I personally find bass patches to be the most tricky to get right in general.
havent tried designing neuro things on DN but from my experience it seems possible.
judging from the examples youve given im gonna say that its going to be challenge to program all the worbly transitions because DN lacks parameter slides (only p-locks, which are stepped). So if you want to design tracks inside the machine without bouncing sounds into a daw, be prepared to create multiple patches of the same sound that have different LFO settings, ect. (one main sound and 1 or 2 worbly variations of it)
yes midi loopback is possible, also: https://www.elektronauts.com/t/digitone-tips-and-tricks/
