Hi,

I would like to scatter sound events uniformly in time over a span of
several hours.

I am using a Mac (Csound v6.11) and using the CsoundQt front end (v0.9.5.1).

The below code will work fine on the first run. However, when I stop it
fully and then try to run it a second time, it will hang up the computer. I
then have to force-quit CsoundQt.

If I make the TOTAL_DURATION macro something like 120 seconds, it will work
every time, without hanging up the computer.

I have tried a variety of things such as delaying the start time to give it
more time to fill up the event queue, using an e statement with a
sufficiently long duration, making the i10 score statement duration longer
to give it more time to fill the event queue, and tweaking the f0 duration.

I have realized that if I wait about 1-2 minutes before I run the .csd file
again, it does not hang up the computer. But waiting like that is not ideal.

I am wondering if I need to clear the "event queue" somehow before I run the
.csd file again? Will you please assist me on this question?

Thank you!







sr = 48000 
ksmps = 32 
0dbfs  = 1 
nchnls = 1

#define TOTAL_DURATION #18000# ; Total duration in seconds.

instr 10
	itimes = $TOTAL_DURATION/3 ; Number of events to produce (i.e., 6000).
	icnt = 0
	loop:
		istart unirand $TOTAL_DURATION ; Distribute sound events uniformly within
0 to 18000 seconds.
		event_i "i", 100, istart, 3
	loop_lt icnt, 1, itimes, loop ; End of the i-time loop.
endin

instr 100
	asig oscil 0.1, random(400, 800)
	kamp linseg 0, 0.2, 1, p3-0.4, 1, 0.2, 0
	asig *= kamp
	out asig
endin




f0 18000

i10 0 10

I tried it here on commandline and found I could use ctrl-c to stop
Csound. That i-rate loop does take a while to run though before sound
commences.  I don't see the typical csound end of performance
information though after ctrl-c.  Seems like it might be an issue with
CsoundQT?  Have you tried run in terminal?

Hi,

I have no problem stopping and restarting the csd in CsoundQt as many times 
needed on Linux (both self built from git). I hope to remind and try on MacOS 
- there have been alsom similar reports on other cases that starting csd 
second time hangs CsoundQt on some cases.

greetings,
tarmo

Thank you for the tip. It seems to be working in the terminal.

Thank you for your reply. I tried running the example .csd file in the
terminal and it worked. However, I then ran the example .csd file and
several more similar .csd files in CsoundQT and had it hang only once. This
is strange, because over the past several days it had been behaving as I
described above (i.e., hanging on the second run). I am not sure what has
changed.

i'd say, if you don't need csoundqt's widgets, for a job like yours 
running csound via terminal is always the best choice.  as you may know, 
you can also do it from inside csoundqt via the "Run in Term" button.
