bending loads and other types of loads between the idler wheels. The cross-member is arranged between the wheels in such a manner that it is free to rotate with the idler wheels without interference to or from other structure of a skid frame assembly of the snowmobile. In one embodiment, each idler wheel includes a cross-member that extends inward to connect to the other wheel.

Abstract: A snowmobile chassis includes dual panels that form a lighter weight and stronger tunnel preferably without the need for structural doublers, plates or other attachable reinforcement devices. The dual panels take the form of inner and outer panels coupled together with selective gaps or spaces located between the panels. The gaps laterally separate the panels and may be continuous and take a variety of shapes as defined by each panel's configuration. The arrangement of the gaps may advantageously define a desired structural load path through the tunnel, increase a section modulus with respect to a centerline of the tunnel, and reduce an overall weight of the tunnel as compared with conventional tunnels that utilize added reinforcement devices.

Abstract: The top wall of a snowmobile tunnel, which accommodates the endless drive track of the snowmobile, is provided with recesses at locations corresponding to the path followed by studs carried by the endless track. The rear of the tunnel is connected to a molded rear member having a pattern of recesses matching that of the top wall of the tunnel. In yet another aspect of the invention, a heat exchanger for cooling engine coolant may be provided at the rear of the tunnel. The heat exchanger may be mounted to and partially spaced from the molded rear member. The heat exchanger may bear rearwardly extending ridges with upwardly extending lip at the far end. In some embodiments, a channel is provided on the upper end of the heat exchanger to promote air and snow flow over the rearwardly extending ridges.

In another aspect of the invention, the rear of the tunnel is connected to a molded rear member. The rear member provides a downwardly curving back portion for the tunnel. The rear member may have a shape corresponding to that of the tunnel, e.g. having a pattern of recesses matching that of the top wall of the tunnel. In yet another aspect of the invention, a heat exchanger for cooling engine coolant may be provided at the rear of the tunnel. The heat exchanger may be mounted to and partially spaced from the molded rear member, thereby permitting snow thrown by the endless track to pass on both sides of the heat exchanger. In another aspect of the invention, a tunnel for a snowmobile may be narrower in the front than in the rear.
