Hi all,

Since I'm a new comer to the Max environment, I met a few problems when setting up the midi controller to Max. So I would like to ask for your opinions.

Currently I have a midi keyboard connected to the Max patches to make the notes in, but there is a huge delay between the keys you hit and the sounds Max could make. Here is my configuration information,
WinXP, Intel 1.4G, 256Mb, Max/MSP 4.5.2 with Jitter, Roland D5 keyboard(usb). The simplest Max patches I used to test contains only notein followed by noteout object, and that would also cause the delay problem.

I would like to know whether you have such problems, and if so, how you solved them.

Thanks a lot.

Hi Sherie,

try fiddle with the "Max Scheduler in Overdrive" and "Scheduler in Audio
Interrupt" settings in the Options > DSP Options menu, and see if they
make any difference. If so, you can check out
MSP45TutorialsAndTopics.pdf page 36 -> for more details on the settings,
in particular the two options mentioned above are explained further at
page 41.

Best,
Trond
