The Innovation of Oscillators in Rhodes pianos
Prokop, Šimon
For decades, the enchanting sounds of mechanicalelectric keyboards have been a source of inspiration. However, there has been a lack of significant innovation in their mechanical components for many years. This paper deals with development of oscillators for mechanical-electric keyboard instruments, specifically focusing on innovations in a frequency spectrum due to modifications in the geometry of mechanical parts, variations in materials, sensing position and hammer strike position. Drawing from the original oscillators of Rhodes Mk7 instrument, new virtual models were created using software SolidWorks and subsequently analyzed using software Ansys. These models were then physically fabricated and subjected to examinating. The final assessment involved comparing the frequency spectra of the upgraded assemblies with the original assemblies and analyzing resulting data.

Application for Demonstrating Principles of Hybrid Sound Synthesis
Prokop, Šimon ; Indrák, Michal (referee) ; Schimmel, Jiří (advisor)
The master thesis deals with the description and application of the main principles of sound signal generators contained in hybrid synthesizers. The individual methods and ways of generating audio signals were first studied and based on the theory, scripts were then created in Matlab to demonstrate the principle functions of the individual generators. Based on the logic of these scripts, a polyphonic hybrid synthesizer was created in VST3 format in the C++ language with the JUCE framework. The synthesizer allows the user to choose between basic readout methods Wavecycle and Wavetable, audio signal filtering or oversampling of the overall signal process.

The Innovation of oscillators in mechanical-electrical keyboard instruments
Prokop, Šimon ; Buzzi, Mario (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with innovations of oscillators of mechanical-electric keyboard instruments, especially from the perspective of frequency spectrum innovations. On the basis of the original oscillators of the Rhodes Mk 7 instrument, innovative virtual models of these oscillators were created in SolidWorks, which were subsequently analyzed in Ansys. Subsequently, these assemblies were physically fabricated and tested. In the final evaluation, the signal spectra of the upgraded assemblies were compared with the original tone and the analyzed data. The theoretical part of the thesis also discusses basic signal processing methods and describes methods for evaluating sound perception using psychological acoustics.
