OSC remote control from Lightjams

[a6345634]

Trying to control ELM from Lightjams.

Simple sine wave for the outgoing OSC in LJ.

The OSC activity light is lit in ELM, but I was expecting to see the Intensity go up and down on the Live window, but nothing changes. I have one stage in ELM, and I then went to the Live Screen, and clicked on one effect.

What else do I need to do?

Cheers.

LJ OSC monitor as follows

Hi,

You should use Art-Net or sACN to remotely control ELM from Lightjams. Here's how: https://groups.google.com/d/msg/lightjams/_U8eHpfP3Fk/tFlXEfQuBQAJ. From OSC, you need to add the addresses ELM expect in the additional Lightjams' OSC out.

[a6345634]

Hi Mathieu, I thought I'd done that in the OSC output. I'll try Artnet.

I like the way ELM works in audio reactive mode, BUT I'd like to be able to set the "Mix Colours" on the Live tab remotely. This means I could use the same colours in ELM as from Lightjams.

Could there be a way to add remove and set mix colours (I would like to be able to add/remove/change 3 Mix colours) remotely?

Cheers.

 >> BUT I'd like to be able to set the "Mix Colours" on the Live tab remotely. 

There's a way to do that. Remove all colors from the mix colors and only leave the white. Duplicate your stage and set its merge mode to multiply. Remotely set the color filter of this stage via Lightjams.

[a6345634]

ok I'll try that. Can I do it with 3 duplicates, so I can set 3 base colours and have ELM switch between them, as if I'd selected those 3 colours as mix colours?

Does duplicating the stage have licensing implications? I notice it doubled the number of "LEDs mapped" under "settings"

[Mathieu Lightjams]

>> Can I do it with 3 duplicates, so I can set 3 base colours

No. You control the color filter from Lightjams. So it's up to you to change it when there's a music beat or something.

>> Does duplicating the stage have licensing implications?

No. The license is based on the number of DMX universes.

[a6345634]

In Lightjams I pick a base colour and also whether I want to use split-complementary or perhaps analagous schemes. That gives me another 2 colours. I then use only these 3 colours on my PAR LEDs in Lightjams. I don't use any other colours for that part of the song.

With ELM controlling the tubes, I still want to use only those 3 colours as "mix colours", until the next song where I'll have a different base colour in Lightjams.

With ELM in audio reactive mode, sometimes the colour changes on each beat, sometimes the colour stays the same for 8 beats then changes. Sometimes it changes fast, sometimes it fades into the next colour. I like this variation. If I set just a single colour in ELM remotely from the Lightjams base colour, then I won't get this variation in ELM, I'll just get the base colour on my tubes.

Does that make sense?

Licensing:- Is it universes or channels? Eg. If I use < 512 channels in each universe can I use more than 16 universes?

[Mathieu Lightjams]

>>  I like this variation. If I set just a single colour in ELM remotely from the Lightjams base colour, then I won't get this variation in ELM,

You can change it whenever you want in Lightjams - each X beat, based on the music speed, etc. There's no way to remotely specify a set of colors for the audio reactive mix. You either set it manually or you override it like I've shown previously.

>> Licensing:- Is it universes or channels?

Universes. License universes count adds up. So if you get another 16U license, you'll be able to use 32 universes.

Do you have a formula I could use in Lightjams that would roughly replicate the colour choice behaviour in ELM, assuming 3 mix colours? I have the same audio channel available in Lightjams. I could then use Lightjams to set the ELM colour, but still have the variations that I like from ELM.

[a6345634]

OSC send from Lightjams to ELM is working fine now.

[a6345634]

I think I'd need to control all the LIVE parameters from LJ, as I don't think I can just remotely control colour choice while the rest is audio reactive?

So is it possible to build a set of formulas in LJ to output ARTNET or OSC to ELM to control Intensity, RGB, Media, Speed, TransitionFX, duratio, mix, position A+B media and speed based on an audio channel in.

[Mathieu Lightjams]

Yes it's possible. Look at the Lightjams forum post in the previous replies. It shows one way to do it.

[a6345634]

That's great, thanks Mathieu.

I just tried the Lightjams project. Is the fixture mapping correct? The Intensity in ELM is stuck at 0.

[Mathieu Lightjams]

Seems to be ok. Follow the steps in the post (configure sACN, select the percent mode, put music on, etc.). It's just a sample project. So it's meant to be edited to suit your needs. If the intensity is at 0%, try changing it in Lightjams.

[a6345634]

Ok I got the remote control working - thanks. I've compared the built in ELM audio reactive mode with the remote control from Lightjams.

Would you be able to help get the Lightjams remote control to more closely replicate what ELM does when in audio reactive mode please?

Differences I can see:-

1. In ELM Audio Reactive mode, the Intensity slider pulses up sharply and down slowly according to the music. Under Lightjams control, the ELM Intensity is set to 100%

2. In ELM Audio Reactive mode, the Speed is fairly smooth (around 0.3 with the drum beat I am sending). Under Lightjams control the speed moves around much quicker, and is 3, not 0.3.

3. In ELM Audio Reactive mode, the colour sometimes switches quickly on each beat, sometimes on every 2 beats, and othertimes it will stay the same colour for 8 to 16 beats then slowly fade to another colour. Is it doing this randomly, or is it based on music power perhaps? Could you help with a formula to replicate this in Lightjams? The actual colours I can feed in, but would like to replicate the transitions from ELM.

4. In ELM Audio Reactive mode, the transition between A and B changes in duration and speed. Sometimes it stays for a long time on A, sometimes it changes quickly. Under Lightjams control, this is set to a single value.

Thanks.

[Mathieu Lightjams]

The sample project is effectively just to get started. Doing exactly what ELM is doing is left as an exercise to the reader ;)

[a6345634]

Mathieu just one specific question then, I have worked out most of the rest.

In ELM, When the Hue changes on each beat with no fade between colours, has it switched to that mode randomly, or is it based on something? If so, what?

Thanks.

[Mathieu Lightjams]

It's something like:

timer(0, last>0)>25 & music.1 > 30 & music.1.low.avg > 25

Meaning, the music is pretty loud with lot of bass and this effect has been activated more than 25 seconds ago.

[a6345634]

Thank you I'll give that a try. I've just bought a license.

Are there any other video effects I can download? I read on another thread that others could be downloaded.

[Mathieu Lightjams]

There's no downloadable basic/eye candy effects at the moment. You should have about 100 effects right now.

[Mathieu Lightjams]

There are video loops here: https://www.lightjams.com/VJLoops.zip

[a6345634]

Here's what I see - only 13.

[James Walton]

Hi,

If you go the the media tab (on the blue bar at the top of the screen), you will be able to see your media library and import the videos Mathieu has shared, or better still use some of the generative 'eye-candy' effects. To do this click on the '+' icon of each media slot.

Hope this helps,

J

[a6345634]

Great! Thanks. More media now than I know what to do with!

[a6345634]

When remote controlling using sacn is there a way to select media slots >100?

Osc goes up to 255.

[Mathieu Lightjams]

Yes. Just send the media slot number. OSC goes well over 255 as each value is 32-bit.

[a6345634]

I'm using the elm fixture in lightjams. With a power source on the 'media' element.

The power source goes up to 100% at which point it selects slot 100. Elm is in percent mode.

So I think I need to select raw mode in elm. But how do I get lightjams to send > 100 on that fixture?

[Mathieu Lightjams]

Try it. When LJ is sending 100%, it is really sending DMX 255. When in percent mode ELM scale this value to select 1%=media 1, 2%=media 2, etc. It's just for user convenience. In raw mode, the value received from LJ is used as is, without scaling.
