the Integrated Piston capture combination action

Thousands know the joys of an SSOS MultiSystem. It's flexible, fathomable and programmable to fit any organ. Luckily, CFM is the capture system specially made to match it. Using Multi-System wiring already in the organ, CFM connects instantly without interfaces, links, tears or rages.
Compact and hassle-free Instantly recognised by MultiSystem
40,100, 300 or 1,000 levels, or a Library system with virtually unlimited levels to accurate multiple organists. All fitted now or upgradeable later
One unit sets 1000+ stops and four crescendo settings
Combination memory can be shared by multiple consoles or split between two.

How CFM matches a MultiSystem

As CFM uses the stop inputs already connected to the organ's MultiSystem, the only things left to wire are on/off coil inputs and piston inputs. Fitted on the same wiring plane, they can be neatly tucked away. From then on, CFM is set up like any SSOS capture system. All aided by regular checks and tell-tale LEDs.

CFM Memory System

The fastest most accurate organ control system in the world

Our MultiSystem switching systems can be built with any number of inputs, outputs and stop controls. The system is configured in software which allows the for an extremely flexible structure and straightforward building blocks.

A location is built from a processor, a plane (to put the cards on) and a choice of positive or negative polarity, input or output cards. The system is controlled by software which is loaded into each processor.

The MultiSystem is built around high specification industrial processors that run a custom operating system designed for high speed real time processing. The total boot time is about 6 seconds and so the system is ready to run before the wind is up.

Communication between locations is by CAT5 100BaseT Ethernet cabling. Although the protocols running on the cable are fully compatible with an Ethernet system we only support a closed network that is solely for MultiSystem use, this is because we can only guarantee performance if we know the amount of traffic on the network. It is possible to use a 802.11 Wireless network but again we cannot guarantee it will be to our performance requirements due to an inability to control external interference.


Solid State pioneered the use of punch blocks in organ building, however we selected a high performance connector from a German manufacturer called Krone that has been in use in the European telecoms industry for 80 years and more recently was adopted for internet connections in large office buildings around the world. It has been used by us in organ building since 1991.


MultiSystem operates between 12 to 36-volt as standard. The system itself uses less than 1 Amp to operate, however care must be taken in providing adequate current to switch the organ loads.

Outputs -

Output modules provide 16 outputs per module. They are provided with Krone connectors to punch the wires directly to them avoiding an extra connector and hence increasing reliability. The module has built in suppression.

  • Negative Output - 0.75A maximum rated. Equivalent to 16 Ohms at 12V or 32 Ohms at 24V.
  • Heavy Duty Negative Output - 1.4A maximum rated. Equivalent to 9 Ohms at 12V or 18 Ohms at 24V.
  • Positive Output - 0.1A maximum rated. Equivalent to 120 Ohms at 12V or 240 Ohms at 24V.
  • Heavy Duty Positive Output - 1.4A maximum rated. Equiv to 9 Ohms at 12V or 18 Ohms at 24V.

Inputs -

    Positive Input - A high resistance input with built in surge protection and debouncing for dirty key contacts. The module loads the contact by less than 10mA and will accept inputs from 10 to 36V.

  • Negative Input - The same specification but an alternate polarity.
