That very well could be.  But I've also heard that getting something
like a ms accurate clock to run under Windows 95/98 is ridiculously
difficult, where as with NT it's not.  But like you, I'm
just guessing...

I'm using MSP 5, OS 8.1 and a G3/233. To make sure having no corrupted files
I reinstalled MSP again, and also tried booting with the standard extensions
configuration. Max Version is 3.5.9. A crash can be produced with a simple
sfplay~ patch: open a soundfile, then play it and send the open message
again while the file is still playing. The screen will freeze immediately.

Ok, this could be prevented by closing each soundfile after playing is
But also a crash occurs randomly when playing several sound files at the
same time and a preload  message is sent to another sfplay~
object and after a certain time delay a play cue command is sent. This seems
to work more safe when that time delay between preload and play is longer
(some seconds).
PowerPC access exception at ...          sfplay_convert +0000C
What causes that crash ?

I'm using an AMIII card but that will change soon.  I will either use a
digital time piece or smpte slave driver or equivilent to drive the digital
sync mechanism.

I haven't used SMPTE and Max together ever so I was a little concerned
about trying to trigger a sfplay object using SMPTE.  But I understand you
now and will let you know my results.

There are some other serious reasons for choosing NT over Win9X, like the
fact that NT deals with multi-threading in a much better fashion. Win9X is
really pretty much of a joke as far as OSes goes, especially when you
consider multi-tasking, etc.. I guess in some ways it might be a bit easier
to do some real-time DSP with Win9X as it seems that almost any process can
gobble all the resources it wants. Then again, if the OS decides it is now
a good time to transfer something to the virtual memory (which it does all
too often), there goes another glitch in your audio.

 From my understanding, this is going to change. Win98 is the last of its
breed, as NT 5.0 will merge into the next generation 'Windows for dummies'
OS (in a similar way to Apple's old plan to merge Rhapsody into MacOS). For
the average Wintel user, this means they will have something to look
forward to in their next upgrade (unlike Win95 --> Win98), but they will
still have to deal with all the similar crap that exists in Windows today
(like the hundreds of system files, the insane system registry, crappy
hardware, Plug 'n' Pray... you get the idea). I wouldn't be surprised if
this is what convinced Apple to get off their asses and start to deliver a
real OS (Rhapsody/OSX). With a little luck, Apple will actually deliver
what they promised in the last developers conference. Maybe at the same
time, they can convince someone to trash and rebuild sound manager (from
scratch please).

If your looking for a good LTC/VITC to MTC converter there's WIF from German
manufacturer Rosendahl-Studiotechnik. It supplies MTC and also SuperClock or
wordclock at high precision so it's a good replacement for the smpte slave
driver at half of the costs. I heard the devices will soon be sold in the
States by Aardvark. If you are interested send a mail so I can give you some
more information.
But remember MTC triggering doen't control the speed of the audio. There has
to be always a combination of triggering and controlling the sample clock.

Just for the record, I don't have a Korg 1212 (or any other DSP card).  I'm
on the road at the moment, so I can't check whether I have the "ATI Driver
Update" extension.

Thanks for looking into this.

You can use the click on the command-click on patcher background trick to
lock and unlock patchers.
This has become my perfered method since the close window and edit icons
are right next to eachother and their keyboard shortcuts, command-w and
command-e, are also right next to each other.

Subject: Window characteristics of many patchers with send and receive

Hello Maxers,

anybody have tried the tip for hide and show windows on page 31
of Addendum?

(look in the book for follow my instructions)
I place a receive messages_to_thispatcher in somes of my patchers.
So, with the send messages_to_thispatcher in a master patcher I can
control the status of all my other patchers. It work very fine when
I have only one patcher open.

But, if I use two patchers (or more), only one patcher respond to the
message?!? (I think it's the last patcher that I have open)

The syntax of my send and receive object are ok because when I send
a close message all the windows closing immediately.

Anybody have ideas or comments?

Thank you
