hi miller,

i promised to send you this one: it appears that the pd subprocess ony starts to compute (even
messages) when audio is switched on in the subprocess. if it was
switched on once it may be switched of safely afterwards.

a workaround for now is this in the subprocess' patch:

[loadbang] | [t b b] | | | [; pd dsp 1( | [delay 20] | [; pd dsp 0(

thanks for taking a look.

Max
