Ahhh I see, cheers Lethal..
See it's a sound I've made in massive, and I love the sound but obviously I can't use it via the synth though Reason without Rewiring it to Cubase or something. Which is a bit of a shame as I love the modulation capabilities of Massive

On the looping front, I've got an LFO heavily modulating the cutoff filter, so when it reaches the end of the sound I've saved it comes to an abrupt and out-of-time stop.. Which is a bit of a shitter, but it's such a good LFO

if you got an LFO on the filter it might actually mask the loop if the loop is a bit sketchy.
i cant remember what looping features the nn-xt has, and obviously the nature of the sound you have comes into play
but if you made the sound in massive the best thing to do is retake the sample but make it alot longer... I normally make a bass sound around 8 bars long just to be sure
