Hi Folks
Here's my set up
1.25 dual G4 1.25ram 200gb lacie 800 firewire drive OSX 10.3.4
Motu 424 card 2408 III interface
Magma 7 slot chasis with 1 powercore 2x Uad-1 cards
Logic Pro 6.4.2
Now here goes I've got 20 tracks running and quite a few plugins but none of
the boards
are overloading or anywhere near overloading I was occassionally getting a
message that
the Core audio disk too slow ! but I even put up with that crap even though
I can run
cubase on a dual 500 with the same amount of track with no problem.
I started to do a radio edit of a tune that was readfy to mix down to tape
(old revox) I cut
up the track and deleted the regions getting a box asking whether to keep
the automation
or not (I have tried doing this both ways keeping and not) then I move the
regions to the
edit point and get asked if I want to move the automation yes and everything
fine ecept
that the automation at the end of the track does not move, I have tried
everything with no
success I've tried editing the automation and that doesn't work neither.
Then I looked a Logic on line help but that was not installed so I
reinstalled the whole of
logic first with Platinum then Pro but still no online help then tried
playing back the tune
and it gets the disk too slow and crashes all the time.
I've removed all the automation every plugin taken the Magma chasis and the
powercore
uad-1 cards out of my machine so all I am left with is a song with 20 track
that are 24bit
41000 sample rate and guess what it gets to the 18th bar and gives me the
Disk too slow
and crashes, if Logic cannot play 20 tracks back on 1.25 dual G4 it is not a
professional
peice of kit but Flake-ware
Has anyone any ideas I'm about to reformat my OSX drive and reinstall the
whole system (
I really enjoy the productivity that I have with this system this the second
time I'm
reinstalling the system)
TTFN
Subcoustic
searched the faq .. I forgot how to extend the recording time of an audio
track
any help would be great
thanx

I'm guessing you have your audio tracks on the firewire drive. You shouldn't
have any
trouble running that many tracks on an internal drive. Does your G4 have a
FW800
interface or is it standard Firewire? Also, do you have any other firewire
devices attached
to your system? They can slow down your available bandwidth and cause
polling
interruptions in your disk stream. Have you increased the Disk IO buffer to
the largest
setting?
Try copying the tracks to your internal drive and see if that helps.

Hi,
just press "a" to get to the audio record settings window and
change the time limit by
either changing the amount of time,or unchecking the box that limits it.

If the G4 Dual 1.25 is the older MDD rather than an FW800 Model, then
your FW800 drive is only going to run at 400 max.... which is roughly
50MB/s same as old fast scsi II, or Slightly slower than ATA66. Only
with the very last generation of g4 machines is FW800 relevant., also
if you have an FW400 device connected to the FW800 Buss, it will run
the bus at 400 not 800, in much the same way as SCSI only ran at the
speed of the slowest device connected /.
it should still easily cope with this number of tracks though, hell My
Old (before I got the G5 last year) G4/500AGP could run 50+ tracks of
44.1KHz audio
Logic can run it easily... Hell on My G5 System it can run well over
100 tracks (not that i ever use that many)
So the question should not be what's wrong with logic, but what is
wrong with your system, and how exactly have you set it up
incorrectly....
Perhaps if you gave us some idea about which continent you're on,
someone more Mac experienced, and local to you, might consider helping
you out on a practical basis.
Little things like making sure file vault is not active, that the Disk
is Formatted into Mac OS extended, and at appropriate block sizes (for
example, some Glyph drives are NOT set up for Mac use "out of the
Box"
but require formatting into an appropriately efficient
configuration....
I fail to understand why ANYONE uses Firewire Disks for Audio
Tracking..... they are pretty much ALL slower than the internal Disk
drives can be.....
For example.
the earlier MDD dual 1.25 had ATA 100, which = 100MB/s maximum
transfer....
which okay, FW 800 can pretty much match......... except that this
machine only had FW400, which is half as fast! at only 50MB/s
the Later Dual 1.25 FW800 series had true FW800 alright, but also had
both ATA100 and ATA66 Internal busses, and supported up to four
internal hard drives, 2 on each ATA Bus, and all of which outperformed
FW400. with the ATA100 easily at least matching FW800, possibly in
some circumstances, surpassing it.
Indeed, with the G5, and the advent of SATA150 , the internal drives on
Current Power Macs now FAR outstrip Even the best that FW800 can
offer.... by some 50% or so.
Anyway, back to your "issue"
As someone else has mentioned, make damn sure you do NOT have nay other
firewire devices sharing the buss.
Also, experiment with the larger Disk buffer settings, but on mix
down, assign a larger Buffer value to the PCI424-2408Mk3, as the
latency is irrelevant on playback..... up the latency and you may find
that the latency loading was causing a problem, and that now everything
runs smoothly.
you MIGHT also find a problem if you are using a LOT of the Resources
on your DSP cards , as this can use a fair bit of the PCI bandwidth,
which your PCI424 also requires... however, if you're not pushing them
to the limit, then it's unlikely to be the culprit...
Are you using EXS24 and are your samples stored on the same disk as
your Audio files????
this too can cause problems, it is usually best to keep the Samples and
Audio recording on separate Disks, on Separate Busses...... So Audio on
ATA100, and Samples on ATA66, or vice versa, and then Back them up to
the FW800.....
Are you using the EXS Virtual memory manager?? I have found this to
cause me no end of hassles in OSX, so I turn it off and let OS X's
native management take control...... which I find more reliable and
robust, but then I have 3.5GB of RAM, so it matters less I
presume/......... ( I also use EXS in 32 bit sample storage mode not
24....)
Also, if you're using a MDD 1.25 G4, with 4 PCI slots AND AGP, then Why
are you using the magma??? All these cards should fit inside the Mac
anyway, removing the possibility of any Expansion Chassis problems
being relevant.
(I'm open to being told there is a good technical reason to do so mind
you.,....;-) )
But I can assure you Logic plan play more tracks than your hardware
can.... So Don't go blaming it for ALLl your problems..... ;-)
just the ones where it IS at fault...... (Like not Directly supporting
ADAT 9pin Sync for clock sourcing ..... )

