Subject: stuff about the Korg 1212 I/O

1. We have a report that the combination of a G3 running System 8.1, an
extension called "ATI Driver Update" that is probably used
on G3s (that have ATI "Rage" video cards), but doesn't appear
to be necessary, and the Korg 1212 in use with MSP results
in what I've dubbed the "problem from hell" mentioned here
by Kevin Walker a few days ago in which all Sound Input sources
disappear from the System. Replacing the System file usually makes
the input sources reappear. If you disable the ATI Driver Update
extension, it appears that the problem from hell will not
happen. There may be other ways of acquiring the problem from
hell, but it's definitely happening to machines with this
combination of stuff. Whose fault is it? I have no idea. Korg
claims they saw something like this happening in 7.5.3 and
traced it to an Apple bug.

2. I/O Latency figures for the Korg card under certain conditions:

Using the forthcoming ASIO driver, the I/O latency is 37ms.
Using the default "offset" setting of the MSP audiodriver,
the I/O latency is 49ms.

Here are latencies measured with other "offset" settings,
you change this setting by sending the message

; dsp driver offset N, where N goes from 0 to 7.

offset = 0: latency 95.6 ms (MSP 1 old version default)
offset = 1: latency 14.33 ms, bad audio distortion
offset = 2: latency 25.94 ms
offset = 3: latency 37.55 ms (same as ASIO)
offset = 4: latency 49.16 ms (default)
offset = 5: latency 60.77 ms
offset = 6: latency 72.38 ms
offset = 7: latency 83.99 ms

Those darned kids are at it again. No, there's no way to do this,
but it's not a bad idea for something to add to thispatcher. I think
that padlock is going to have to go away eventually anyway. It's a
nasty hack.

Christopher Murtagh is concerned that the naked pursuit of profit
will distract my attention from the support of Max and MSP
on the Mac platform. I am not doing the Windows port myself.
I don't know how to program Windows, and I'd like to learn as
little as possible about it. However, just to provide Mr. Murtagh
with even more grounds for anxiety, I will mention that Max
and MSP are not the only things we're doing on the *Mac* platform,
and I hope that these other things will appear over the next
couple of years. But long before that, you'll see new Mac
versions of Max and MSP.

I have successsfully used the icube Far reach in an interactive
installlation. It does require careful placement to minimise the
clicking noise.
I placed it near the entrance to the installation space and behind a
curtain so that once you passed by the curtain the clicking was barely
audible - also the sounds that it triggered were louder than the
clicking - hope this helps.

Thanks David for easing my WWD (Windoze World Domination) paranoia
(amplified by the fact that I have to sit in front of a Wintel machine all
day in a department that used to be all Mac). I'll just crawl back into the
closet with my Linux box, G3s, iMacs and a couple of MacAddict magazines.

Has anyone actually done this?  I remember this being explained to me
before the advent of DAT w. timecode, but I never saw anyone actually do it.

This would give me clock sync but how would I find the initial offset.....?

Do I grab the smpte time and start my sound file playing at that moment?
Which would probably cause some predictable delay which I could account
for....

Has anyone tried it and can give me their thoughts about building a max
patch?

Thanks -

i use a dummy patcher with send objects to the main patcher
this gives you a separate track for each dummy

You can trigger the audio file with MTC (derived from SMPTE or VITC) and
this works pretty exactly even when triggering several sfplay~ objects at
the same time. But to synchronize the sample clock to your external
equipment you need a digital audio card. What audio card are you using and
to what source or device you want to synchronize MSP ?

hi all,

here's some info that i just received that will be of interest to those of
you
with PowerBooks in the UK who (like me) are waiting with bated breath for
decent
audio in/outs.

for other territories, there are links to distributors on DigiGrams web
page.

I think some may be jumping to conclusions assuming the motive for porting
MAX to Windows NT is just profit.  I'm not as familiar with Windows, but my

understanding is that NT is server software, designed for running networks.
It's nowhere near as pervasive as Windows 95/98, which is the desktop PC
operating system that's Microsoft's version of the Mac OS.  It's the
market for software that runs on Windows 95/98 that's ten times larger
than for Macintosh, although the number of users of music software is
about the same as for Macintosh.  Besides that, professionals and academics
still strongly favor Macintosh.

But the announced port is to Windows NT, which is software primarily used
by businesses to network their Windows 95/98 PCs.  Except that high end
post production houses are migrating away from SGI and Macintosh to NT,
for reasons I'm not privy to.  But I do know that many high end animation
and video editing packages are being developed for, or ported to, NT.  So
it
seems more likely to me that the reason for porting MAX to NT is to go
after that market.  The motivation for which might have more to do with
wanting to be in the forefront of film/video/multimedia production than
pure profit.  Although those people do have a lot of money to spend,
besides the technical sophistication to appreciate MAX.

Of course I could be way off base here.  Just a theory.  Maybe David Z.
will let us in on his thinking.

Martin, are you using the current version of MSP? I think this
bug was fixed long ago.
