Mail*Link(r) SMTP               RE>G3 powerbook and MAX/MSP

Stephen,

I'm looking to buy a G3 powerbook as well. Besides its MSP/MAx preformance I
would love to know how good it is at playing large audio files off the hard
drive. If the G3/PowerBook works well for MSP and large audio files, I have
bunches of audio works I'm going to write for it.

Thanks

Just got one 2 days ago.  It seems fine with MAX but I'll let you know
what I discover.  It smokes, though!

I'll forward some advice from David Zicarelli.  From the G3 info they claim
much of the notebook thru-put problem has been solved. It would be nice to
see some actual MSP benchmarks, perhaps even cpu utilization from sample
patches such as a simple thru or the "cross dog" convolution patch.  Any
G3s out there - notebook or desktop ?

Well, my advice is, if a G3 Powerbook is >$5000, spend $2000 on
a G3 desktop and the other $2000 on an LCD monitor. Then you have
a luggable system that will probably run a lot faster
than any Powerbook, plus you can put a multichannel audio
card in it.

This is the solution a number of people have opted for recently.
Historically, Powerbooks have had serious problems with audio
in (for instance, on a 5300, 95% of the CPU is used by a simple
MSP thru patch), and I wouldn't buy one without doing some careful
testing of this performance aspect, to ensure this problem has
been fixed.

If you really want a Powerbook, you should also check out the new(?)
3500, which has a 350Mhz 603 (I think). While the 604 and 750 are
better for floating-point than the 603, the clock speed of this
puppy might make up for it.

Subject: Max 3.5.9 Copy-Pro problems

I just installed Max 3.5.8 on my Powerbook G3.  I requested and got
a System 8 compatible key disk from Opcode (along with $250 worth
of upgrades to software like Studio Vision, Galaxy and Overture, since
new System 8 compatible versions exist).

Anyway, it runs and the CP is fine.

Then, I just downloaded the latest 3.5.9 from David Z.s site.  When
I try to launch 3.5.9, I get the following error message:

Error while validating the authorization count.  This Macintosh
computer is incapable of key diskette based authorization. Please
contact customer support for authorization alternatives.

Yeah, right. Contact Opcode customer support.  I had the redialer
on my phone going all day on Friday and all I ever got was a busy
signal.

David, any ideas?

Subject: PBook G3 MSP Performance

I made a simple thru patch as requested by people on the G3
Powerbook (adc -> dac).  As you know if you've looked at the
DSP status indow, the CPU usage is a constantly fluctuating
figure.  This patch on the G3 shows an average of about
5.25% - I saw occasional spikes up to 10% and low levels of =

4.41%.

Note that this was running Max 3.5.8 (not 3.5.9 - don't know
if there's any difference in CPU usage there, but I'll let you
know when I finally figure out the Copy Pro problems.)

Running the same test on my PowerTower Pro 225MHz desktop shows
that the PBook G3 is actually slightly faster - it was showing an
average around 6.5%.

Note that both of these tests were done with huge collections
of inits running - nothing very scientific or optimized
about it.

Well, for starters, I would look at the papers from the Beat Tracking
special session from ICMC 1994/Aarhus (and follow-ups in more recent
ICMCs, etc.).

I don't mean to sound know-it-all (in fact, I don't), but from what I've
read, getting a reliable beat is tricky. And, remembering that sometimes
two weeks in the laboratory can save you two hours in the library, well,
the rest is left as an exercise for the reader.

Cheers,

Peter

Yes, I love it! Only problem I have encountered was with cd object (cd is
not on scsi chain) David Z has a solution (thanks ever responsive David!)
