John Robinson Posted May 11, 2006 Share Posted May 11, 2006 As a non-playing member of this forum (my interests are mainly design and history), I would be grateful if anyone with practical experience could advise me of the comparative usefulness of different types of piston. As I understand it, there are basically three methods of rapidly changing combinations of registers: divisional pistons general pistons sequencers I assume that sequencers have great value when preparing for a recital, where one can step through an entire programme of music using only one piston, but what are the merits of divisional pistons as opposed to generals? The consoles of most English 'cathedral-sized' instruments always seem to include divisional pistons whereas the Germans appear often to avoid them, many consoles having general thumb pistons beneath the lowest manual only, presumably to allow the manuals to be placed closer together. Can anyone explain this difference in approach to accessing combinations? What are your personal preferences? With the potential of programming thousands of general combinations (using modern digital systems), are divisional pistons redundant? On a similar theme, what are your opinions of thumb pistons duplicating the stop controls for individual couplers? John Link to comment Share on other sites More sharing options...
