Abstract: An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display; a first memory storing audio files for playback when the playback is triggered by a signal received from a pad; and one or more processors coupled to the display and the memory. The processors are configured receive an instruction to transfer a set of samples. The set of samples is associated with a priority-instruction and includes a first subset of samples and a second subset of samples. The processors are also configures to transfer the first subset of samples from a second memory to the first memory based on the priority-instruction before transferring the second subset of samples and to transfer the second subset of samples from the second memory to the first memory.

Abstract: Systems and methods for generating a graphical representation of audio-file playback during playback manipulation are provided. The system may include a processor that performs a method including displaying a waveform during audio-file playback by scrolling the waveform from a right to a left portion of a display. The method includes receiving a command to manipulate the audio-file playback and displaying a first half of the waveform corresponding to the manipulated audio-file playback until a command is received to resume the audio-file playback. The first half of the waveform is a portion of the waveform adjacent to a horizontal or vertical axis. The method includes simultaneously displaying a second half of the waveform and displaying the first half of the waveform corresponding to the manipulated audio-file playback. The second half of the waveform is on an opposite side of the axis from the first half of the waveform.

Abstract: An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display, a memory storing audio files for playback when the playback is triggered by a signal received from a pad, and one or more processors coupled to the electronic display and the memory. The processors are configured to play the audio files when the playback is triggered and display, on the display, a user interface for an application. The user interface for the application includes a list of available trigger sources. The processors are also configured to receive an instruction to select an available trigger source and display, on the display, a list of available drum kits to associate with the available trigger source. The processors are also configured to display images of the available drum kits in response to receiving an instruction to select an available drum kit.

Abstract: An electronic percussion device has a plurality of touch sensitive pad, an array of lighting elements disposed adjacent each pad, and a virtual display of the currently selected kit. The light array provides the user with immediate visual cue about the status and capabilities of the sound selections, without having to interrupt the user's performance. The user can color code and animate the illumination pattern of each light array so that, from a distance, the user is visually reminded what sounds are assigned to each pad, when sound associated with particular pad is currently playing, when playback of a sound associated with a pad is about to end.

Abstract: An electronic percussion device has a plurality of triggerable actuators, in the form of any of pads, external trigger inputs or foot switches, that may be organized into synchronized groups, and has an operational mode in which triggering of any actuator within the synchronized group initiates playback of audio events or execution of control functions associated with other of the actuators within the synchronized group in one of multiple different synchronization orders, e.g. one at a time, all simultaneously, random or in a predefined or user-defined consecutive order.

Abstract: Systems and methods for generating a visual color display of audio-file data are provided. The system includes a processor that performs a method including receiving audio-file data; generating filtered-audio data by processing the audio-file data by frequency-band filters. The frequency band filters have different frequency bands. The method includes generating one or more waveforms corresponding to the filtered-audio data and displaying the waveforms superimposed in unique color relative to one another. The method includes downsampling the waveforms. The method includes processing the waveforms through an envelope detector. The method includes processing the waveforms through an expander and applying a gain factor. The waveforms have transparency levels at sections that are proportional or inversely proportional to amplitudes at the sections.

Abstract: An electronic drum with active crosstalk detection includes a first vibration transducer configured to generate a first signal in response to a strike to the electronic drum, and a second vibration transducer configured to generate a second signal in response to vibrations in a mount coupled to the electronic drum. A circuit compares an amplitude of the first signal and an amplitude of the second signal within a predetermined time, and determines whether the signal was generated by crosstalk or an actual drum hit based on various criteria.

Abstract: A guitar pedalboard for creating a loop includes a touch screen display for displaying a plurality of tracks of a loop. The touch screen display can be used to adjust a parameter of each track, and the loop. A plurality of footswitches corresponding to the plurality of tracks can be used to independently record and play each track of the loop.

Abstract: A standalone DJ console includes onboard audio data, user interface, processing engine and mixing module that enable multiple virtual audio players operating under the control of the processor to be mixed by virtual mixing processes into two different audio signal streams routable to different outputs of the console to provide two different audio streams to two separate spaces. The user interface is designed with a virtual display and parallel sets of controls which enable virtual representations of audio waveforms to be scrolled relative to an axis of time above the respective set of controllers used to manipulate the audio signal stream.
