Hello,

I'm new in using OSC. I managed to send OSC messages via UDP from Pd to Reaktor (I use Pd to retrieve datas from hardware controlers like Joystick or iPad to send them to reaktor to drive my instruments) using mrpeach objects like [udpsend]. But as UDP isn't as relible (it can loose infos in the path) I would like to use TCP protocol between Pd and Reaktor.

Is it possible and if yes how can I do that ?

Thanks

have a look at [mrpeach/tcpsend]

Yes I tried it but I can't connect it to a specific port. When I conenct it I have no error message but it doesn't keep the connexion. I'm a real newby in networking, when one speaks, say, about port 9000, is it the same port 9000 for TCP or UDP or each protocol has his own port ? Meaning that there is a TCP 9000 and a UDP 9000 ?

I thought it could be a port conflict, so is there a way to know what ports are used ?

maybe this hepls:

Well it doesn't change the issue. It works if I use it the first time I open Pd right after having started windows. After that it can't connect even if I click on disconnect and close and restazrt pd

hm, sounds like a OS or network problem.

I went a bit further :

If I only put a [tcpsend XXXX] on the patche it can't connect, but if I add a [tcpreceive XXXX] in the same patch, it works, it connects.

If I put an [tcpsend XXXX] but with an [tcpreceive YYYY] in the same patch it doesn't connect, the same as if I only put a [tcpsend XXXX] alone.

It's problem for me because afterwards I want to send all of that to Reaktor and Reaktor will not connect in reception is there is already a tcp receive on the same port already opened somewhere on the computer.

I don't have that issue with udp.

My patch gets datas from a joystick with [joystick] and is dedicated to send those datas to Reaktor.

I wanted to do it in tcp instead of udp because some datas can be lost in udp.

I'm not really sure what the problem could be, but are you running Pd and Reaktor on the same machine? Because if so, I've got to think data loss wouldn't really be an issue. Also, UDP is faster than TCP because there isn't that check for the data loss. From a control perspective, that's a plus.

Right, first open a port then you can connect to it.
you can use netstat to find (Reactors) open ports to connect to.

I didn't know that info, so I'll remain with udp, tcp seems to be dedicated to net performances.

Anyway it works perfectly on udp and now I can use 16bit control datas in Reaktor instead of 8 bits/128 values of the Midi standard. That's cool.

I've tried to do a sampler that can play a sound file by "brushing" brushing on it with the joystick, it's quite complicated in Pd and I"'m not sure Pd is made for this.

sounds like you want to use [hid] and [readsf~].

Why [hid] ?

you mean [hidin]? It obviously tends to crash pd !

I checked it, it seems to output value in 8 bits, the joystick is 16bits.

Also, it oesn't output values on axis like 0-255 but 127-0 and 0-127, even not negative and positive values.

What is the interest of [hidin] ?

And yes, it crashed pd twice in 10 minutes !

I think sunji just missed that you are already using [joystick]. If that's working, you don't need to use [hidin].

Take a look at Help Browser -> 03.audio.examples -> B07.sampler.pd

Well, I looked a bit into [hidin] it seems to be cool but it's also very unstable, at least on a PC. I've seen that it saw my wiimote, but the wiimote is on bluetooth... Can it get datas from the wiimote ?

No. I think people just use things like GlovePIE to send Wiimote data over OSC to Pd on Windows.

Gosh ! My poor heart started to run faster when reading the glovePie mention ... but soon returned to its cruising pace when I understood it is a windows only stuff (I'm on Linux)... thanx anyway.

There is [disis_wiimote], but I don't know if it will work for non-L2ORK version of Pd.

Thanks Maelstorm ! I had some issues with wii abstractions that were aivailable, then not anymore, then again ... I'll check this stuff soon.
