hello, so, i've test your patch on my laptop : it work. i compile pmpd on the rpi, test your patch and it don't run. so i can confirm the problem, sending you pmpd binary will not help
basic pmpd example works on the Rpi. it's hard to fully test because most examples need Gem. On the Rpi, the pmpd part of your patch did became unstable. i can see the same behaviors on my laptop if I increase D2 a bit to much. So, your patch is quite sensitive, and easily became unstable. It look like the pi math is not accurate enough to keep your patch stable. when removing few masses, and playing with parameters, i was able to get back to a stable situation. in fact, changing in btch_link_2 rigidity of the link from 125 to 15 is enough to get the patch stable again. (after waiting for few second). btw, i did not understand how a link with 125 rigidity connect to mass weight 100 can not be instable. So although pmpd did not work the same way on my laptop and on the Rpi, i was not able to spot a problem on the Rpi. Accuracy can be the answer. I'll be glad to here from peoples that know more than me on this topic. cheers c Le 11/03/2013 10:31, Julian Brooks a écrit :
Bugger- sorry. Attached now BTW - Please be very careful with the audio level if testing on RPi. It's very loud!

A simple example of my problem: Main patch is: '1.BitChime_pd-list.pd' On my laptop the output going to [s mass1] from within [btch_mass01_sph 0 1 0] in [pd mass_n_link] is between 0-1. On the RPi the same output is between 1-10000. Obviously this has some severe effects on the volume as the pmpd collisions are driving the audio. Apart from pmpd the patch is vanilla. If anyone else can confirm the same behaviour it would be appreciated. (Hey Antoine, just spotted your post, thanks for weighing in) Best wishes, Julian On 10 March 2013 19:22, Cyrille Henry <c...@chnry.net <mailto:c...@chnry.net> <mailto:c...@chnry.net <mailto:c...@chnry.net>>> wrote: Le 10/03/2013 20:12, Julian Brooks a écrit : Hi all, Does anyone have a copy of the most recent PMPD compiled for the RPi that they can forward to me please? I'm having a few issues with a patch that works fine on my laptop but is badly borked on the RPi and I think I've narrowed it down to the PMPD lib that I've compiled. The version I've compiled seems to have built but it's not working correctly. i dit not compile pmpd but i could if needed. But i don't think that i will make any diference. could you explain the problem that i can test here? cheers c The patch runs at about 50% on the RPi (10% on my laptop) so I'm hoping that should be ok. Will report back after further testing.
