 organ.

 Features:
    - 61 keys
    - Two main voice sections
    - Switchable bass section
    - Generator + matrix mixer => no polyphony restrictions
    - A realism control to add flaws found in the real organ
 .
 Flaws:
    - Takes quite a bit of CPU power
    - No touch vibrato

 The emulation is written in Faust and uses Jack for audio and MIDI.
