Organ of the church of Romanswiller
It can be downloaded starting from the site of Joseph Basquin
http://www.jeuxdorgues.com/doku.php
It is an instrument with two manuals, pedals and 23 stops, needing 100 Mb of ram memories.
Perhaps you expected more memories , but the 188 Mb of pipes samples are compressed by MO when loading.

It is the free organ most complete  you can find on the Web, with divisionals, generals memories and an expressive pedal that we will learn how to actuate by Midi message since HA.

If you have really very little random access memory, do not charge the
"living room" organ, although having only 5 stops it requires as much
memory than the preceding organ. That is with the fact that each pipe was
sampled over one very long period of time (it is sampling the ideal).

Test HappyBirthday (9 stops) or mini Smecno (4 stops), these are the
smallest organ free that I found, but there is not a large difference with the
two others about the memorie place they need.
The organ Smecno Mini. 4beautiful stops
