Rodgers organs always transmit note data on channels 12 and up. There is usually a group of switches (pistons below the great manual) that enable lower MIDI channels when engaged.

There is usually a group of switches (pistons below the great manual) that enable lower MIDI channels when engaged. More expensive organs have two switchable channels for each manual, such as MIDI GT A and MIDI GT B (great manual A and B channels). Only enable one of these when setting up the keyboard (maybe B for Bells).<br> | ||

The Millennium/Platinum carillon can respond to two MIDI channels simultaneously, and we refer to them as Primary and Secondary. When setting up a system with an organ, the Primary channel is typically the lower manual (Great) which is used for the melody bell voice and the Secondary channel is set to the upper manual (Swell) which is used for a harp voice. | The Millennium/Platinum carillon can respond to two MIDI channels simultaneously, and we refer to them as Primary and Secondary.

On the Millennium Carillon, note velocity affects not only the volume level of the note but also the brilliance of the note. Playing vigorously will be brighter and louder, playing gently will be duller and quieter. | On the Platinum/Millennium Carillon, note velocity affects not only the volume level of the note but also the brilliance of the note.

Organs do not typically have a touch sensitive keyboard. Instead we have to rely on the expression pedal (in the case of an electronic organ). On an Allen organ, the expression shoe controls the note velocity values affecting both volume and brilliance. | Organs do not typically have a touch sensitive keyboard.

Firmware versions prior to 0411 would accept volume levels of zero and mute the output. This is now ignored since we have run across a Solid State Logic midi interface (probably not installed and setup correctly by the organ technician) that sent a volume zero command every time the MIDI output was enabled. | Firmware versions prior to 0411 would accept volume levels of zero and mute the output.

== [[ | == Import MIDI file == | ||
=== Advanced eXperience models === | |||
Use [[Using_Chime.Center#Uploads|Chime.Center's MIDI Upload]] page to import MIDI files to your ringing system. | |||
MIDI type 1 files are compatible with the AX systems as long as there is only one track. | |||
=== Legacy 2000 models === | |||
You can import MIDI files from notation software to your carillon using the Management Suite's [[Recording_library_MS|MIDI File Import]] premium feature. | |||
Without the Recording Librarian option, a supported carillon can only store one MIDI file at a time in the recording buffer. | |||
=== Preparing MIDI files for upload === | |||
Only single track [http://en.wikipedia.org/wiki/Musical_Instrument_Digital_Interface#File_formats MIDI Format 0] files are compatible with Management Suite. | |||
If you selected a preset voice on your computer to play back the arrangement, delete that preset before saving the file for upload. | |||
It is important to transpose the music properly for the bell voice you will use to play it back. Automated chimes and carillons are always transposed to ring the largest bell on middle C, or C4 (Midi note 48) regardless of their true pitch. Millennium Cast Bronze carillon voices range from C3 to C8. Millennium Chime and harp selections use a split keyboard with the harp from C3 to Bb5 and the chime from B5 to C8. Notes above and below these ranges are prohibited. | |||
Tempo and time signature changes are supported. All other controls such as volume and patch changes must be removed from the file. | |||
Stacking lots of notes in fast changing chords may overload the playback engine of the carillon or bell controller resulting in a slight slowing of playback tempo. Quickly arppegiating dense chords will avoid this slowdown without a noticeable change of arrangement. Striking the larger bells before smaller bells is customary. Arrangements that are kind to the listener's ears will avoid striking more than two notes simultaneously. | |||
[ | A useful article, [https://www.rockefeller.uchicago.edu/2017/12/19/composing-for-carillon ''Composing for Carillon'' by Joey Brink], should be reviewed when arranging music for bells. | ||
