Temperaments in new GO can't work with any sample set.
First needed that the samples have inside them the relative pitch information and second one must add some (or many..) lines in the .organ file.
The basic line is : HarmonicNumber=
This line is added in the odf just before the samples per pipe description begins. This way will affect the whole rank.
This is easy for all kinda ranks except mixtures.
Here we need to add HarmonicNumber= to each wav file that has the mixture in question (the main, not the releases) and can be very tricky because almost every mixture is different (not that there are not some identical) and changes from oct to oct even half oct to half oct.
Here I describe how I'm doing this and have all GO temperaments working (provided that the samples have the pitch info written) :
HarmonicNumber=2 for 32' stop
HarmonicNumber=6 .... 12'
HarmonicNumber=8 ..... 8'
HarmonicNumber=24 ... 2' 2/3 or 3'
HarmonicNumber=40 ... 1' 3/5
HarmonicNumber=48 ....1' 1/2 or 1' 1/3
This is a basic way. Please correct any mistakes those of you doing it other way.
For Mixtures I can, for now, share two examples :
a Scherp IV which changes in half octave (F) and a simpler Cimbel II which is unchanged for the first 3 octaves.
HarmonicNumber= must be added JUST AFTER MAIN PIPE/WAV description (careful here)
Scherp IV :
Pipes 001 ~ 006 set HarmonicNumber=128
" 007 ~ 012 HarmonicNumber=96
" 013 ~ 018 HarmonicNumber=64
" 019 ~ 024 HarmonicNumber=48
" 025 ~ 030 HarmonicNumber=32
" 031 ~ 036 HarmonicNumber=24
" 037 ~ 049 HarmonicNumber=16
Cimbel II :
Pipes 001 ~ 036 set HarmonicNumber=48
" 037 ~ 041 HarmonicNumber=32
" 042 ~ 054 HarmonicNumber=24
Examining the way we did (odf) in Pitea set, which has many bright and complex mixtures, one can get many information on the matter.
Finally attached here is the odf Antonio (Larioant) shared some time back for the releases thread, in which I added the HarmonicNumber for every rank, so this shared odf/set can be used with all GO temperaments, especially for those who want an equal one, or a Couperin possibly? :-)
Have fun !
