GUItar is a graphical environment for graph visualization, editing, and interaction, that specially focuses in finite automata diagrams. The application incorporates mechanisms to facilitate the editing of these graphs. It also provides a style manager that allows the creation of rich state and arc styles to be used in the drawing of its objects. This style manager allows the system to cope wit...

The RANGE guitar is a minimally-invasive hyperinstrument incorporating electronic sensors and integrated digital signal processing (DSP). It introduces an open framework for autonomous music computing eschewing the use of the laptop on stage. The framework uses an embedded Linux microcomputer to provide sensor acquisition, analogto-digital conversion (ADC) for audio input, DSP, and digitalto-an...

Source-filter models are a well-established technique for the analysis and synthesis of many acoustic signals, including musical instruments. When applied to the task of modeling plucked-string instruments, these models provide a clear analog to the physical phenomena incurred with exciting the string; that is, an impulsive-like force from the performer excites the resonant behavior of the stri...

This paper presents a computational model of fingering for string instruments, based on a graph search approach. The implemented fingering model, which accounts for the bio-mechanical constraints of the performer’s hand, is interfaced with a physical model of the classical guitar, which exploits the fingering to compute some sound synthesis parameters. The output of the system is validated agai...

Physical modeling allows realistic guitar synthesis incorporating many expressive dimensions commonly employed by guitarists, including pluck strength and location, plectrum type, hand damping and string bending. Often, when a physical model is used in performance, most control dimensions go unused when the interface fails to provide a way to intuitively control them. Techniques as foundational...

This paper attempts to use an off-the-shelf anaphora resolution (AR) system for Bengali. The language specific preprocessing modules of GuiTAR (v3.0.3) are identified and suitably designed for Bengali. Anaphora resolution module is also modified or replaced in order to realize different configurations of GuiTAR. Performance of each configuration is evaluated and experiment shows that the off-th...

In this paper we address the problem of mapping guitar music score into one of possible alternative fingering sequences on the fretboard grid. We use dynamic programming (DP) to model the decision process of a guitarist choosing the optimal fingering sequence. To estimate the DP cost functions based on examples of guitar fingering transcriptions (tablatures) we developed an original method name...

The market for digital modeling guitar amplifiers requires that the digital models behave like the physical prototypes. A component of the iconic Fender Bassman guitar amplifier, the tone stack circuit, filters the sound of the electric guitar in a unique and complex way. The controls are not orthogonal, resulting in complicated filter coefficient trajectories as the controls are varied. Becaus...

Amplified guitars with pickups tend to sound ’dry’ and electric, whether the instrument is acoustic or electric. Vibration or pressure sensing pickups for acoustic guitars do not capture the body vibrations with fidelity and in the electric guitar with magnetic pickups there often is no resonating body at all. Especially with an acoustic guitar there is a need to reinforce the sound by retainin...

Platforms for mobile computing and gesture recognition provide enticing interfaces for creative expression on virtual musical instruments. However, sound synthesis on these systems is often limited to sample-based synthesizers, which limits their expressive capabilities. Source-filter models are adept for such interfaces since they provide flexible, algorithmic sound synthesis, especially in th...
