@RawTicks In the scenario of 37 steps it would not matter as it is not a equally divisible number, so 2 pages of 16 and 1 page of 5 would be ok. But for the most part when working with equally divisible numbers you would more often than not want pages to be of equal length, for example a 60 (4x15) step pattern is much more logically represented by 4 pages of 15, rather than 3 pages of 16 and 1 page of 12.
Elektron sequencers actually fare better here because you can just use 1 page and chaining to workaround it (albeit very wasteful of pattern memory) The Squarp does not have the luxury of many patterns due to the way it is structured, because you only have 1 pattern with 64 mute states (over simplification, but essentially true)
So I guess I feel that the Squarp strengths lie in its suite of data modification fx and composing, for live sets I'd find it very limiting if wanting to have no stopping between sections/songs.
Having said these comments I do feel though that the Squarp has enough for now to keep it interesting and useful to me, certainly the Squarp team seem committed to improving it through regular and substantial updates, and they also actively seem to be interested in user feedback for suggestions too.
