Eltec’s ORGDRIVE-CP25 Proportional control system enables Organists
to control the opening of a pallet directly in relation to its corresponding
key.
Essentially, the system splits the movement of each key into 128 individual
levels using Hall sensors. In the organ, specially-designed magnets re-convert
these levels into 128 individual pallet movements
The main components of the system are as follows:
Proportional
Keys.
A Hall effect sensor connected to each key breaks down its travel into
128 values (levels) and converts these into an input for transmission.
The system’s accuracy and regularity is assured: any inaccuracies
in the keys themselves (like simple makers’ errors or temperature
changes) are quickly compensated for using the system’s set-up software.
Please note that proportional keyboards (described in the Accessories
page under “Static Keyboard with Hall Sensors”) can also be
used with a standard Orgdrive system: eliminating traditional key-contacts
provides an appreciable increase in all-round reliability.
Proportional magnets. These
are specially designed to open a soundboard pallet in a gradual and controlled
way, exactly in accordance with the key-movement data from the console.
To maintain their accuracy, proportional magnets will also “re-learn”
pallet positions automatically: this way, the natural “bedding-in”
and settling of pallets can be allowed for. A simple self-learning sequence
can be periodically and automatically sent to every magnet using a simple
command from the console.
Along with the unique functions described above, the ORGDRIVE-CP25 system
embodies the programmability, reliability, flexibility, and simplicity
of installation of the STANDARD ORGDRIVE system:
Programmability. In addition to notes, stops and combinations,
all console functions (such as full organ and crescendos) and other organ
functions (like swell shutter control) are all managed by the same system.
Every function can be activated in the organ itself via any Personal Computer
equipped with a standard serial RS232, using software provided and updated
free by Eltec.
This software enables organ builders and organists to configure the system
and adapt it precisely to their needs – from eight 61-note keyboards
(a total of 498 inputs) to a single manual with 58 keys and a 30-note
pedalboard.
Alternative programming. Organ builders can alternatively supply
us with complete organ specifications. Eltec’s personnel will then
configure the central processor and supply it pre-programmed and ready
to use.
Characteristics.
The ORGDRIVE-CP25 system enables 8 proportional keyboards to control a
combination of proportional and standard outputs via a single card.
A single ORGDRIVE exchange installed in the Console (known as the Master)
can control, via 6-way cables or a remote control, up to five ORGDRIVE
Systems (or Slaves) installed in as many separate organ bodies irrespective
of position.
Moreover, any ORGDRIVE system can be equipped with a comprehensive array
of
accessories ,
described in detail on this site.
For more information, the site contains brochures that can be downloaded;
Operation Manuals and other data are available directly from Eltec Automazioni
by e-Mail, Telephone, or Fax.
Main characteristics
and maximum limits of the ORGDRIVE system.
CONSOLE:
- Keyboards = 8 Keyboards - 61 Keys/Keyboard
- Stops = up to 250
- Full/Tutti/Reeds = 16 Inputs + 16 indicator outputs
- Fixed combinations = 4 Groups o max. 5 pistons with
indicators (6 Inputs / 5 Outputs/Group)
- Crescendo = 99 Levels of Pedal input - 32 Levels of
pedal position indicator output
- Cancels = 24 Inputs + 24 indicator outputs + General
Cancel
- Transposer = 8 Inputs (-4 to +3 semitones) + 8 indicator
outputs
- General Adjustables = 16 Pistons with indicators x
999 Levels – Level Freeze Option
- Departmental Adjustables = 8 Groups of 8 Pistons x
999 Levels or 16 independents levels
- Reversibles = 16 Inputs + 16 output indicators
- Auto Pedal = 1 Input + 1 output indicator
- Swell Control = 64 managed Inputs with contacts and/or
three sliders for individual pedals.
Levels:
32 Levels of output indicator position for each of the pedals installed
-
Radio Link =
1 Input + 1 output indication, 869 MHz
Important:
- All inputs can be programmed to be connected to momentary contacts (i.e.
key contacts) or switches, such as those on stop controls.
- The indicators can be omitted if not required.
ORGAN:
- Total Output Groups (Proportional + Standard) = 32
- Outputs for each Standard Group = 128
- Outputs for each Proportional Group = 128
- Stops = 250 Outputs with the option of just programming
the outputs of the actual registers
- Swell Controls = 64 Outputs.
