Phrases are great and extremely powerful and everyone should be using them 
@eretsua if you like 12lpb, more power to you, BUTā¦ there is a great little tool called āplace selected notes evenlyā that you can set up with hotkeys to create tuplets of whatever variety you want (triplets, quintuplets, etc.) quickly and easily within any n-LPB based pattern. I used to use 24 lpb all the time, but have since switched to 16 LPB (for most projects) since getting this great little tool, and I use triplets and other tuplets all the time
New tool (3.1): Place selected notes evenly
I wanted to add also, that you could do a similar effect (to the OP) on the track (or track group) level using a one-shot LFO controlling filter cutoff, then using the LFO reset button to trigger note events. By automating the filter inertia, you could emulate the attack-smoothing. One advantage of doing it this way (instead of on the instrument level) is that you can use longer samples with complex evolving sounds changing in a rhythmic way over time. If you set up the LFO>filter on a group, you could even have multiple layers of differently effected sounds contributing to the overall rhythmic effect. Iāll post an example

In the above example Iām not trying to strictly emulate the OP example in terms of notes or rhythm or anything, just illustrating the effect on the track level. Iāve used chords from a PadSynth patch that are running through a modulated comb filter before reaching the LFO-controlled filter on the track level. This can easily allow for a more complex sound, if desired. Again, if you put the LFO controlled filter on a group track, you could have really interesting changing rhythmic stabs composed of several underlying timbres with all kinds of control possibilities
