The sequencer allows the storage of
a completely independent set of general registration settings
that are instantly recalled using a NEXT and PREVIOUS piston.The
size of the organ will dictate the number of sequencer settings
that are available. Normally up to 1000 sequencer settings can
be stored, equivalent to an additional ten general pistons on
one hundred levels.
The sequence number therefore represents
the registration steps through a piece of music. In many cases
reflection will dictate that changes are necessary and may involve
the addition or removal of sequences. The INSERT and DELETE switches
have been provided for such occasions. The INSERT function allows
one insert to be made between two sequences and is indicated
by a suffix A to the display. The DELETE function allows a sequence
or a set of sequences to be deleted.
In addition to the next and previous
pistons a RESTORE piston is provided. It must be remembered that
the sequencer works alongside and in addition to the normal piston
system. A visual LED is provided to indicate when the sequencer
display has been over-ridden and is no longer valid. This could
occur when the registration has been changed by hand or by use
of pistons. The RESTORE piston is used in this situation to restore
the registration to that indicated on the sequencer display but
not advance to the next sequence. |
