audio interrupts when editing patch

Hello everyone,

I experience short audio interruptions when I'm editing a patch, like adding or removing objects, while audio is running.
I tried setting the IO vector to minimum (64 samples) and scheduler in overdrive to off, but I still have very short interruptions (though they slightly shortened).
I have this problem when I'm using my external sound card and when I'm using built-in output, so it's not a sound card problem.
Also I don't have this problem in PureData, which is running at a vector size of 64 too.
Is it my computer that is getting too old ? :(
Or is there any other trick that I'm unaware of ?

Thank you,

Hugo

Hi
This is entirely normal behaviour, as MaxMSP recalculates the new DSP chain.

A newer machine with a good audio driver will allow you to optimize the signal vector size.

Actually you're right and pd does it to, but only when you try to load external objects or your own abstractions. However when you add a new built-in object there's no click.
How come I never noticed this before ?
I'm still going to do some clean up on my computer because it has been a bit slow lately.

Anyway, thanks for your answer Brendan.

Look in the Max preferences (in the Max menu). "Enable Mixer Crossfade" should be on, to eliminate this dropout.
