MIDI Scene Control



  • Hi everybody!

    Im not a very experienced Isadora user yet, so maybe this is a stupid question.. but still Im having a hard time solving it even though I read the manual and searched this forum.

    My goal is simple. Trigging Isadora from a lighting console by sending midi notes. I want to send a separate midnote for each scene since Im working with a theatre production that has a lot of synchronization between light, sound and video. "MIDI Scene Control" actually does pretty much what I want, the only problem is that the scenes dont fade between each other. For example the first scene is trigged by Midinote Channel 1, Velocity 1. The second scene is trigged by Midinote Channel 1, Velocity 2, and so on. What I want to do is of course specify the fading time between this scenes.

    Can anyone point me in the right direction? Do I need to use a lot of midi actors instead?

    Best Regards,

    Einar



  • I think I posted a user actor a while ago that does exactly what you are wanting.  I don't have time to search or repost it right now, but you could search this or the old forum.

    What lighting board are you using?  They all send MIDI data a little differently.

  • Scene jump has fader built in. And I would use Note On Watcher and send notes(pitch) not velosity. 753b5a-scene-fade.izz



  • Thank you for your fast replies! Much appreciated! It took me some time to answer, because I needed to get back at work first..

    CraigAlfredson: Tried searching the forum for your actor, haven`t found it yet. Running a GrandMA 2 and sending MIDI notes. Here are the details in regards to MidiNotes from the GrandMA 2 manual:

    MidiNote is a function used to transmit MIDI Note-On and Note-Off messages. Syntax: 

    MidiNote [note] MidiNote [midichannel].[note]MidiNote [note] [velocity]MidiNote [midichannel].[note] [velocity]MidiNote [note] OffMidiNote [midichannel].[note] OffMidiNote [note] [velocity] OffMidiNote [midichannel].[note] [velocity] Off

    vanakaru: Thanks for the Isadora example! You have to correct me if Im wrong or have misunderstood, but I dont think this solves my challenge? For example what if I`m in scene number 89, and want to jump directly to scene 14 by midi command? Apparently Isadora is only listening to the Note On Watcher Actors that are in the current scene. Is there any way, without having to add 100 "Note On Watchers" and "Jump Actors" in all the scenes, to make Isadora listen to midi all the time? Thats why "MIDI Scene Control" seemed perfect, except that its not fading between cues.

  • Dear Einar

    You don't have to have 100 Note On Watchers. Take a look at the attached patch -- it uses the concept of the "Secondary Scene" as explained in [this tutorial](http://www.youtube.com/troikatronix#p/u/8/wSaX-rKmWgc). 
    Press the space bar to activate the system.
    Send a Note On message with a pitch of 0 and the patch will jump to "Scene 1", A pitch of 1 will jump to "Scene 2", etc. You can adjust the 'value 2' input of the Calculator actor to get different offsets from the MIDI note to the Scene it will jump to.
    You could, potentially, also use the velocity to control the fade time.
    Hopefully this will lead you in the right direction.
    Best Wishes,
    Mark

  • Thanks!

    I tried your file Mark! It all makes more sense now. I`m slowly getting into the concepts of Isadora and are starting to see its power! I managed to control the fades with velocity, so thats cool.

    I still have some problem understanding the trigging of the fades though.. When using your file Mark, I successfully use the midi pitch note to jump to the scene I want, and by using velocity I can set the value for fading. But if I don`t want to use the velocity for fading, and want to use a jump++ actor, how can I set different fade times for all the cues?

    Again, thank you so much for helping me through this newbie questions!

    Einar



  • Dear Einar,

    RE this question:
    _"But if I don`t want to use the velocity for fading, and want to use a jump++ actor, how can I set different fade times for all the cues?"_
    Well, that's a much more difficult problem. You'll probably have to resort to using the Data Array actor -- not the easiest one to use I'm afraid. But if you do, you can save your fade times in an Excel spreadsheet and then import them. I'll let you start researching the Data Array actor -- check out the manual. Let's see how far you can get.
    Best Wishes,
    Mark


  • Thanks for your fast response Mark! For the moment Ill stick to velocity then, I when I get time Ill explore the Data Array actor.

    Thank you Mark for a great program and you all for an excellent community/support!

    Regards,

    Einar

    Its very low quality I am afraid... I did it a while ago but it might help get you started...
