I've created a plug-in that uses record~, buffer~ and groove~ to take sounds from a DAW, and then play back sounds chosen with random loop points and at a certain (user defined) speed. However, even when you stop the DAW, the plug-in continues to output sound (in my case, the buffer is just repeated infinitely). I turned off the loop$1 command in groove~, but that resulted in the plug-in playing sound once, and then never again even after I went back and tried to repeat the same section of the piece. How can I get it so that once I stop the DAW going, the plug-in stops going as well?

Alternatively, you could use plugsync~ to report the

state of the host's transport and gate the output.

Btw, when I opened the patch, the word 'buffer' was

somehow appended to the two js. objects, creating

errors - opening as text and removing it, made it work

I haven't got time to check this right now, but was
wondering if pass~ might be your friend (though maybe
this only works in sub-patchers...) ? 
Alternatively, you could use plugsync~ to report the
state of the host's transport and gate the output.

as expected,

I had in fact, appended the word 'buffer' to the .js files so as to avoid overwriting the standard Max/MSP JSUI help file examples when I changed them (as I had already done accidently). It doesn't seem to cause any problems on this computer, I assumed it didn't matter what the .js files were called so long as the JSUI objects knew where to go looking for them.

As you have not included any mechanism for stopping the audio with the transport or some sort of decay, if I play sound through your plug in Live and stop the transport - the plug keeps making sound as you say. Logic is a bit more weird than that. It actually seems to work the way you would want it to in my copy of Logic Pro 7.23 because Logic stops all AUs from processing when the transport is stopped or the cursor is not over an audio region in the track the plug is on. So the sound stops with the transport.

As has been previously pointed out on this list a few times, it is currently impossible to get transport information from Logic when your plug is on an audio track due to this "feature" of Logic turning everything off. If you want to play with transport information in Logic you have to use an Aux track.

Or send midi timecode to max and send info back to your plugs with udp (as we currently do it).
