I`d like to subscribe to your mailing list. It was recommended to me by
Mr.Essl (essl@ping.at).

We are an austrian company specialized in building computer systems and
control-circuits.

We have now finished the developing and can offer a control-system for
pipe-organs using MIDI-STANDARD for all transmissions necessary (key, stop
and coupler action) between the console/consoles and the organ itself. An
electronical setter device for storing 5000 general combinations using PCMCIA
SRAM CARD for external memory is included in the system.

The advantage of this system is the possibility to use normal midi-devices
(keyboards, pc, mac, midi-mixer ...) for recording, playback, archiving,
editing, staff-printing, playing via telephone-line and so on.
The organ of the WIENER KONZERTHAUS will also be expanded with this system
in the near future.

Our WWW-Page is under construction and will be available soon.  For the
moment I can give you the following short description:

The modular designed system consists of four logical parts and works in the
following way:

1. Console Scanner Unit

This unit is wired to each operating element (keys, pedals, stop tabs, toe
pistons, coupler keys and so on), monitoring all actions taking place on the
console and converting them into MIDI Commands in real time. These commands
are merged by a MIDI Mixer and transmitted via MIDI OUT to the other parts
of the system and/or other MIDI devices like a PC or MAC  with sequencer
program for recording/ playback staff printing and so on. Due to the modular
design
of this unit there is no real limit to the amount of manuals and operating
elements.

2. Key Action Unit

This unit has MIDI IN/MIDI THRU and analyzes the MIDI Data converting the
appropriate Note on/Note off commands into switch commands for relay turning
on/off the voltage to the wired solenoids, depending on the assigned MIDI
channel and concluding from other MIDI Controller commands. Coupler  action
(including sub and super) is also solved by this unit if activated.
The unit is built to control one row of solenoids (up to 70) and can be
daisy chained depending on the needs. There is no limit in the amount of Key
Action Units within a system.

3. Stop Action Unit

This unit controls the solenoids of the stop valves or slider action motors
depending on the MIDI Controller commands  released by the stop tabs or
other MIDI devices.

4. Electronical Setter Unit

Electronical Setter for store/recall 4000 general combinations in internal
memory and 1000 general combinations in external memory using PCMCIA SRAM
CARD. This unit controls the stop tabs or draw knobs and also has MIDI
IN/MIDI OUT for controlling by a sequencer program or other MIDI devices.

Should you have additional questions about the system, I will be pleased to
answer them.

Kind regards,

Josef Grosssteiner
