1.If I open max in live using max device, 'Live' is the only choice I can get for driver in dsp status and vector sizes look like determined by live.

Even after quitting live, I still can't change audio driver. To work on normal max patch, I have to quit max and reopen it.

2.If I open max outside live(before open max using max device), I can have several driver selection including 'Live' and I can change vector sizes.

In first case, dsp doesn't work in the normal patch which created outside live(or not using max device)

In second case, max devices are working fine in live and I can edit them and I can work on normal max patches at the same time outside live.

If I choose 'Live' for driver in dsp status in second case, no more sound~~.

Then what does MaxMSP for audio input selection in live?

Is it possible for grabbing audio from max outside live if I select 'Live' for driver in second case? I mean not through max device.

These make me very very confusing.
I can't find answers anywhere.
Please someone give me clear answer.

Make sure you have b9, we fixed a bunch of audio driver prefs stuff in this version.

If you open a device in the MFL editor, you can only send and receive stereo audio to and from from Live, and MIDI to and from Live.

From b9 on, using the editor won't affect the audio drivers you use when you open MaxMSP normally.

cool.
I didn't upgrade to b9.
Everything is good now.
