When I load seq, they sound different than how I made them

i got this problem on the mpc 1000 (black, OS version 2.0)..
lets say i load two diff sequences
both are made with the same kits.
however on one sequence the kick or snare will have a slightly different tone
sort of like a grimy tone.. like it lost quality.
Anyone know why this occurs and how to fix it?

theres many things it can be. u got either a short sample with a release set on it or its loopd small witch creates the jessiah glitch where it plays the sample but plays other samples with it. its weird to explain but it does create that grimy sound ur talkn about. this btw is a bug and needs to be sent to akai for the next version os, explain to them what u discover. but then agin its prolly nothign after all. if u can record this example for us maybe one of the guys here can help. me im nto sure what all is the problem really. i load same program to other sequences with ease and never notice a weird effect to my sampels when they play. they still sound the same. maybe ur not telling me somthin. could it be that u didnt save ur program? even if i took a program with my sounds and made changes to the filter or in effects in the mixer i still hear the same sound in the next sequence. no grime effect there. tell us more the problem in detail so we can recreate the issue so we can help u better

I made two sequences using the "samba set" or whatever its called..
but I made them on diff days. One day I loaded both.. and kick of one sequence sounds noticiably diff than the other sequence.. that's all

this btw is a bug and needs to be sent to akai for the next version os

isn't it already fixed in os 3.0?
