I use Geist to audition and bounce sampled loops into logic at the right tempo and it generally does a top job. I've recently bought a couple of sample packs from F9 - they are top quality but geist just doesn't slice any of the samples correctly. Even a simple 4/4 kick drum only loop - it will place the kicks all over the place. Ive tried renaming the loops - dropping them into logic resaving etc. Just wondering what it is about these particular samples that is throwing geist and looking to save a bit of work!
