Re: Pitch Tuning in jOrgan

jbeach2646
The following Message works to vary the pitch of referenced stops in a disposition.  This variation is ascending from the recorded pitch of the wave file of the instrument used in the  preset of the soundbank.
 
Engaging    set 224, set 0, set value | mult 25 | add 51
 
 
Would it be possible, using jOrgan’s MPL and the slider elements in the packaged skins of jOrgan, to construct a pitch variation which can vary “minus six semitones” and “plus six semitones”
from the median of the recorded pitch of the wave file of the instrument?  Actually, the breadth of 6 semitones is not necessary, (simply an arbitrary), as the desired goal is to allow for
adjustable tuning, plus or minus, to match other instruments, piano or ensemble, orchestral instruments,  which the organ disposition might be required to accompany.
 
The slider elements of the classic skin in jOrgan have 10 green lights, starting left to right, effectuating increases in a given parameter value.   Seemingly, what would be needed is a slider with
11 green lights, the center light (6) of which would be the “default” tuning (the recorded pitch of the wave file of the instrument as in the Preset of the soundbank).  To the left of light 6, all values would decrease progressively, and to the right or light 6, all values would increase progressively. 
 
 
Has anyone tried, or successfully achieved such a “minus-0-plus” tuning capability in a disposition?   If so, could you, please, indicate the name of the disposition, in order that I might inspect
the element construction and messages of the MPL?     Specifically, what variations in the Message would be used to effectuate such a capability?
 
Thanks in advance for input on this.
