Welcome to Varomix Trix, in this series I'll show you tricks that I've learned along the way in my career, some are really simple but I think all of them will be useful.

In this lesson we'll learn how to use audio to drive any parameter in Houdini, this is using the amazing CHOPs context a context that is so amazing that will open a lot of doors for you.

    you left me stunned : )
    I can not believe that Houdini works with music.
    I asked for a few days ago if it could be possible, and opportunely you appear now with the answer : )

    this is my heavy music like you : )
    this is my new demo synth mostly, and it's the kind of symphonic music that I want to continue composing from now on,
    "Houdini" is almost one perfect site I think : )
    that's why I can not believe what you're teaching here !!!
    thanks again..

      Cool man, I bet you can have Houdini generate some of that it can output MIDI actually :)

    I have a problem,
    you here show the variety of ways in which you can create images that visualize the music,
    but my problem is that I do not know how to export in Mplay later with music ?

    I have a finished work, and I followed you steps in my end work, for add music, and it appear below in the time bar, and is ok!
    but when I exporting it does not do it with music.
    can you help me to export way ?

    • varomix 5 years, 3 months ago  | 

      you need to load the audio in mplay again or export the image sequence and compose them externally in premiere, after effects or something like that
