Ian Alderman made a number of 20-note roll playing organs in the early 1990s.

With my assistance, he went on to develop the 26-note scale, by using the blank space on the edge of the 20-note roll to fill in the missing notes. The great advantage of this method was that 26-note organs could play the standard 20-note rolls without modification, as well as the enhanced 26-note rolls. This was significant, as a vast library of music was already available on 20-note rolls. With the same number of sharps, 26-note organs can play the same range of music as 31-note organs.

Ian made a number of 26-note organs, whilst I supplied the majority of new 26-note music at that time. We made efforts to popularise the new scale, but hardly any English organ builders were making roll-playing organs at that time, so there was little interest from this country.

However, with the passing of time, many organ builders are now recognising the benefits of adding those extra 6 notes to their organs, and other music supppliers on the Continent are also supplying 26-note music. As a result, the 26-note scale has now become very popular. The scale was given a big boost by John Smith, whose Universal DIY organ uses the 26-note scale.

Builders of 26-note organs include Peter Trueman, Paul McCarthy, Jaeger & Brommer, Stuber, and John Smith, but there may well be others in other countries.

Alderman & Davis no longer make organs, but they are still producing music rolls.
