MSP Runs good on my 8100 w/G3-240mhz (Newer Technology).  The example
patches like Cross Dog AB and Forbidden Planet run using just a little
over 50 percent of the CPU Power.  I would guess that this is pretty
good since the patches both have a little note in them that reads "CPU
Intensive"  Any one else have stats of this nature for comparison's
sake?  I'm running the patches via Sound Manager using the 1/8" stereo
outputs.  When I try to use the  Digi Sound Manager Driver to to use my
Pro Tools 442 system (I don't know if this is older or newer than the
Project Card) , MSP becomes very unstable.  I don't think that this is
caused by the G3 card, but by the crappie programming of sound manager
and the Digi sound manager driver.  With the 442 system, I can't run a
digi system init that is newer than 2.9.6 (I actually use 2.9.5 - 2.9.6
is for Motu Products.) I also can't run any Pro Tools software greater
than version 3.2.  So by the fact that you are running version 3.1.1 of
the Digi System Init, you might have better results.

Back in the old days........there was an AV option on the 7100's and the
8100's.  A computer with the AV (7100AV or 8100AV) on the end of it's
name had an Audio/Video card in it that came stock straight from Apple.
These cards gave you a monitor hookup with 2 megs of VRAM on the card.
Also you got  a stereo set of inputs and outputs on RCA jacks as well as
a VCR style video input and output on RCA jacks.  The AV card resides in
your PDS (Processor Direct Slot).  If you have one of these AV cards (or
as in my case an Apple Video Card) and you upgrade to the G3, the AV
card will plug into the flexible expansion plug that hangs off of the
Newer Tech G3 card.  The newer Tech card in turn will plug into the
PDS.  Physically (Not plugged in) the AV card will reside in the center
nubus slot.  It is possible to regain the center nubus slot by doing
some remodeling of the computer case with a saws all.  I did this to my
8100 with excellent results.  When the modification is finished your AV
card will sit horizontally across the tops of the Nubus cards.  I don't
know if a similar modification is possible on the 7100.  If you do
decide to hack up the computer case with some kind of electric Saws All
or something, be sure to remove all the components from the case as to
not ZAp anything with static electricity.  This AV card is not a pro
sound quality card, but it does do OK audio at 16 bit/44.1khz.  I think
it would be fine for getting audio in and out of MSP, especially when
there really is no other alternative, as MSP doesn't support Nubus
stuff.  This is what David Z. wrote me about nubus cards from Digi:
Hope you don't mind me posting this David.  :  )

I don't know how well the AV card will work with MSP, but my gut feeling
is good as a lot of people have these AV cards and are use them for
sound manager recording without problems.  I have not heard of any
problems with the Apple AV Card and the Newer Tech G3 cards as of yet.
I think I'm going to get one.
They are available from Galaxy Hardware Publishing (a great Mac
Resource) for $195.00.

Subject: copy protection, part 8215

The other day I arrogantly claimed that it was impossible to
lose authorizations when downloading the Max update from the
Opcode web site. Well, I think that's wrong--it is possible
to lose authorizations if you download the OS8 version (the
one that works with the 3.5.8 disk) but you have a 3.5 or 3.5.1 key
disk. In this scenario, you could corrupt your key disk if
you run your newly downloaded Max, then it asks for a key disk
(because your drive isn't authorized for the 3.5.8 key), then
you innocently insert your 3.5 or 3.5.1 key disk and some error
message appears. Later you might find that your precious key disk is
completely trashed.

Those of you with old 3.5 key disks, please get them turned into
new ones. It's supposed to be free since the old disks will not
authorize under OS8 or later. I know it's difficult for
people outside the US to do so, but I would like to be able to post
updates for one key disk only to the web site. As it stands now,
Opcode has to maintain an old version of the copy protection just
to prepare new Max versions for people with old key disks,
and I have to make two versions of everything. If I were running
Opcode, I would have just sent new key disks to all Max users
rather than waiting for people to call and ask for them. This
nightmare has dragged on long enough.

Well, yes, that's true, but show me an installation based on
this technique, unless it's one designed to make some point
about the limitations of Max.

No there isn't. We haven't really discussed why symbols are
cool here. A symbol allows any two words to be compared by
looking at a simple reference rather than the entire
character string. This is much faster for the computer to
perform. For instance, when you send the "start" message to the
dac~ object, the proper function to run (the one that starts
the audio) is determined by comparing the symbol "start" with
the symbols in the table of messages that the dac~ object
understands. This comparison can work quickly by looking at
single numbers rather than checking if the text of a particular
entry in the message table matches the text of the word start,
which has to be done character-by-character. In this way, you
could generate a symbol on the fly with sprintf or Stephen's new
object and then pass it to a Max object to execute a message,
without (in the best case) doing any string comparisons
whatsoever. (You might have to do some string comparisons
to store a new symbol in a table, this is known in the literature
on hash tables as "crashing" but I said yesterday I wasn't
going to get into that.)

