Lighted Thumb Piston); Non-Lighted Thumb Piston) - Johannus Monarke User Manual

Non-lighted thumb pistons
Non-lighted thumb pistons comes in two types:
! Thumb pistons that stay on (in) or out. The position of these thumb pistons indicates
whether they are switched on or off. (e.g. RO, WM and MT).
! Thumb pistons that spring back to the central position. These are usually the fixed
(preset) and free (capture) combination thumb pistons. When these thumb pistons are
used, the stops indicates which stops have been switched on or off by the fixed or free
combination thumb piston.
Now follows (in alphabetical order) a description of the thumb pistons that may occur on
your instrument. Further on in this manual the function of a thumb piston may, where
necessary, be dealt with more extensively.

0 (lighted thumb piston)

The 0-piston has a double function. You may have selected a fixed (preset) combination
or manually switched on a stop, but this is not what you meant. Pressing the 0-piston briefly
will undo the latter change.
Example
You are playing with the registration FLUTE 8', FLUTE 4' and FLUTE 2'. After some time
you add PRINCIPAL 8' and PRINCIPAL 4'. Obviously it takes some time (perhaps a very
short time) to switch on PRINCIPAL 8' and PRINCIPAL 4'.
Pressing the 0-piston briefly, will cause PRINCIPAL 4' to be switched off (undo latter
change). So PRINCIPAL 8' is not switched off as well (from the organist's point of view this
would namely be part of the preceding registration). The instrument considers, as it were,
the registration FLUTE 8', FLUTE 4', FLUTE 2', PRINCIPAL 8' the preceding choice,
whereas the organist sees the registration FLUTE 8', FLUTE 4', FLUTE 2' as the previous
choice.
Pressing the 0-piston longer causes - with a few exceptions - all the activated stops to be
switched off in one go. Exceptions are the couplers and the tremulants if the FA-piston is
pressed, and the stops Chorus, Intonation 2 and the MIDI-stops.
N.B. On instruments with wooden drawstops (Monarke models "Van Rhijn", "Gothique",
"Positief" and "Van Eyck") the 0-piston has the same function as the HR-piston. The
description of the HR-piston can be found further on in this chapter.

0 (non-lighted thumb piston)

By pressing the 0-piston on an instrument with non-lighted thumb pistons, you switch over
from a free (capture) combination to a fixed (preset) combination or hand registration,
depending on whether a fixed combination piston has been pressed or the HR-piston.
1 – 8
Pistons with which a personal registration is stored into the capture memory by giving them
a number (from 1 to 8 inclusive) within a memory group. These pistons are needed again
to recall the registrations stored into the capture memory.
An instrument may have one or several groups of pistons from 1 to 8 inclusive. If an
instrument has several groups of pistons from 1 to 8 inclusive you have free (capture)
combinations at your disposal which may be programmed for the entire instrument
(generals), but also for each division separately (separates).
