hey, not sure what's going on here. both .duration (which LiSa can't function without, as this is where memory is allocated) and .clear() (which just moves through the buffer and zeros every sample, one line of code) work fine for me. but i'm on OSX, so could be a Linux/Jack-specific issue? not sure how i can help with this, alas! could you provide the shortist piece of code that causes the error, and if there are any messages from Jack when it shuts down, send those on as well? dan On Apr 25, 2012, at 4:41 AM, Kassen wrote:

Kas,
So, I went ahead and updated to 1.2.1.3 last night.
Great, congratulations!
I noticed the error with .loopRec is gone.
Also good, we'll get there :-)
However, my issue persists. Apparently I misunderstand something. Here is a portion of my code:
Ok, let's have a look.
if (func == 1) { //looper.clear(); //Causes a RT error with Jack
Right, that is simply a ChucK bug then, with some luck Dan Trueman (LiSa's "father") will have a look at what is wrong there.
//0 => looper.loopRec; //Does nothing 0 => looper.play; //Record
Here I am scratching my head; does the combination of the code and comment imply that you would like "not playing" to equal "recording"? That would be a interesting way of working, but it's not true. .play starts and stops playback and .record starts and stops recording. .loopRec is a bit like .loop, .loop only works when playing and in that case makes playback loop, while .loopRec only affects recording and sets whether recording -when it happens- works in a looped fashion.
It seems that loop recording begins after I set a feedback level (I'm cool with that), but how do I get out of loopRec mode if not with the commented out line? Also, if I call .clear() or call .duration, I get a realtime error from Jack and it shuts down. I'm sure I'm missing something. Could you point me in the right direction?
I think here might be the reasoning error; the "loop" in loopRec refers to looping in time, not to a signal feedback loop (that may also exist). loopRec means that as the recording position reaches the end of the buffer it'll "loop" back to the start.
Maybe I am reading you wrong, but so far that seems to be it.
Also, if I call .clear() or call .duration, I get a realtime error from Jack and it shuts down. I'm sure I'm missing something. Could you point me in the right direction?
Well, those two are simply plain bugs; things should not shut down over simple function calls. .clear() I'm not sure about, I don't think I ever had to use it, but I really thought .duration was fine. That's strange.
How far does that get you? Or am I misunderstanding something?
Yours, Kas. _______________________________________________ chuck-users mailing list chuck-users@lists.cs.princeton.edu https://lists.cs.princeton.edu/mailman/listinfo/chuck-users
