E-Player

   A MIDI music playing system -- I call E-Player -- which I build for pipe organs and player pianos.  It is basically an electronic version of paper rolls.  It has software that converts the MIDI files (single track) and sends them to an electronic circuit that turns the pallet valves on and off to the melody and timing of the music.  Music can also be put in, one note at a time, from sheet music.  This player system works through your computer and/or music can be loaded onto EPROMS and played as a stand-alone system.  Operating systems are DOS and Windows 98 or earlier.  It will not run on computers using Windows XP.  This E-Player system is ideal for a one or two rank organ, and will possibly work on as many as three ranks, depending on the current draw of the pallet valves (0.5 ampere max. each).  It has a maximum of 112outputs.  It is relatively inexpensive compared to a other MIDI player systems.  It includes the software, E-Player circuit board, a 5 VDC power supply and a 12 VDC power supply (or a power supply as high as 50 VDC), wiring schematic, wiring instructions, and some sample music to play on your organ or piano.  In addition to playing from your computer, small EPROM plug-in boards are available, that allow you to store the music and play it without the computer.  The programming of the EPROMs is not included, and would be your responsibility.  It is relatively easy to wire and install this E-Player system to any pipe organ, and it can be adapted to paper roll player pianos if solenoids are installed in the existing vacuum lines, or to any piano if electronic solenoids are installed under the keys.  Each system is set up by me to your particular organ or piano needs.  I am currently building these E-Player systems for a calliope manufacturer.  Anyone interested can contact me for more information.  I'd be happy to play my pipe organ for you, over the phone!
