Using SD Cards
The SD card slot option provides additional functionality to the Millennium Carillon. The option board the slot is mounted to contains additional memory that holds pre-recorded sound files. The slot will accept SD cards formatted on a PC (FAT32 format) to which you have copied MP3 files. These files can also be played from the carillon when named as described below.
Provided files on the user card
- 6491 Amazing Grace -
- 6492 Amazing Grace (March off)
- 6493 The Battle is Over
- 6494 Goin’ Home
- 6495 I’ll Fly Away
Add your selections to the SD card
Remove card from carillon
Removing the name plate on the lower right of the front panel provides access to this slot (if installed). If a card is already in the slot, push on it to eject and then remove it. After the steps below, reinstall the card with the contacts down.
Format additional cards
Cards as large as 8GB have been tested to work with the system. The card should be formatted as FAT32 using your PC. Insert a new card, right click, select Format, and verify that it is FAT32 and re-format if it is not.
Extract MP3 file from CD
There are many free solutions that can be downloaded from the internet. We have had success using a Windows program called CDex Version 1.79 (CD extraction). The official website is cdex.mu but if you have issues downloading and getting the program to run, call us for downloading instructions.
The CDex program will create directories in your Music folder for the extracted files. Make the following settings changes so that you can name the files as you extract them:
- Remove the track number from filename:
options > settings > Directoies & files delete %7- from Filename Format
- Set encoding parameters (in this order, not from top to bottom of screen)
options > settings > Encoders select Lame MP3 Encoder Quality = Very High Quality VBR Method = Disabled Bitrate Min = 128 kbps Mode = Mono
The MP3 file’s left channel goes to the outside speakers and the right channel plays inside. If the file is to play both inside and outside, create a mono file. To prevent music with significant low frequency content (modern pop music or pipe organ selections) from damaging the outside horns, we recommend that you prepare full range music files so that all of the audio is on the right channel, so that it plays inside only.
Mixing to mono can be done with CDex. For Mixing and muting one channel or the other, you need to use a program such as Audacity. For best results, extract the tracks in CDex as WAV files, edit/mix the channels in Audacity, then export the track using an MP3 plugin (not supplied with the initial download).
- Insert audio CD into the drive on your PC
- Edit the Titles column for each track to start with a four digit number between 6000 and 6495
- Select the tracks you want to encode into MP3 files (ctrl-A to select all)
- Press F9 to extract the files
- Eject the disc and repeat for additional discs
MP3 file naming requirements
Make sure each 6000 number used is unique on the card. The characters after the hyphen will be ignored by the carillon system. The 6000 number can be used for any four digit selection code in the automatic or manual modes.
Copy MP3 file to SD card
CDex extracts CD files to your Music folder. Insert the SD card from the carillon into your PC's cardslot (or external adapter). Open the folder for the card and drag the files from your Music folder onto the memory card.
Before you remove the card from the computer, select it in File Explorer and Eject it so that the data files are all closed properly.
Install the card
Removing the name plate on the lower right of the front panel provides access to this slot (if installed). If a card is already in the slot, push on it to eject and then remove it. Install the card with the contacts down.
Use the Play Selections menu to test the selections you have copied. Whenever a four digit selection code is flashing, you can simply enter the 6000 number for the selection you want to play from the SD card.
Easier use and additional functionality can be experienced using the SD card with the Management Suite software.
