banfangled

I'm on a PC, Win XP, I have an m-audio delta 44 soundcard, and I use the asio diver. I like to use a 48kHz sample rate. Here's a weird thing that happens in Max: as soon as I add a [midiin] object, my audio sample rate sets and locks at 44.1 kHz. I can't change the sample rate until I restart Max again, even if I close the offending patch. Sometimes the DSP Status window pretends to give me an option for a different sample rate, but if I select 48kHz I get can error -995 saying the sample rate can only be 44.1.

It seems like an obscure error to me, I'm just wondering if anyone has come across similar behaviour.

Does your M-Audio thing have a program that sets the sample rate as well? It could be (a huge guess) that when you activate the M-Audio thing by using the MIDI inputs it makes the whole thing conform to the same sample rate. Have you tried 88.2 kHz to see if it has the same effect? I ask this because CDs are 44.1, DVDs are 48, and most ultra-high quality stuff is 88.2, not 48. Is your MIDI interface the same box as your Delta 44? If not, maybe you could also try setting the sample rate of your normal built-in sound card to 48 (or 88.2).

I have had my sound card control my sample rate, although it's a PreSonus FireStudio. Usually, what happens is that I start MaxMSP at 88.2, then accidentally open up iTunes while my PreSonus is set to default output (rather than built-in audio). iTunes causes the PreSonus card to switch to 44.1, which then causes Max to go to 44.1, which then causes a huge pop in my speakers. So, also check to see that initializing MIDI isn't also initializing some other program that could be superseding Max's sample rate.

The M-Audio does have a control panel, but Max overrides it. If I have the M-Audio control program open at the same time as Max, I can watch the sample rate change when I change it from Max.

My issue is directly related to the [Midiin] object. If I start a brand new empty patch, with nothing else open, I can change the sample rate at will - 48, 44.1, 88.2, 96, etc, no problem. But, as soon as I add a [Midiin] object, the sample rate locks to 44.1. Even if I close the patch, the sample rate is locked. I have to quit Max to regain control again.

I suppose it's possible that it might be initializing some other MIDI program, but I have no idea what the other program may be.
