Can anybody tell me what I do wrong with this, when I want to try to read in a stereo mp3 in a buffer~?

By the way: Is this the right way to present a patch (MAX 5) in this forum?

The import message takes one argument, filename. The channels are taken from the header information in the mp3 file.

Thanks for the answer on the way to post here.

The other question: why is a loadbang to the set message that couples the waveform~ to the buffer, suspect? It is a matter of a one-time-bond betwee the buffer and the wave that will stay forever, isn't it?

Second: a simple import to my buffer~ will show the filename in the info~ but doesn't fill the buffer with the MP3-audio. While, of cause, quicktime plays the mp3 without any problems.

If you look at the right outlet of buffer~ you will see it will bang after a file read. If you connect your waveform to this rather than loadbang then you don't need to load anything at start.

As for your import problem, I can reproduce on Max 5 OSX Leopard. Though works fine on Max 4.

Concerning buffer~ import: I'm glad that I don't have to go crazy after all my tries. That it might be a problem from outside.

In the mean time I got a workaround: Give the buffer~ a length (any) at creation. Then override it with the "import -1 2" message. Then it loads in the buffer~. Next have to set the waveform~ length from info~. Then in the end all is in place.

Got your bang thing.
