They are mono but good sounding, and respect the resonance of the 54 bells, from B flat to F, on 4 octaves. The samples have been converted from mp3 to wave, and regularly disposed in space from left to right, using the pan adjustment in the soundfont with Vienna Soundfont.
In this belfry, there are no bells for the B and the C sharp of the first octave. To respect the original instrument, i did not add these missing notes. If you want them, and if you know how to make soundfont, you can interpolate them easily. The whole soundfont weighs 26,2 MB. If you want the Hauprtwerk version, please go to Soni Musicae / Hauptwerk.
The soundfont was created by Soni Musicae but the samples are free and come from Ghent (Belgium) city's clock and were made available by a non-profit organization. The original site is now dead (but is linked here and can be accessed via Internet Archive) so most of the uses here should be okay.
