A metronome includes a body, a sensor coupled to the body and a controller in communication with the sensor. The sensor is configured to detect one or more strikes by a user of the metronome. The controller is configured to receive a first user input to select a tap tempo mode, detect via the sensor a strike by the user on the body of the metronome, determine a tempo based on a plurality of strikes by the user. The controller is further configured to detect modulation of how the strikes are made to the body of the metronome and automatically adjust the tempo based on the detected modulation of the strike.

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.

An apparatus may be designed to enable a user to receive, record, display, edit, arrange, re-arrange, play, loop, extend, export and import audio and video data. The audio and video data to be organized as, for example, but not limited to, a song comprised of song parts. The song parts may be comprised of tracks, and each track may be comprised of one or more layers. The various methods and systems disclosed herein incorporate such data segmentation to enable the user to intuitively and hands-free record, arrange, and perform songs comprised of both sequential and parallel tracks. In this way, the looper may enable a musician to record and loop tracks for a song, arrange the tracks into song parts, and during the same session, transition the playback from one song part to another, all the while recording a track on top of the transitioning song parts.

An apparatus for facilitating control of midi-sequence generation is disclosed. The apparatus may include a midi-sequence module configured to store a plurality of main midi sequences, store a plurality of fill midi sequences, and playback a plurality of main midi sequences and the plurality of fill midi sequences. The apparatus can also include a first foot-operable switch configured to operate the midi-sequence module, an instrument input, and a looping means configured to record a plurality of signals received from the instrument input, generate a plurality of recorded loops associated with the plurality of recorded signals, store the plurality of recorded loops, and playback each of the plurality of recorded loops. The apparatus can also include a second foot-operable switch configured to operate the looping means.

A method of operating a UI for controlling a virtual musical instrument implemented can include receiving an input corresponding to a selection of a cell within a particular array of cells arranged in a sequential arrangement within a cell matrix, each array of the cell matrix assigned to MIDI notes associated with audio sample data stored in a computer-readable medium that, when triggered, causes the audio sample data to output corresponding audio, and each cell within its particular array of the cell matrix, in response to being selected for playback and upon being triggered to begin playback, causes the audio sample data corresponding to the cell's particular array to be played. The method further includes determining that the input's duration is above a threshold time and expanding a size of an array containing the selected cell and adjusting the adjustable parameter of the selected cell based on the input.
