Help needed with a simple Duplex application

KMaki · November 3, 2012, 11:13pm

Hello, I don’t know what I’m doing. Trying to grasp duplex application programming and started ‘a simple project’ to begin with.

My humble goal is this: I’ve tinkered together a 3-fader touchosc layout for an iPad. Each fader has a set of 5 buttons below the fader. Now, what I want to do is to control currently selected note’s volume, panning and delay column values with these sliders. Don’t know how reasonable that is in the end, but that’s what my ‘simple project’ aims at. I’ve been at it for a couple of nights. Yesterday I got the touchosc layout done, and delved into duplex world. Tonight I’ve gotten the very basics of duplex application working, but I’m still quite lost.

Here’s what I’ve got so far in terms of files.

Touchosc layout: https://www.dropbox.com/s/gh4ryef1ux5uqqm/3faders.touchosc

At the moment I’m just familiarizing myself with the whole Duplex concept, and working to get a connection with A.) touchosc & duplex, and B.) duplex & renoise. Part A.) I think I’ve overcome, because I’ve got the faders kind of working. I was happy when I accomplished that. The duplex virtual control surface gets created all right (ugly at the moment), and the faders are in sync between my controller and renoise. I’ve even got an .on_change function for the faders. Just a placeholder that throws a status message, but at least they’re doing something.

It’s Part B.) I’m having difficulties with. Or rather, the entrails of Duplex are just too vast for me to comprehend.

I’m running into a serious brain melt with the buttons. I’m not quite sure what I’m supposed to do (or what I’m doing right now for that matter), but the problem is that when I press the first button in the top row, I get in response all .on_press functions from all the buttons in the group. This I’m deducing with printouts to terminal. The other buttons are not responding at all. The duplex layout states they are “(unassigned)”. Huh?

What I’d eventually like the buttons to do is to just quickly set the volume/panning/delay to 0%, 25%, 50%, 75% or 100%.

Is there some other on-hands documentation than this post: Creating a simple duplex application, and the duplex docs? I admit I’ve maybe strayed off to areas of tool development reserved to pure genius, but I’d like to give it a shot anyway. I’ve used the post behind the link as a reference with my endeavor. I’ve also skimmed through some existing duplex files.

And. If someone could maybe give a hint on what’s going on with the buttons, I’d appreciate it very much.

Hey, thats funny - I purchased an iPad just yesterday, so finally I am able to support/develop stuff for TouchOSC again

Nothing is “wrong” per se, it’s simply that your application doesn’t tell the buttons where they should be located (set_pos).
It’s not enough to state it in the configuration, you actually need the application to “apply” those settings somehow.

I took your example and modified it a bit: initialization code is now using the new syntax (will only work with recent beta’s),
and the buttons are laid out using the “set_pos” method

Ag! So THAT’s what the set_pos was for. Ok, I think I’ll get this train rolling again. Muchos Gracias!

–EDIT:

Beautiful! Numbers rolling on the editor now. Now must still get the faders to update on line change etc…
