I have this weird thing with synthesizers and manual modes. Currently encountering this with S6 but it’s the same with other synths and manual modes. No matter what kind of sweet patches I save, whenever I come back to the synth the patch never sounds as sweet as I recalled and then I toggle the Manual mode and I’m blown away.
This makes me wish that mod assigns would persist in manual mode. That there would be some kind of interface to make them “manual” settings. 
I’ve tried to min-max the init patch to a great electric piano, I’ve tried saving the manual patch and switching to that every time I come back, but it doesn’t sound as “wow” as it did.
I think when I’m using the synth some subconsious process of mine keeps the synth “alive”. Maybe I’m switching the faders and knobs and switches to something I want to hear without even realising, then when I come back it does not reflect the bliss it was anymore.
Any kindred spirits out there?
I’m definitely for WYSIWYG synths and I would encourage UDO do abandon the whole patch saving system for their next instrument. 
Just a clear UI that invites play with no abstractions…
