Different aspects of the invention implement a multimedia transporter system configured to accommodate a disassembled modular piano keyboard, and at the same time, configured to enhance the sound and user experience once the modular piano keyboard is assembled and played. Thus, the system comprises a multimedia transporter and a modular piano keyboard, optionally with pedals. A corresponding method is implemented in a multimedia transporter, as well as in the system, in addition to a computer program and a computer-readable medium, both comprising instructions that, once executed on a processor, carry out the method in the multimedia transporter system.

Music may be generated by electronically applying one or more functions that change a compositional nature of a musical input in a first tonality to generate a musical output in a second tonality in response to an event in a videogame. Data corresponding to the output melody may be recorded in a recording medium.

An audio processing method, apparatus, and system. The processing method is applied to a sound pickup, and the sound pickup is connected to a controller. The method comprises: receiving timbre instruction information sent by a controller (S101); and analyzing the timbre instruction information, and carrying out, according to the timbre instruction information, timbre processing on audio that is picked up, wherein the timbre instruction information comprises timbre addition instruction information and/or timbre change instruction information (S102). The selection of various timbres in an audio processing process is enabled, the requirement for the integration of the related functions is met, and user experience is improved.

Tonal musical instruments configured for outdoor installation are disclosed. The tonal musical instrument may comprise a support post, wherein the support post is configured for attachment to an outdoor surface, at least one a non-vibrating guard, a metal plate tuned to produce at least one note on a musical scale when struck by a user, and one or more fasteners securing the at least one non-vibrating guard and the metal plate to the support post.
