A Framework for Embedded Digital Musical Instruments
A Framework for Embedded Digital Musical Instruments Ivan Franco Music Technology Area Schulich School of Music McGill University Montreal, Canada A thesis submitted to McGill University in partial fulfillment of the requirements for the degree of Doctor of Philosophy. © 2019 Ivan Franco 2019/04/11 i Abstract Gestural controllers allow musicians to use computers as digital musical instruments (DMI). The body gestures of the performer are captured by sensors on the controller and sent as digital control data to a audio synthesis software. Until now DMIs have been largely dependent on the computing power of desktop and laptop computers but the most recent generations of single-board computers have enough processing power to satisfy the requirements of many DMIs. The advantage of those single-board computers over traditional computers is that they are much smaller in size. They can be easily embedded inside the body of the controller and used to create fully integrated and self-contained DMIs. This dissertation examines various applications of embedded computing technologies in DMIs. First we describe the history of DMIs and then expose some of the limitations associated with the use of general-purpose computers. Next we present a review on different technologies applicable to embedded DMIs and a state of the art of instruments and frameworks. Finally, we propose new technical and conceptual avenues, materialized through the Prynth framework, developed by the author and a team of collaborators during the course of this research. The Prynth framework allows instrument makers to have a solid starting point for the de- velopment of their own embedded DMIs. -

Staying Connected
Staying Connected Why you need to stay connected Feeling connected is essential for our physical and mental wellness. Physical distancing during COVID-19 limits all of our social engagements - dinners at Grandma's, nights out with friends, and catching a local concert or sporting event. This new normal also greatly reduces our simple day-to-day interactions like holding a door open for a stranger or small talk with a shop owner. While it is more difficult to remain feeling connected to our extended family and friends during this time, it is possible. To make up for these social interactions, it's important to reach out using technology to Social Connection Ideas connect with our family and friends more frequently. Here are some ideas for you to connect virtually with your loved ones using the apps: How to stay connected Celebrate holidays, birthdays, and other special moments virtually in a video call There are many ways to connect with your Recruit a loved one to help support your social circle while you stay safely at home. child with their online learning program Apps like FaceTime, WhatsApp, Facebook Host a virtual event for friends - teach Messenger, and Zoom allow you to group them how to make your favourite recipe, video chat with your family and friends. play live music, or share a story Schedule regular family suppers via group Messenger Kids is another free app that video chat to enjoy meals together allows your children to connect with friends Host an online talent show, dance party, and family (while parents maintain full or karaoke singalong control of their children's contact list). -
Putting Information at Your Fingertips with Dashboard | 133 My New Mac, Snow Leopard Edition (C) 2009 by Wallace Wang Adding Widgets to Dashboard
Putting Information at Your Fingertips 15 with Dashboard While using your Macintosh, you may suddenly need to look at a calendar, a clock, a weather forecast, or a calculator. Rather than reach for a paper calendar, a clock, a newspaper weather forecast, or a pocket calculator, you can use your Macintosh to display these items using a program called Dashboard that comes with every new Macintosh. Dashboard provides a variety of simple programs, called widgets, that you can pop on the screen at any time and make disappear at a moment’s notice. You can be typing in a word processor, run Dashboard to view a calendar or sport score, and then shove Dashboard out of the way again to keep working in your word processor. If you need information at your fingertips, you’ll find Dashboard a valuable asset when doing anything with your Macintosh. Project goal: Learn to use and modify Dashboard to view different types of widgets on the screen. What You’ll Be Using To learn how to display simple programs on the screen, you’ll be using the following: > The Dock > Dashboard > The Safari web browser My New Mac, Snow Leopard Edition (C) 2009 by Wallace Wang Starting Dashboard The Dashboard program starts and manages miniature programs called widgets. A widget performs a single function, such as displaying a calendar or calculator on the screen. Every time you want to use a widget, you have to start Dashboard. You can start Dashboard in three ways: > Press F12. > Click the Dashboard icon on the Dock. > Double-click the Dashboard icon stored in the Applications folder. -
