I like it because I always like playing songs quicker (especially if they have streaming!) but 1.5x is always too fast for me. A definable rate between 1-1.5x to gradually get better at higher bpm works perfect for me.
I absolutely support this feature request. As someone with prior experience with Stepmania, having more precise options for song speed rate really enhances the play experience. It creates a great environment for individual song practicing and tracking your improvement. It would also be very awesome to see which top players can pass the hardest songs with the highest speeds. It's not unrealistic to implement this either. Please consider it.
Starless support here; having a scalable song rate that also has an influence on the score multiplier for those who play modes where you get a score boost from DT/NC would be awesome, and would likely showcase those who have more speed than required for just DT/NC...
... on the flip-side, it would need to be balanced so that people can't just rely specifically on DT anymore than they did before a change like this happened.
Was thinking about this idea for some time as well, just never posted anything about it. For instance there could be a slider for dt and ht with values ranging from [1.5, 1.75, 2.0] for dt and [0.5, 0.75, 0.9] for ht and next to the mod symbol could also say the speed.
This could also be done with other mods as well for instance hr and easy which determines how small or large the beats are or something like that.
This could also add more variability in the scores without adding new mods, although there might be too much variety that it gets confusing when looking at the scores.
I don't know how to support this except for a reply;
I'd love to see that aswell with the pitch for nightcore... so that you have two sliders, wich determine speed and pitch. That's because from some songs I know a nightcore version and I think the normal is too slow, but double time is too fast and nightcore puts the pitch too high
