Custom sampler m4L patch works smoothly in max editor but clicks only when triggered in ableton

Hey guys

I cannot wrap my head around this. i have made a sampler patch that scrubs through a sample. it works without any clicks as a standalone patch not opened in ableton. plays without any clicks. but as soon as i trigger it inside ableton i start hearing these really annoying clicks when i scrub through the patch. Im using a switch ramp technique to declick my sampler could it be related to that ?
