But what really makes the Mac what it is—an easy-to-use and highly customizable personal computer—is the system software. The system software creates the desktop, lets you organize your files in folders, and gives you capabilities—such as cutting and pasting text and graphics—that work in virtually any Mac program. In this chapter, we describe the basic components of the Mac system soft- ware. You’ll also find advice on system software installation and modification. 76 Chapter 3: System Software Contributors Contents Sharon Zardetto The Operating System.....................................................77 Aker (SZA) is the chapter editor.

Your Mac comes with a lot of other fascinating software, too — and the flood doesn’t stop: Every few months, Apple releases some Updater or other, which you’re supposed to know about, get, and install. Your Mac even comes with some software the Installer doesn’t install; those additional programs get left behind on the original System software disks, or dumped into an unex- plained folder on your hard drive called Apple Extras. All of it is worth know- ing about. 181 182 Part I: System Software Revealed THE SYSTEM FOLDER FOLDERS System 7 greatly reduced the cluttered, no-nested-folders setup of System 6. System 7 introduced a set of standard folders within the System Folder (see Figure 5-1): one each for Extensions (INITs), Control Panels, Preferences, Fonts (in System 7.1 and later), Apple Menu Items, PrintMonitor Documents, Startup Items, Shutdown Items (System 7.5), and Launcher Items (System 7.5). Depending on your model and System version, you may also have folders that collect things such as Speakable Items and Control Strip Modules.

Visually Impaired, Physically Handicapped, and Hearing Impaired are areas of exceptionality that will be considered. Software, examples of ongoing research, current projects, and various commissions in action will be explored as part of the presentation. New Controllers will be video explained. Presentation Envision Possibilities! Bias Dictates Actions! Look to our students’ exceptionalities as opportunities for advancement. Many students with disabilities on college campuses do not realize their potential, as they are never seen. At times we tend to focus of the generic status quo we see each day. Music Technology assists in providing opportunities for music participation, whether on campus, or through distance education programs. Music Technology is doing wonders for individuals with exceptionalities and providing opportunities for performance and participation in both distance education and classroom music activities.

  • 1 VOICE CONTROLLED MUSIC SEQUENCER Interactive Qualifying
    VOICE CONTROLLED MUSIC SEQUENCER Interactive Qualifying Project Report completed in partial fulfillment of the Bachelor of Science degree at Worcester Polytechnic Institute, Worcester, MA Submitted to: Professor Bianchi Ma’at Ford __________________________ Victoria Valcour __________________________ (date of submission) __________________________ 1 Abstract This project served as a proof-of-concept to determine the validity of a voice-controlled music sequencer. Working with Digital Performer and Dragon Dictate software, the project explored the history of voice-recognition technology, and the feasibility of this technology within a music sequencing environment. 2 Table of Contents Executive Summary ……………………………………………………………………………... 4 Introduction ………………………………………………………………………………...……. 6 Methodology …………………………………………………………………………………….. 8 Results ………………………………………………………………………………………….. 12 Appendix A …………………………………………………………………………………….. 14 Works Cited ……………………………………………………………………………………. 17 3 Executive Summary The objective of this IQP was to develop a voice-controlled music sequencer prototype that would serve as a proof-of-concept to determine the validity of developing a more sophisticated model. A voice-controlled sequencer would allow the user to initiate and realize a number of editing and data manipulation procedures through voice commands. Execution of these commands will help facilitate the preparation of large and involved music sequences that have traditionally required time intensive editing strategies. The speech-recognition technology would allow users to easily alter properties of songs without having to use keystrokes associated with their desired command. Voice-activated music sequencers are also necessary for increasing accessibility for disabled users, who experience difficulties utilizing traditional sequencers due to visual or other physical impairments. Ultimately, a voice controlled music sequencer will make the editing procedures more representative of the interaction that occurs between a conductor and a live acoustic orchestra.
