Adrian Goodwin,

Working in reverse here.... 

Maas-Rowe has been in business since 1922.  The son of the founder of the company, Paul Rowe currently president of the company is his golden years.  

The DCB1 which was Maas-Rowe's first generation of a digital controller in around 1983 has Westminster chimes, bell tolls for churches, colleges and universities.  For instance, Angelus, De Profundis, Change Ringing (Bell Peals), Swinging Bell etc.  There were two other generations of this product which followed.  The DCBII and DCBIII.  All three units use an external bell chime unit with chromatically tuned bell rods with the additional partials needed ground into them.

Here is the external Bell Unit which can connect to a DCBI, DCBII or DCBIII. The Bell unit contains 15 bell rods, and they are divided up into the Low C chord of 3-bells. The rest are divided up into groups of 2-bells.

The DCBI used 8-track cartridge tapes for the musical selections.  The DCBII (discontinued) and DCB3 use a 7 or 25 disc Compact Disk Mechanism for the musical selections.

Six years ago Maas-Rowe Developed a Digital Sequencer unit which contains up to 25 "Libraries" of musical selections. It also contains the 7 bell voices which Maas-Rowe patented played in "real time" from digital samples.

In addition Maas-Rowe has manufactured for several decades what is referred to as the Grand Symphonic Carillon.  It allows you to play from a keyboard console, and it also can contain their MPR1 and MPR2 unit which has musical selection storage and a sequencer.

A sample of The Grand Symphonic Carillon can be seen here:

Donald,

I'm interested to hear more about the Maas-Rowe controller. I presume something that plays a fixed peal on the chimes ?

I found another You-tube video where someone was describing a set of chimes, but it had a tube amplifier and a small manual keyboard. He didn't describe any sort of automatic player, and from the age of the system I would imagine it would have been semi-mechanical, like a player piano.


How does the controller you  are restoring operate ?
