Honestly the more I hear these presets demonstrated the more I want to cry. Why are so many of them not allowing the samples to breath? There seems to be a lot of focus on decimating or bit crushing the samples to the point of noisy industrial type sounds and there seems to be a lot of focus on the synth engine as well. I feel like the demos and presets really have done a disservice to showcasing what this thing can do. I understand in most cases presets are awful but these are just downright ugly sounding. Ugh, I wish DSI contacted me about doing some patches for the thing.
I think that's a pretty harsh assessment, which I don't even mean in a defensive sense due to having been involved in the process. I do get that you'd prefer to listen to some sample-only content that's only slightly processed at best, be it out of curiosity, be it due to personal preferences. And that is absolutely fine. But also consider that it's almost impossible to please everyone with presets. There are currently 3 goups of people: One would like to hear what you want, another one wants exactly the opposite (only oscillator-based sounds without any samples), yet another one wants only hardcore-mangled sounds because they think everything they've heard so far is not experimental or granular enough or too tame. Taking that into account, I'd say that the current presets provide a rather good compromise to hold these different interests together.
And there are also always mandatory rules for sound design, which pretty much write themselves based on an instrument's features: For potential customers all controllers like AT, mod wheel, and touch sliders obviously have to have an effect, most of the effects need to be showcased in some shape or form, particularly new ones if there are any (which of course doesn't mean pushing it to 11 all the time), the sequencer needs to play something if there is any, and the general philosophy behind the instrument has to be communicated, i.e. in this case that this is a synth
and a sample playback instrument with sample manipulation options. Those are just self-evident preconditions that need to be catered to for any existing synth out there before you even start to think about a particular sound. Presets are not only supposed to sound cool (strictly subjective of course), but also carry the function of showcasing an instrument and all or most of its possibilities. You should also consider that—as usual—it'll be up to you to eventually create the stuff you like with this instrument.
And on a personal note: There are at least 3 presets in my playlist that pretty much fit your desription above. One is a rather pure Rhodes sound with only additional effects that are dialed in via the touch sliders and mod wheel (phaser, delay, and tremolo), "Fashion Magazine" also only makes use of non-mangled samples, same as the tongue-in-cheek "Chill, Dude!", and even the last track uses mostly EMS-based synth samples, where only a sine wave takes over the role of a supporting sub oscillator. Whether those examples fit your personal style is another story, but there are quite a few sounds from everyone that only make sparse use of the oscillators, or use them in a rather supportive manner and not as the main tone generators. The problem may be that you cannot always hear that, or that you can only know this if you actually see how the according sounds have been made.
