Thanks Graham
I have also started to make a five rank cornet, but not completed because it takes time, but it sounds fine.
to make the cornet, you have to create an special virtual organ with the five ranks and edit each rank volume until you get a correct cornet sound in which harmonics aare well balanced.
Then i create a piece of music with whole notes or half whole, in a chromatic scale from C-36 and separated by rest of the same lenght. I play it and record with myorgan at slow tempo. Then I split the file into 61 samples and make the loops. As you can see , a long task, but you can mak cymbale, mixtures, vvoix celeste, plenum ....
