That means there's no rhythm, so that moment is unmappable. Consider using a spinner, a break, or just a pause with the object placement.
Stating a song has a steady 1/2 rhythm is a bold statement to make. Some songs divide into thirds, others don't divide at all. Stating that a song has a steady 1/1 rhythm is a basic concept of music theory. If your song doesn't have a 1/1 rhythm to it, but only a 2/1 rhythm (which corresponds to tick 0.5) then your BPM is double what it should be. Divide your BPM by two, double your slider speed, and enjoy your "tick 0.5" that way.I'm not sure exactly what songs you're considering, but there is a whole gray area in between having a lot of emphasis on a beat and having nothing there. Having no emphasis on a beat doesn't mean there's nothing there, there might be a slow vocal there, a sound coming from 1/1 or 1/2 before with no added emphasis, just a really slow, weak sound, or many other things. Tick rate 1 is too busy for those, but those parts would be mappable. Plus, having no emphasis on a beat doesn't mean that the rest of the song doesn't follow a 1/1, it means that one part in the song doesn't, so the faster BPM is still the right BPM.
Also, for easier diffs, as NatsumeRin said, tick rate 1 would sound too busy even if the song follows a 1/1.
That's basically what I said, only I'm more open to the possibility of patterns which aren't necessarily readable given the music, but still make sense in retrospect. These situations depend on tick reading or memorization, but shouldn't necessarily be outright banned.It's not good practice IMO to force ticks just to "ensure" that everything is readable. Just because some maps would need ticks for speed changes doesn't mean that they should be forced on all the other maps, especially when it doesn't fit
Most if not all songs have exceptions. What matters is that the 1/2 rhythm is stable.if tick 2 clashes, it sounds really bad because it's too busy and has ticks that fit to nothing. If tick 1 is used with a 3/2 slider and the tick it puts is out of place, then this is one case I mentioned where tick rate 0.5 sounds way better. If tick rate 1 puts an out of place tick, tick rate 2 will sound even worse because the whole rhythm it creates doesn't fit. >.<
Edit: I think you misunderstood. Allow me to rephrase that one:
If tick 2 clashes, so you opt for tick 1, you may experience "syncoticks" on sliders that begin on 1/2s. This is usually a sign that tick 2 is correct, but if it isn't, try to place objects more carefully. Tick 0.5 has syncoticks too! It even has them with sliders beginning on 1/1 offbeats, which almost always sounds awful. See my screenshot below.
If you're using such a long slider (like in that screenshot) that doesn't call for any ticks, then there's nothing to do besides dealing with the tick, but at least it sounds better than if you used tick rate 1 or higher...
What I mean is if there's an out of place tick even with tick rate 1, then tick rate 2 will sound even worse
Please link me that map and I will look into a better solution.sorry, I misunderstood what you said, so it doesn't fit your example. However, my map had a slider that started on a 1/4 and lasted 5/4 so tick rate 1 put an out of place tick (though looking back on that, I think a 3/4 slider and another beat might have been better)
