I'm quite new to pd at the moment.

Currently I have a pd receiving OSC messages on port 5001 from Processing, the problem is is that i can't seem to make the messages trigger an oscillator, or anything for that matter.

What is the problem? I'm a bit unfamiliar with the OSC protocol in general, is it a problem with the messages I'm sending in Processing or is it a pd problem?

I sometimes get an error saying "error; trigger can only convert 's' to 'b' or 'a'". I'm just so confused! someone help!

the best way to get help is to post your patch.

yeah, exactly... "trigger an oscillator" is not exactly terminology that most of us know how to deal with

ok so here is my patch, what i essentially want is to send random frequencies to the synth every time the bang is triggered, but i want them to be in the same key. As I said, I'm really new to Pd and don't really know what i'm doing.

Any advice would be great!

ok...well, it's now a much bigger question if you add all that stuff in, but here are some tips:

0 2 4 5 7 9 11

that's what a major scale looks like in terms of intervals from the root note. (sorry if my terminology is off a bit). So, you can write those into a table. Firstly then, create the table:

(you need the leading zero there to tell the table to write from the beginning)

anyway... i have put this in an edit of your patch, so you should see the idea. Also, that makenote was basically not doing anything the way you had it set up, so it has been removed.

As long as you are getting data IN from the [udpreceive] object, then if you just use that gui bang, or preferably replace it with a [t b] object, then whatever comes in will be converted to a bang. There shouldn't be a problem with that. If you need to filter note on/off messages or something like that, then you can just insert a simple conditional after the [unpackOSC] object.

Good luck, and come back when you get stuck again. :0)

This is great! thanks a lot! I'll post back if i need anymore help.

Really appreciate it!

Just another quick question.

Is it possible to use similar methods to trigger bangs that send random velocities and duration's for the note as well?

yes of course.

in those cases, you don't need the table, because the note scale is not important... so you can just use something like

[random 1000]
|
[+ 50]

to give a random value between 50 and 1050 (which you would then use for millisecond timing of the duration)

and you could do something similar for velocity as well..

Remember that OSC messages are formatted like web addresses in a way. Like a tree system with subfolders. You have nothing between your unpackOSC object and the objects your OSC messages are supposed to manipulate. This is where you should use routeOSC or something similar in the same way you would use the vanilla PD object "route". Your bang needs to be listening to something specific (I'm assuming) and right now you're feeding it everything that is coming in on port 5001. It's difficult to troubleshoot further without knowing how your OSC messages are parsed in Processing.

I can include my Processing sketch as well if it helps

The sketch is essentially a 2 balls in window, and what i'm trying to do is use a tangible tracking interface (lookup 'Trackmate') in order to use objects on a acrylic plexi glass surface to control one of the balls to bounce the second ball around the window (like air hockey) triggering sounds in pd every time the second ball touches collides with the sides of the window

i'll include my Processing sketch but i'm not sure whether everything in it will make sense if you're not familiar with the Trackmate initiative and the LusidOSC protocol layer.

here it is anyway, thanks so much for all the help!!!

Alright so, this is what i have in my patch now (included). How would i implement this to trigger random durations in the rest of my patch?

never mind actually, I've done it!
