Espressivo Manual

Detailed instructions for the installation of Espressivo keyboard sensors and configuration of the console system.

The master module is the central control unit of the Espressivo system. It supplies power to the sensor modules, processes the data and generates the midi signals to control an electric action or other tone generators. The manuals are connected to the six connections of the manual buses on the master module via Ethernet cables.

The current version 3 of the module offers even more possibilities:
In addition to the classic MIDI jack for keyboard data output, the unit has an additional pair of MIDI input and output. Via the additional output, suitable organ controller systems can output their own data, especially stop information for a full MIDI output at the console. For a MIDI input at the console, the master module now also provides an input jack. The data received here is forwarded to the organ control system. This allows the organ control system to provide full remote control of the organ from external MIDI-devices.

It is best to place the master module close to the manuals in the console. All bus sockets are identical, no special assignment of manuals to the jacks is necessary. The cable length between master and manuals should not exceed 2m. Only use high-quality, highly flexible cables. These are available here as accessories or in the Espressivo configurator.

The master module is powered via the plug-in terminal (12-24V). Please use a separate power supply for the Espressivo system (see accessories).

The key action control signals are output via the standard midi interface (DIN socket). In addition, the data is sent in "ipMIDI" format via the Ethernet interface. This interface operates about 300 times faster than the MIDI standard. Various manufacturers of capture systems, such as Eisenschmid, Heuss, Sinua and SSOS already use this standard. Drivers for Macintosh and Windows PCs are also available, allowing direct integration of MIDI software.

The Espressivo system can be set up and adjusted conveniently with the accompanying free Windows software. Use this software to set up the manuals, calibrate key travel, adjust contact pre-travel and modify the switch point spread.

The button battery on the master module is used to power the built-in real-time clock. The battery should last considerably longer than 5 years. An empty battery does not affect the system's function, as the clock is only relevant for the logfile functions.
