Live API Question (Self aware device)

TheAlphaNerd · Post by **TheAlphaNerd** » Sat Aug 14, 2010 5:09 pm

So I'm working on a patch that displays the currently playing track name in a jitter window. At the moment I have hit a bit of a wall in design. I want to move this patch closer to the realm of an abstraction, specifically I want to be able to drop a device on to a track and for the device to know what track it is on. I am unsure as to how to poll this from the live api.

In case I was not being clear enough, I want to know how I would go about polling the live api to find out what track a device is currently on, so that I can use that data.

This is my current code fwiw

So that code definitely works to figure out the track number... but the problem I'm thinking about now would be what if the track is changed. Currently the device is only activated by a loadbang, so if the track orders are changed the device will no longer output the correct audio. I've been trying to find a way to get this information from a live.observer function, but still can't find the right way to do it (or if there is even a way). Should I keep trying to figure this out, or am I better off using a qmetro and some sort of comparison equation to keep track of the current track? My only worry is that I would be putting uneeded strain on the cpu with this metro... especially if there are going to be multiple copies of this patch running... I also worry about potential syncronicity problems of using the metro... perhaps I should sync it to the metro I'm rendering at... hmmm....

Just try it. The middle outlet of live.path follows and reports ID changes. So if you move a track, the ID changes and triggers the calling of the path in the live.object.

I did, and it just did not seem to work for me... the live.path object was not following the movement... I'm going to read up more on the live.path object, but in the mean time I made it work... but I really don't like the overhead required to do this simple function
