Looping complex waveforms

Iv never really been big into using multisamples of synths. However, Iv recently had the chance to sample some gear and I have a protocol down for sampling and editing. Looping however Im still unsure about.
I have Seamless Looper but didnt manage to get especially good results from it. My best results (when trying to complex waveforms like strings, unison synths etc) were achieved by manually performing crossfade edits in Cubase.
Im thinking about breaking the stereo files into mono's and trying Seamless Looper again. Maybe it will work a bit better this time (its an old version btw, I dont use it much).
So Im wondering if what people are using for this kind of task these days? Do we have any effective options outside of manual tinkering?
Cheers,

Mate, that is so kind and I REALLY appreciate the offer.
As it happens though, this is likely to be an on going project, so I could really do with finding a solution myself. I am able to loop these sounds pretty well manually. Its just takes a while, lol.
But seriously, thanks for the offer

Sound Forge has a feature called "crossfade loop" which I've used on many complex sounds
You can mimic the function by hand by doing this:
1. select a few bars of sound before your loop start point
2. Copy the selected part to another buffer
3. fade in the sound as you like
4. go back to the first sound, select from loop start to loop end
5. apply fade out on selected part
6. paste the faded in buffer sample on top of the faded out loop
7. enjoy
I can honestly say it's much easier doing this with the SF command than by hand. With a bit of practice you learn were to put start/end points so the faded in/out part doesn't sound strange but natural. Also, if you hear flange effects when the two sound switch you know you are almost sample correct.

Well, i do not like Crossfade Looping because the volume sometimes will be changed dramatically, when you start looping Sounds, try to program the Sounds without any Modulations like Panning, Pitch etc. when you only Sample the sounds itseld it's easier to find looping points..!

Antares still sells their Infinity looping software; $292, OS9 only.

It would be nice if someone would follow this up, it was supposed to be pretty slick.

Thanks for all the suggestions guys.
Yeah, Iv played around with crossfade looping in audio editors. Hmmm, I never got very good results to be honest.
However, Iv been performing the technique manually in Cubase with much better results. I import all the multisamples, then copy and overlap them all, click up a cross fade (set to equal power, solves the volume issue). Then I move the fade around until its no longer audiable.
The way I have it working now is pretty quick and easy. Its just that on some sounds I get this nasty 'flanging' over the crossfade. No idea how to deal with this. Im pretty sure its caused by phasing within the sample itself. Im thinking I might have to split the stereo file and see if Seamless will find a suitable loop for each seperately.

Are these for sustained tones?
Because tuning comes into the equation and you need to find the corrrect cycles and full integer ones at that to get seamless tuned sustained loops.

These are tuned sustained loops yes.
The ones Iv been having problems with are these dense unison patches which seem to have no 'perfect' loop points. For these Iv been doing the old crossfade.
But I should also mention that the loops are fairly long, way longer than just a few cycles. 3, sometimes 4 seconds.
The results Iv got have been alright. Just always on the hunt for more efficient ways to work, you know?
