osu! "Rhythm is just a click away"

   This is part 2 about osu!. I am going to show you how to create a beatmap as I promised last week. You can refer osu! as "plagiarism"; however, it's still worldwide popular. Why? Osu! adds huge customisation via skins/beatmaps/storyboarding, online rankings, multiplayer, all of which are the keys to success. The significant feature is making your own beatmaps, and it is the topic this week.

   Before beginning the topic, I want to make sure that you all know what is "BPM". 陳昶昇 have taught us last week. See http://b02203013.blogspot.tw/2013/10/introduction-elements-of-music2.html. Let's do one exercise.
   A famous anime song "only my railgun" is measured as 143 BPM, then (a) How long is the time between two adjacent beat? (b)  There are 56 bars in this song of TV size and four beats per bar. Determine the length of it.

If you know the definition of BPM, you can get the answer easily.
ANS:(a) 60/143=0.420 s
    (b) There are 56*4=224 beats in total, so the length is 224/143=1.57 min=1'34".

 Now let's start learning the most interesting part of osu!, making your own beatmaps! I'm not a good mapper, so I just show you some tutorial clips only for osu! standard. It may be quite boring.

This is the end of osu!. I will introduce other rhythm games next week.
