Description

The next step in organ building: decentralized systems with tone hole masking and dynamic valve control. Program even complex action functions yourself via Excel spreadsheets.

After the proven W1, the next generation W2 is now available.

The windchest module brings the intelligence of organ control directly to the pallets. The compact, robust housing can be mounted directly on the windchest. All components are integrated: power distribution and fusing take place on the circuit board. Only the power supply (12-24V) and an Ethernet bus line need to be connected. Instead of numerous multi-stranded organ cables, only a few power lines and prefabricated data cables need to be connected when the instrument is assembled at the installation site.

The windchest module is designed to be used with ribbon cables and crimp connectors, which have been tried and tested in communication electronics for decades. The connection to the module is made via connectors that are pressed onto the cable without any stripping or soldering. Two wires are already assigned for each magnet.

New in the W2 version: In addition to the ribbon scable ystem, connections for single wires are now also provided for all outputs and bus lines. This allows you to connect some or all of the output banks with organ cables or other types of wires as needed without expensive adapters or cumbersome terminal blocks. The outputs of a bank are available on a 12-pin connector (negative-switching). On a 2-pole terminal are the two separately fused positive common lines for 6 magnets each.
Please note: The optional connectors are not included in the delivery. You can oder the connectors with Cage clamp terminals separately in packaging units of 3 pieces each. This allows you to decide for which parts of the windchest you want to use the single-wire cabling (e.g. for remote facade chests).

Because the module remains on the windchest, you can completely pre-wire the chest inside your workshop; there is no additional workload for disassembly prior to transport. A MIDI keyboard is all that is needed. Pairs of C and C-sharp chests are connected via a network cable so that a complete divisions can be pre-voiced on the chests.

The intelligent control makes the so-called tone holes disappear in an almost magical way. These holes are created when pipes on individual chests are played by different stops or by coupling different manuals. The intelligent windchest modules can mask tone holes using a patented process.

The Espressivo windchest module is the ideal complement to the Espressivo contact system for keyboards. Since its market launch in 2013, it has largely displaced conventional electronic contact devices that work with light barriers.

In addition, each time a key is pressed, the keyboard detects the speed at which the key was pressed. The W1 module can use this speed information (MIDI "velocity") to supply the valve solenoids with modulated currents at different speeds. This novel "dynamic valve control" enables subtle articulation effects in what is otherwise often perceived as soulless electric action.

Windchest modules can be used as an alternative to or together with the usual output modules of PLC controls. The functions of the central capture system (recording/playback, touchscreen control, etc.) are independent of the output hardware. Specific W1 functions, such as tone hole masking, are only available at the module Outputs.