To create a separate type called "string" where stuff is not
stored in the symbol table would mean that one would
have to symbolize it in order to do anything useful with the
string. My sense is that this issue has only been a problem
due to the bug I just fixed having to do with Overdrive and
symbol creation, and that no one is creating symbol tables
so large as to overwhelm their computer's memory.

Miller Puckette's design of this aspect of Max (which I had
nothing to do with) is in my opinion a brilliant compromise
between dynamism and efficiency, and I don't feel like
breaking it right now, or any time soon. I'm not saying that
it couldn't use a little tweaking now and then, however.

From:    Todor Todoroff 
Subject: Programming question

Hi,
I've got two questions concerning programming external audio modules in MSP.
The second one is specially puzzling. I hope someone might help me explain
the situation (David?).

1) What would be a good practice when allocating memory in *module_new()?
I used (on the ISPW-16) to try to allocate memory first and, if successfull,
I created the object.
In MSP, I allocate memory with newhandle (is this the right method? it works
rather well for two complex modules I wrote, but I seldomly experienced
crashes when load a patch: the computer doesn't crash, but the modules don't
function correctly and I have to reload the patch) and, if succesful I
create the object with
   x = (t_module *)newobject(module_class);

As there is no such example in the manual, I'm wondering what would happen
if I create the object first and then am not able to allocate all necessary
memory. How should I then destroy the object?
Are there any guidelines?

2) I experienced immediate crashes when setting audio on when initialising a
rather short vector of 2048 floats with
   set_zero(float *dest, long int);
in module_dsp(t_module *x, t_signal **sp, short *count)
I don't experience chrashes when this is located either in *module_new() or
in the perform method.
Is there any reason why it shouldn't work?
I tried while (--n) *p=0.0; and it also crashed.
It doesn't crash for n=100 though, so I would like to know whether there is
anay specified limit on the amount of computation allowable in module_dsp()
?
Thanks for any help,
Todor Todoroff

Subject: common MIDI drivers

Hi MAX people,

I will begin by apologising for a slightly off topic question, but this list
has the highest concentration of expert Macintosh MIDI users that I know of.
So here goes...

I've been asked to write some 'generic' (really compatible) cross-platform
MIDI
interface/glue code for Macromedia Director. The code should run with all
'common' MIDI interfaces /
driver setups, etc... I'm trying to write code that can be installed on any
client machine and co-exist happily with whatever other midi software they
have installed.

For the Macintosh I am planning to support OMS and native (direct serial
port, no manager) midi. As Apple is not supporting MidiManager any longer
(as far as I know),
I'm not planning on supporting it.

For the PC I am just planning to support the standard midi driver
architecture.

I have heard of MidiShare, but I'm not sure how common it is.

Does anyone know of any other midi management tools / drivers that are
commonly used?

Any suggestions regarding MIDI management/compatibility issues on either
platform would also be welcome.

ThankYou for your time and bandwidth.

Ross Bencina.

Subject: Re Lin, symbols and strings

The Lobjects are at ftp://arts.ucsc.edu/pub/ems/Lobjects The server was
down most of yesterday. The computing crew just moved the server to a new
machine, and are having some growing pains.

About symbol madness-
The symbol table is an elegant part of Max, with tremdous advantages for
traditional musical problems. But now we are using Max in ways that get
farther and farther afield, and direct string manipulation is required. Lin
addresses part of this issue, providing an input mechanism to get user
input as acsii lists. However, if you connected the right output of Lin to
sprint, you would be abusing the symbol table, creating a new symbol on
each keystroke. That's why the help file shows how to display input with an
lcd object. lcd works, but it is less than ideal for this purpose.

What we need is a message box that users can type into, and that displays
text from lists of ascii. It's on my to do list, but at the rate I'm
getting to things, you'd be lucky to see it by next August. Steve? David?
Anyone?

 There is also FreeMidi which is done by Opcode's rival MOTU. It
theoretically has OMS emulation, but it really stinks, and is not all that
stable (I think OMS stinks too BTW). Maybe Apple would be so nice as to get
of their butts and support/develop a standard (new) MidiManager that ALL
developers could live with. Imagine, a stable Midi manager that would work
with all software that needs/uses Midi... what a concept!!
