Logic 7 clips too easily

Does anyone know why this might be the case? With Logic 7.1 on a G5, Audiophile
2496 PCI soundcard, I find that the output clips really often using plugin synths - either
Logic's own, or others. I'm always having to turn down the level of tracks in a way I
don't seem to have to with Reason 3 (on the same computer). What I mean is that
if i have say a beat coming from Battery, and then add a bass off one of the Logic synths
it's more than likely the output will be a bit distorted if I don't turn down the tracks'
levels. Could it be to do with the level settings in the Audiophile's own
control panel?

No. not the audiophile. Just turn everything down - most of the presets etc are just too
loud - in a 24 bit system you don't need to run everything at full whack. I think the
thing to do is to have a lower individual outputs and leave the master at 0dB. Logic isn't Reason. There is more scope for getting things wrong (and right).

This has nothing to do with the Audiophile and everything to do with the software summing.
If the synths give an output close to full scale then naturally mixing two or more sources
together will result in overloading the output. A few things to do is to switch to Pre
Fader Monitoring of the Audio Tracks (although overloading a channel won't always result
in clipping due to 32-bit float yada yada... it's just easier in the long run) and get
used to not cranking the hell out of every plugin. Is Battery giving you too hot levels?
There's a volume knob. If you turn every synth down by about 6 dbs (internally) you will
have much better mixing levels.
My 2 öre.

I'd love to concur but I'm not sure what you mean exactly..
I had a look in
the pdf manual, and it says if you click-hold the send slot, the bus menu will open. I did
that and both post and pre are greyed out.. Why would that be?
And any more info on
the pre versus post issue? The printed manual suggests that post is best for most
situations. I don't know, I'm clueless.
Edit: the bit I read was
obviously about Aux Sends, I've now found the Pre Fade Metering option in the Audio
menu... Still not sure what it does though. Can't seem to get the principle into my head!

Pre Fader Monitoring
does exactly what it says on the tin. It monitors the level of the track regardless of
where the channes fader is. ie if you've got a signal hitting 3.4 (in POST fader
monitoring) then you could pull the fader down to -3.4 and you'd have a 'clean' (no
visible clipping) signal. This would add up over time though to mean very little dynamic
range in your mix.
Pre fader metering means that you have to do more work
earlier in the chain to change the channels dynamics not just the volume. eg bring the
output level of the synth down a few db.
Hope this clarifies a little. May have
got a bit lost.

another thing to watch out for -
very few plugs have metering (on the plug
itself) so although some might have a soft clip option, using the volume control on the
plug itself is prob best as opposed to the track fader.
(assuming of course
that you aren't deliberately overdriving the plug's input)
iow you could have
no clipping visible on logic's meters whatsoever but still having clipping within a plug.
