hi there:

there has been this strange behavior on loading up my dsp abstractions that is bugging me for the last few days and i finally worked out a way to describe and reproduce it and i wonder if anyone can help to explain.

to reproduce it:

1. make a example abstraction like this and call it say, test.pd:

[osc~ 440] | | [*~ 0.5] |
|
[dac~]

#N canvas 0 0 450 300 10; #X obj 150 93 osc~ 440; #X obj 177 159 *~ 0.5; #X obj 205 206 dac~; #X connect 0 0 1 0; #X connect 1 0 2 0; #X connect 1 0 2 1;

2. make sure the compute audio is on before loading [test]

3. open a new patch and load [test] as an abstraction. at this point,

shouldn't i be able to hear the [osc~]? but i don't! however, if i load another [test] in the same patch, i can then hear [osc~]. if i load up [test] as a patch, it works fine.

so, somehow, when [test] is loaded for the first time, nothing happens. but in the second time, it functions as expected. can anyone help to explain?

i got the feeling that its something really basic about Pd that i don't know yet.

many thanks
