Hello, I have create a patch with 80 sfplay~ (they play sampled instruments to create rich microtonal chords). Until I play 6-8 sfplay~ everything works fine, but increasing the number of sfplay~ it happens that after a good start after a few seconds the sound stops. Notiche that the levels of each player are low and the CPU usage test gives me a value of 11%. Any idea of what it's happening? Thank you in advance.

80-sfplay~

no idea, I can start playback on 100 sfplay~ objects at same time without problem. even without poly~ and all that stuff.

I guess you have somethig more powerfull in use, 

so what is forcing that few sfplay objects to stop ?

maybe you use timestretching and other tohowabohu.

which would  change the situation.


6-8 is really low and it must be something else, but i still want to ask: are you using the autoloop function and are some of the samples very short? or do you try to play mpeg or ogg? what a about preload? is preload off and you try to start all 8 sample at the same logical time?

to do it that way, but maybe it is better to build a sampling instrument around play~.

it is not like you had to do it that way, but maybe it is better to build a sampling instrument around play~.

Thank you for your help. It's a very simple patch, with 3 multisliders controlling starting time, level and pan. Each soundfile is preloaded before to be played. I don't use timestretching or autoloop mpeg or ogg. I'd like to show you a screenshot but it's not possible.

I meant I guess it isn't possible to upload screenshots in this forum, isn't it?

Ok, I just figured out it's possible. Coming back soon

Here I am. A few screenshots of the patch.

it is too complicated for me to chase all that send receive etc stuff.

I have a feeling that problem is not letting many sfplayers play,

but the way you trigger messages to them, to read files,

and definitely the whole volume - pan stuff is not well done

for 1 or 0 state you use all that if float thing ?

and bang so many times when that refresh message gets received ?

every note match you again tell players to read same file again ?

I think this is enough hint for you to rethink the structure and reduce it to

is terribly unefficient.

nort think about that multisliders

Thank you, I totally agree, there were many useless things. But now, still with a very basic structure, I have the same problem: as I increase the number of players, after a few seconds they stop playing. The soundfiles I play have an average duration of 30 seconds. I'd also like to point out that I'm using a very old version of Max: MaxMsp5. Nevertheless I can't believe this is the problem.

I can test that for you with max 5 on maxbook from 2008.

simple load 100 instances of sfplay~ and play them.
