#401 abstraction creation and audio engine

[Anonymous]

I am using Pd version 0.40.3-extended (in a Mac OS X 10.5),

Bug:
Pd audio engine does not start at abstract creation time.

Description:
Here attached is an abstraction to illustrate this problem. When you open it in a "test.pd" window with an argument (say: 440) and initialize audio engine it will run the abstraction "sine.pd" which generate a sinewave of 440Hz.

Now, if you create a new one, with another argument, say "sine 550" it will NOT generate a new sinewave (together with the sine 440) UNTIL you select/deselect it or tun on/off the audio engine.

Thanks!

abstraction sine.pd

confirmed on Pd-vanilla 0.42-4 and Pd-extended 0.40-3;

other workarounds to make it work:
- create yet another dsp-object
- connect any dsp object

turning on/off the dsp-engine is suboptimal as it triggers another bug #2764566 (on linux and Pd-0.40)

bug #2764566 in only apparent on linux with ALSA, right? i haven't encountered the problem using jack. so i still suggest using the dsp-off-and-on approach, since it is much faster than the other workarounds, unless you are really on linux using ALSA.

bug #2764566 is only apparent on linux with ALSA _and_ pd<0.41
i suggest using dsp-off-and-on and and updated version of Pd)
