Electric Violin
Domorád, Petr ; Bělohlávek, Jan (referee) ; Zdařil, Zdeněk (advisor)
The bachelor thesis deals with the design of the new design of electric violins. The aim of the work is to break away from the stereotypes and traditional forms of baroque acoustic violins, which are in the design of electric violins often occur . Electric Violin therefore become a kind of substitute for classical violin , this may include a specific instrument , which allows to experiment with violin tones considerably richer . The new design of the shape electric violin should be ergonomically correct for easy violin , but interesting , new and unusual . When designing and manufacturing must be some part of classical violin left ( eg the shape of the neck or fingerboard ) . These parts may slightly vary because each said portion has a specific role to play violin . Proposal for violin based on the basic ergonomic features violin. From classical violin are left only parts which are to preserve functionality may change shape. Three into the protruding part of the body support a comfortable grip of instrument and mechanics, which is located at its ends , allows adjustability holding of instrument by violinist characters . Violin comply with rotational symmetry , which is an advantage , since the instrument can be used right-handed and left-handed. The proposal addresses the fact that the various components do not interfere with the violin ( eg potentiometers for volume and tone controls or instrument input cable for connecting the instrument to the apparatus ) . As these details when control may not see a violinist , but is usually controlled through hearing , are placed in the bottom of the hull of the violin , where playing the violin will not mind a useless way. The material used for the prototype of a violin is wood (possible combinations of various different types of wood for a better visual effect and to promote the curves of the body tools), which, after milling the surface treatment and paint several layers of lacquer . Components for attaching strings and adjustable drives are made of metal. Electronics, which is mounted inside the cavity of the tool body is bought, the additional component.

Design of Digital Piano
Sikora, Halina ; Chorý, Tomáš (referee) ; Sládek, Josef (advisor)
This master’s thesis deals with the design of a digital piano. This increasingly popular musical instrument offers possibilities not available in an acoustic piano (outputting sound into headphones, utilizing sample libraries, recording, use of sheet music in digital form and more). From technical standpoint, it attempts to closely mimic the qualities of traditional instruments, both in its tactile feedback and sound quality. The aim of this work was to design a solution which would starkly differentiate from the very conservative classical design without being overly extravagant. The main focus is therefore on aspects of visual appearance, with emphasis on ergonomics, and an outline of the technical solution.

Experimental Software Musical Instrument on Android Platform with Ability to Control Parameters by Moving Phone
Barák, Filip ; Kavan, Jan (referee) ; Dlouhý, Dan (advisor)
The purpose of this thesis is to create an application on the Android platform, which is characterized by an unconventional way of controlling the main melodic signal – by moving the phone. At the same time, the application allows you to edit the audio parameters on your phone's display. Another important feature is the ability to compose and later play chords, or other simple harmonies. The application design is preceded by a theoretical introduction, where I briefly analyze the musical terms and parameters of the application that I developed in the Android studio, Java language. Furthermore, I mention the actual methods of application implementation including code samples.

Musical Signal Synthesis on Android
Mikulík, Jan ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
The main task of this thesis is to design and implement new synthesizer on mobile platform under Android. The synthesizer generates three types of signals - sine, sawtooth and square. Two types of filters can be applied, low pass and high pass, and their cut-off frequency can be controlled. For the sound interpretation, an AudioTrack API was used. The synthesizer is controlled by zones, where one zone equals one tone. Zones can be selected by the user. For this synthesizer, a simple user interface was created.

Electronic Drum Control Module
Doležal, Karel ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This paper deals with development and construction of an electronic drum module. The purpose of the device is to capture signals from an electronic drumkit and to produce sound accordingly. Firstly, a protoype with no sound output is constructed to demonstrate an ability to capture input signals. Based on its function, parameters for a final device are determined. Then, electronic component selection and design of printed circuit boards is described with an aim to maximalize polyphony and minimize latency of the sound generator. After that, firmware with software mixing algorithm is designed. Lastly, testing and measurement of real device parameters is performed.
