Practice keyboard bell samples

One way to get bell sounds for a MIDI carillon practice keyboard is to install a sample player on a Mac or PC and add a USB MIDI adapter to connect the keyboard.

Hardware requirements

• Keyboard, mouse, display if computer is not a laptop
• USB Midi interface cable
  • Roland UM-ONE is recommended - from Sweetwater - from Amazon
    • UM-ONE USB Drivers available for many OS versions from Mac 10.4 and Windows XP to Mac 10.13 and Windows 10.
• Headphones or amplified monitor speaker

Sample player software

Plogue Sforzando

Download Sforzando for OS X or Windows from Plogue's download page

Sforzando requires either a

• Mac with OSX/MacOS (10.6.8 & up). A used Mac Mini will run it very well
• or Windows PC (Windows 7 and up)

Sample players for Linux

LinuxSampler supports the SFZ file format used below. Usage is beyond the scope of this article, but we have loaded the samples into it to check compatibility. The easiest way to make it work is using a graphical plug-in host such as Carla. If you have audio experience in Linux, you should be able to get it to work. If you are a beginner wanting to experiment with Linux audio, we suggest you start with a distribution called KXStudio. It works well on old PCs with good sound cards.

Save the file as lurie.sfz in the lurie folder to which the samples were unzipped. You should check to see if the editor added .txt to the end, and delete it if the file name does not end with only .sfz

Load the file into Sforzando

1. Start Sforzando
2. Drag the lurie.sfz file onto the Sforzando window.
3. The bells should play when you click on the keys of the on screen keyboard
4. If you have connected and configured your MIDI interface, Open sforzando preferences from the menu, select your MIDI input and audio output
5. In Sforzando's File menu, select save as and enter Practice Lurie

GCNA Members Only Samples

2012 Ronald Barnes Memorial Scholarship winner Ed Herrmann created high-quality recordings of the carillon bells at the University of Chicago's Rockefeller Memorial Chapel. These recordings are available to all GCNA members, and are useful to provide bell sounds for the carillon practice keyboard.

Requires a GCNA Membership to access the download pages below.

Download Chicago samples

Download the Chicago samples from the GCNA members web page

1. go to the Members area of the GCNA website
2. enter your user name and password for access
3. right click each bell note link to save link as
4. copy the downloaded .wav files from your downloads folder to a new folder named samples

Save the file as chicago.sfz in the samples folder

Load the file into sforzando

1. Start sforzando
2. At the top left of the app, click INSTRUMENT and then Import, navigate to chicago.sfz and open it
3. The bells should play when you click on the keys of the on screen keyboard
4. If you have connected and configured your MIDI interface, Open sforzando preferences from the menu, select your MIDI input and audio output
5. In sforzando's File menu, select save as and enter Practice Chicago

Advanced

Reducing latency in Windows

Windows 10 should be optimized for audio. Out of the box, it will have an annoying delay after playing a key. Focusrite has an excellent guide to Optimizing Your PC for Audio on Windows 10.

Auto-boot headless operation

It would be nice to power on the computer, then power on the keyboard and in a few seconds be able to practice without fooling around on a screen with a mouse and keyboard. Using one of these methods, you should be able to set up your computer to make it so.

For this to be possible, you should dedicate the computer for this purpose and not connect it to the internet after setup. Do not follow these procedures if you use the computer for other purposes.

Sforzando should be set up the way you want it, then from the Sforzando File menu, select Save as default. Every time Sforzando is started it will use this configuration.

Mac

Setup

From the Apple menu choose System Preferences and make the following changes

• Desktop and Screen Saver: Screen saver set to Start after Never.
• Disable software updates.
• Privacy and security: uncheck Disable automatic login.
• Notifications: Set alert style to None for all notifications
• Energy Saver: Computer sleep set to Never. Check Start up automatically after a power failure (on newer versions, we'll have to press the button)
• App Store: Uncheck all checking, download and install options
• Users & Groups:
  • Select Login Options then Set Automatic login ON for the user account and enter the password
  • Select the user account and Login Items. Click the Plus Sign (add) button at the bottom of the window
    • Navigate to the Applications folder and select Sforzando

Usage

Press the button on the Mac to power it on. The software should load and be ready to play in under a minute.

Press the button again to safely shut down the Mac.
