Hello guys!

I would like to send data to max (float and int).  
I made a small sketch based on the example of the library oscP5, but I don’t know at all, if we can send several int like that. There is a problem with floats.

I read this in the monitor, I’m not sure it a good sign.

> [2020/3/24 17:31:17] PROCESS @ OscP5 stopped.  
> [2020/3/24 17:31:17] PROCESS @ UdpClient.openSocket udp socket initialized.  
> [2020/3/24 17:31:18] ERROR @ UdpServer.start() IOException, couldnt create new DatagramSocket @ port 12000 java.net.BindException: Address already in use (Bind failed)  
> [2020/3/24 17:31:23] INFO @ OscP5 is running. you (192.168.1.105) are listening @ port 12000

I will put the patch of Max Msp later.

Thank you to all !

@bking Were you able to resolve this issue?

Yes and no.

I haven’t really tried to send data directly from Processing to Max.  
But, as I succeeded in sending data from Processing to Arduino and Arduino to Max, I tried to send data this way. I had a small bug, but it seems easily doable. 😀 😊 😇  
But since my lovely and charming daughter spilled sweet milk on my MacBookPro , I can’t show you the solution right now. I will do it ASAP.  
But the direct solution, Processing to Max, interests me just to compare the fluidity of sending and receiving data between Processing and Max.  
In fact, I don’t know if it’s useful to think about this direct solution.  
In the end, I should send to Max Msp, 10 speed data, 10 position data (between 0 and 2PI) and 10 data informing of the number of revolutions that my virtual engines make, then send this data from Max4live to Abelton Live. (a patch max/msp transformed to be red directly in Ableton Live).  
I already managed to do this with 5 information of speeds and number of laps, but I had small bugs in Live because I had sent too much MIDI information coming from Max Msp, or sent too quickly. 🤔

To settle this, I bought a 15 inch quad core i7, 16 GB macbook from Ram, hoping that Ableton Live will work better. I had a macBook 13.3 from 2014.

Thank you for all your advice and all the solutions you have already given me;) 🥰

Some past Max-Processing libraries that might be of interest. They generally build on using oscP5 / OSC. I’d suggest looking at the most recent ones first (newest first, oldest is last)
