Your Model MF-107 FreqBox™ is a rugged, professional-quality instrument, designed to be equally at home on stage or in the studio. Its great sound comes from the state-of-the- art analog circuitry, designed and built by the folks at Moog Music in Asheville, NC. Your MF-107 FreqBox is a direct descendent of the original modular Moog® synthesizers. It contains several complete modular synth functions: a voltage-controlled oscillator (VCO) with variable waveshape, capable of being hard synced and frequency modulated by the audio input, and an envelope follower which allows the dynamics of the input signal to modulate the frequency of the VCO. In addition the amplitude of the VCO is controlled by the dynamics of the input signal, and the VCO can be mixed with the audio input. All performance parameters are voltage-controllable, which means that you can use expression pedals, MIDI-to-CV converter, or any other source of control voltages to 'play' your MF-107. Control voltage outputs mean that the MF-107 can be used with other moogerfoogers or voltage controlled devices like the Minimoog Voyager® or Little Phatty® synthesizers. While you can use it on the floor as a conventional effects box, your MF-107 FreqBox is much more versatile and its sound quality is higher than the single fixed function "stomp boxes" that you may be accustomed to.

  • The 1-Bit Instrument: the Fundamentals of 1-Bit Synthesis
    BLAKE TROISE The 1-Bit Instrument The Fundamentals of 1-Bit Synthesis, Their Implementational Implications, and Instrumental Possibilities ABSTRACT The 1-bit sonic environment (perhaps most famously musically employed on the ZX Spectrum) is defined by extreme limitation. Yet, belying these restrictions, there is a surprisingly expressive instrumental versatility. This article explores the theory behind the primary, idiosyncratically 1-bit techniques available to the composer-programmer, those that are essential when designing “instruments” in 1-bit environments. These techniques include pulse width modulation for timbral manipulation and means of generating virtual polyph- ony in software, such as the pin pulse and pulse interleaving techniques. These methodologies are considered in respect to their compositional implications and instrumental applications. KEYWORDS chiptune, 1-bit, one-bit, ZX Spectrum, pulse pin method, pulse interleaving, timbre, polyphony, history 2020 18 May on guest by http://online.ucpress.edu/jsmg/article-pdf/1/1/44/378624/jsmg_1_1_44.pdf from Downloaded INTRODUCTION As unquestionably evident from the chipmusic scene, it is an understatement to say that there is a lot one can do with simple square waves. One-bit music, generally considered a subdivision of chipmusic,1 takes this one step further: it is the music of a single square wave. The only operation possible in a -bit environment is the variation of amplitude over time, where amplitude is quantized to two states: high or low, on or off. As such, it may seem in- tuitively impossible to achieve traditionally simple musical operations such as polyphony and dynamic control within a -bit environment. Despite these restrictions, the unique tech- niques and auditory tricks of contemporary -bit practice exploit the limits of human per- ception.

However, certain types of loads produce currents and voltages with frequencies that are integer multiples of the 50 or 60 Hz fundamental frequency. These higher frequencies are a form of electrical pollution known as power system harmonics. Power system harmonics are not a new phenomenon. In fact, a text published by Steinmetz in 1916 devotes considerable attention to the study of harmonics in three-phase power systems. In Steinmetz’s day, the main concern was third harmonic currents caused by saturated iron in transformers and machines. He was the first to propose delta connections for blocking third harmonic currents. After Steinmetz’s important discovery, and as improvements were made in transformer and machine design, the harmonics problem was largely solved until the 1930s and 40s. Then, with the advent of rural electrification and telephones, power and telephone circuits were placed on common rights-of-way.

  • A Look Into the Development and Presence of Early Video Game Music in Popular Culture
    Wesleyan University The Honors College 8-Bit Heroes: A Look into the Development and Presence of Early Video Game Music in Popular Culture by Anthony Martello Class of 2010 A thesis (or essay) submitted to the faculty of Wesleyan University in partial fulfillment of the requirements for the Degree of Bachelor of Arts with Departmental Honors in Music Middletown, Connecticut April, 2010 2 8-Bit Heroes: A Look into the Development and Presence of Early Video Game Music in Popular Culture Introduction Video games are more popular than ever. Youth spend their days with their eyes glued to the video screen spending countless hours gaining unimaginable power and prowess in simulated worlds. Video games are often written off as just another example of simple popular culture. But as many other art forms possessed similar conceptions in their beginnings, video games may one day be considered a new serious art medium. Though there are many key aspects to the popularity of video games, most of them at base level are visual by nature. However, when it comes to relating a character or environment in a virtual world to a person in the real world, audio is a key component in empathizing with the gamer. The different sound effects in a game and the background music to each setting present the simulated world in a more defined environment that the player can relate to. For example, dark ominous music can represent impending danger, while upbeat cheery music allows the gamer to relax in safety. Not only does music give these video game worlds a sound environment, but it also creates a sense of feeling and emotion within the gamer.

  • Chapter 8 Spectrum Analysis
    CHAPTER 8 SPECTRUM ANALYSIS INTRODUCTION We have seen that the frequency response function T( j ) of a system characterizes the amplitude and phase of the output signal relative to that of the input signal for purely harmonic (sine or cosine) inputs. We also know from linear system theory that if the input to the system is a sum of sines and cosines, we can calculate the steady-state response of each sine and cosine separately and sum up the results to give the total response of the system. Hence if the input is: k 10 A0 x(t) Bk sin k t k (1) 2 k1 then the steady state output is: k 10 A0 y(t) T(j0) BT(jk k )sin k t k T(j k ) (2) 2 k1 Note that the constant term, a term of zero frequency, is found from multiplying the constant term in the input by the frequency response function evaluated at ω = 0 rad/s. So having a sum of sines and cosines representation of an input signal, we can easily predict the steady state response of the system to that input. The problem is how to put our signal in that sum of sines and cosines form. For a periodic signal, one that repeats exactly every, say, T seconds, there is a decomposition that we can use, called a Fourier Series decomposition, to put the signal in this form. If the signals are not periodic we can extend the Fourier Series approach and do another type of spectral decomposition of a signal called a Fourier Transform.
