My Eminent 310u is sampled with Cubase 8.5 at 96 kHz and 24 bit stereo. With Strings Deluxe and basses I have sampled every note. With all the others I have sampled every 3 tone. This means that they are only drawn a half-tone to each side. There have been a few times I have had to re-record them, because I have not been satisfied.
The samples are edited and looped in Wavelab. I have tried to maintain the difference in dB’s in toners relative to each other. I think it helps to preserve the organ’s personality.
I also made setups for Cubase and Studio One Pro V3 to (try) get the famous Jarre sound.
But it is best is to use a Small Tone phaser to get the right sound.
The vst plugin that comes closest to the Small Stone phaser is Bigrock from Artsacoustic
