4. Envelope is a shared control for the release with 2 retrigger modes. 

Organ section

-Octave mixer Organ have different octave feet that can be mixed: 8' 4' 2' 1' 
    Organ I -II / Tone 2 different kind of organs (First one is brighter)
   Organ I-II (later version)
   Tone I-II (early version)
- Ensemble _ Turns on/off the chorus effect. 
Organ Tab  * Only on early version *  a kind of mono mode, sound goes out from the dedicated out.