I think you remember incorrectly. Fast SCSI-2 was *5MB/s*, not 50.
Ultra-Wide SCSI was 40MB/s, then I believe they jumped to 80 and then 160
and then 320.

SCSI-1 and SCSI-2 regular flavours = 5MB/sec
SCSI-2 Fast = 10MB/sec
After that I stopped using SCSI, and lost track...

These of course are all theoretical max bandwidths. I have a 867 Mhz
G4, which I believe has ATA interface that should be much faster than
FireWire 400
but the IBM drives I measured permormed worse than the latest LaCie
FireWire I bought. As I haven't had the need to run more tracks than
the internal IBM drive can give me, I haven't tried it in real life
situation to see if I could get more tracks out of the FireWire drive
than the ATA drive.

Thanks for the input Max
Ive been using Macs for about 10 years
the Mac is a FW800 model I'm runnig firewire drives because Emagic
support in the UK recommend that I use Firewire drives ( did ask
about all the alternatives as I'd just had problems with a Adaptec
39160 system that after enquiring more I found out to be a not
recommended SCSI system to use with OSX ) I do have firewire 400 but
it's not on the same buss as far as I know, I've talked to the local
Mac tech guy who's looking into finding out whether the FW800 buss
is actually used by the FW400 ports ( which is a bit of a cheat ) I
have reinstalled a new system and reinstalled logic and uad-1 and
powercore the logic help has not been installed and the FW400 taken
out of the system and still with no plugins used and 20 tracks playing
back (7 or 8 playing back at the same time) it gives me the core audio
overload. I've talked today to afew friends who use logic and all of
them are coming up with the same conclusion that Logic is not installing
correctly on my system, I'll have a look at the file vault tomorrow as I
forgot to check it and for the record these are all audio tracks that
full lenght and there's just 1 midi track no virtual instruments technical
reson for the Magma is that they seem to run with less problems in a
chasis no pops and crackles when pushed abit and also I am thinking of
getting another card aswell, if you come up with anymore ideas I'm willing
to try them out.

Do I undestrand you correctly, you have "File Vault" enabled? Turn
it off.
Also switch off journalling on your audio drives (only leave it on on your
system partition).

Hi Peter
No I don't have file vault enabled never have, I installed 6.4.2 on my Dual
500 in the office today and have the same problems with no online help so I
think I've got a duff installer and support in the UK also think that it's
something to do with the intallation, so their send me a new intsaller,
fingers crossed.

It does seem that the 6.4.2 installer does not copy the help files across
from the 6.4(.1) install. It is possible to copy them manually if you wish.
I doubt very much that this is causing further problems with your
installation - but you are obviously getting that anyway.
Have you tried running your session from the internal drive rather than your
Lacie drive? I've found all manner of problems with them...
Also have you tried playing back the song on the built-in hardware, rather
than your MotU?
BTW: the FW400 and FW800 are on the same bus. Quote from the Apple
documentation:
"The three FireWire ports share a single power supply that can provide
up to
15 watts total. The three ports are all on the same FireWire bus and can
connect to up 62 other FireWire devices."
And also (I know you're having problems without this in the setup), I would
be very surprised if you got your MotU and PowerCore and UAD cards all
happily playing together. There's a _lot_ of load on the PCI bus here, and I
would expect you to get all manner of pops and crackles with it.
That'll do for now.

The best of times to you all...
