I had checked the Fantom X manual and the 78 FXs in the JV-1080 plugin indeed seem to be identical to those in the JV-1080 plugin.fmr wrote:why we first got the D-50 that was originally released for V-Synth, and now the JV-1080 that was basically what was inside Roland Fantom, AFAIK. .
The samples in the JV-1080 plugin are similar to those in XV-3080, XV-5080 and the INT waveform bank in Integra-7. The Fantom X seems to have different sample content (and overall more samples) while a bunch of the included sample might be from the old synths.
You can check the waveforms of Fantom X here:
