I am looking for a way to have two GEM outputs that would show the same thing.
I am doing a show and I need to face away from the projector. I'm using windows, So I extended the desktop and I have one GEM output on the projected half of the desktop and my controls on the other. Is there any way to have another output showing the same thing that I can put next to my controls?

this is intetresting idea. i would really love to have two same outputs - one for live preview and second to projector output.

is there any way?

Bonjour

Yes you can use a second screen like a video projector or a screen

just add a (message box) connected to the gemwin box like this one:

border 0,dimen 1024 768

once this is written and saved

before creating You must click on the nex border box

and then crate

and so on as usual

i don't know if you can have more than two GEM windows try it out

good luck

for now multiple windows with gem is experimental :

i never tried to use multiple windows myself, but i've use [pix_preview] which works fine under linux, you will find it here :
http://artefacte.org/pd/
(and the other externals/objects on these page are great too)

I've just managed a very hacky way of achieving this on OSX, providing you don't need to see each GEM window at the same time.

Run PD under two different users and make sure fast user switching is turned on. Preferably no passwords for each user as this will slow things down.

Each PD under each user will happily generate their own independant GEM windows.

To send data between each instance of PD use [sendOSC] through localhost.

Might not be what most people want, but it works for me.

I have exactly(or almost:-) the same question as agent4068 - need to make two [gemwin] outputs, one on the projector, the other on the monitor, both showing the same thing(in a same time). They both need to be in "fullscreen" mode.

• working on windows -I just "achieved" something like this with some default presentation setup..but...it's quite crap.
  Maybe things did move further from the last post and someone can give me advice how to solve it?

if you are on Linux or Windows, you can run multiple instances of pd, and have a gemwin for each. Then communicate between the two (or more) via netsends and netreceives. I haven't tried this, but I believe it's possible.

maybe a hardware video splitter would do the job?

or if you mean laptop screen, then configure your OS/windowing system into clone mode, or something, and set the laptop resolution to the same as the projector (hmm, not sure what to do if that isn't possible, but worth a try?)

easyest way seems to be the message box with : fullscreen 2 in it connected to gemwin

Y use this for my video projector : very simple and efficiant

do anybody know how to get working pix_preview on osx???
thanks.
