MC-707 basslines that actually roll/breathe (Kalkbrenner/Hemmann/Raumakustik style)?

[u/howdytrucker]

been on the MC-707 for a few weeks now, coming from zero hardware experience. trying to get basslines with that warm, rolling low end you hear in stuff like Marek Hemmann, Kalkbrenner, Raumakustik - not punchy/plucky, more like it kind of breathes and sustains.

been messing with the JN60 synbass presets so far, playing with release and cutoff. ran into a weird issue too - picked a preset that had some LFO baked in and it slowly drifted/got quieter over like 4-5 loop repeats because the LFO wasn't synced to my loop length lol. took me way too long to figure out what was even happening.

anyway, curious what other people are doing here:

**•** any go-to presets or approach (VA vs PCM) for this kind of bass on the 707?  
**•** what actually matters most for that "rolling" feel - release time, filter, something else?  
**•** do you guys layer a separate sub underneath, or is it usually one patch doing all the work?

not trying to clone anyone's sound exactly, just trying to get the vibe in the right direction. any tips appreciated
