Hi there guys!

I've got a problem with the metro object using Pd-extended under OS X Yosemite 10.10.2 (14C1510).

It produces a one bang only when I activate or deactivate the metro objet, enter words only when the object [tgl] has been pressed.

Please run the following patch to reproduce the bug.

metro.pd

#N canvas 629 89 450 300 10;
#X obj 37 37 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 0 1
;
#X obj 37 59 metro 100;
#X obj 37 81 print metro;
#X connect 0 0 1 0;
#X connect 1 0 2 0;

It worked before your osx upgrade?

Here is a quote from Miller Puckette (about slow/fast metro):

I've seen this happen lnog ago but not in the past several years at least - the
cause is probably that the audio driver on your machine is trying to make up
for lost time somehow. (Pd uses audo sample I/O to measure time). If you
aren't usng audio you can jsut turn DSP off to force Pd to use the system
clock instead of audio and this should make the problem go away.
On teh other hand if you need audio I/O on, it migth work to change the
audio drver (e.g., ise jack if you weren't before, change audio hardware, etc.)

Maybe pd has stalled because your audio device is not connected properly (to pd).... check "media settings".

many thanks for your very quick answer. and yes you where right. However, I found out the actually problem wasn't the audio driver, yet I dint't choose any audio hardware.

I din't know that Pd counts the time through audio sample I/O.

Many thanks!!
