在本教学中，用户将学习到如何从MIDI文件中提取数据，并且将它用于钢琴动画与粒子动画。跟以往一样，我们将使用CMIVFX一贯的风格，使用循环，Hscript还有python编程来讲解一些高级的程序化建模技术。对于粒子制作部分，我们将使用VEX，不但用于制作弹道轨迹，也用于制作碰撞。通过学习本教学，你将会在你的digital assets中增加一些可以反复使用的东西。

cmiVFX has released the latest treat for its SideFX Houdini training product line titled "Houdini Audio Driven Animation". Modern technology gives us many opportunities to add a new sense to the common things. We can listen to the sounds of the universe, we can view the deepest ocean or we can visualize musical composition. In this video we'll do the latter. Using the time tested and industry proven Houdini procedural approach and its unique set of tools in CHOP, SOP and POP contexts, our piano will play in unusual way. In this unique training video, the user will learn techniques on how to extract data from MIDI files and how to use that data for piano animation and particle kinematics. As usual, we through back a nod to the well known cmiVFX style for making videos and break loose on some killer procedural modeling techniques using loops, Hscript and python scripting. For particles we'll use VEX, both for building ballistic trajectories and creating collisions. 燱hen your done watching this video, you will be left with a Houdini digital asset that can be reused again and again in your procedural pipeline.
