There's lots of ways to get punchier sounds, and also make the phasing detune thing mentioned not be an issue.
One thing is to try and set certain osc initial phases differently through the matrix.
Experimenting of course. The manual has this on it, but I found it does (for certain sounds) get rid of the phase issue that the poster above mentioned.
Osc Init Phase
This parameter sets the absolute starting phase of the oscillator whenever a note is triggered. As a conse- quence, it will no longer be in free-run mode. Set to zero, the specified oscillators starts at zero phase. An amount of +50 corresponds to a +180 degree phase shift, an amount of +100 to +360 degrees, etc. While the human hearing is largely insensitive to the starting phase of a single oscillator, the relative phase difference between both oscillators can matter in some cases, for example when both oscillators share the exact same frequency.
Another thing is, if you're going to use stacks/layers, then make the settings different for those stacks. If you just make 3 stacks and they're all 3 the same osc1 settings. Then of course you're gonna get that kind of phase issue. You'll need to set some with less detune, and change the "fine" settings in each osc differently, then try the osc init phase as suggested above. Not only different detune for each stack, but also the "Spread" (sprd) knob. Adjusting them will also help bring sound more to the front.
I rarely use the reset to get punch. I use other ways. The mseg's by making a downward fast sloping shape, then apply it through the matrix to some different targets. One would be the tune setting called (semi) and experiment. That's actually a much used technique in all other synths anyway. You can also try applying that to the cutoff filter, or even resonance to get good solid attack without that osc reset thing.
All I can say is after continual use for some days now. I'm blown away by Dune2. It really does reward extra effort.
