ok: Ill play Some kick samples in media player and hear one that sounds spot on, then load it into halion, when I play back it doesnt sound the same..seems to loose defintions..making an ace kick ok..same if I load it into cubase as audio and play it..surely things shouldnt sound crapper in cubase..?

You're not the only one. I've noticed that Halion often crappifies percussion samples. Make sure that the amp filter release is fully open so that it isn't cutting the samples short and that the filter is on LP and completely off. Otherwise, I don't know what the deal is with Halion.

thanks dude, Ive actually played back with the filters and envelopes all set to bypass,still weakens the sound, If thats halion itself then its basically crap

what sampler are you using ourself mate, and does it keep the sounds the same as when they are played in media player, i.e a good sound stays good rather than crumbling like a cake..
