Sample gets muted

I have recently encountered something of a problem. Sometimes when I lay down the sample in larger chops, like a four bar loop and then add drums after suddenly it's like the sample gets muted. In that way when you set the program polyphony to mono. Any idea why this happens?
The sample and drums are in different programs so I haven't accidentally done the mute pad thingy. And when it happened it didn't happen to the same pads, if anyone should suggest broken pads.

thanks for any help in this matter!

I think it's a polyphony thing...

try looking into that thread.

yup, classic polyphony mismanagement - covered on the forums. you'll find the answer.

thank you..

Feeling slightly stupid for not searching this up, but in my defence, I never would have come up with such a term as polyphony mismanagement

I tried to change the pads that I found was muting my main sample, and then it stopped getting cut off. But I figure this polyphony thingy is right because when I changed the pads I didn't make the same amount of layers, and that will have had an influence on the polyphony.. right?

since I've allready started this thread I thought I should ask about another problem that's been bothering me. Lately it seems that sometimes when I use the 'save all' function when saving a beat, some samples doesn't load when I load the beat again. They are in the folder allright, but they wont load with the rest of the beat and programs. So I have to manually load everyone of them. Not the biggest of problems, but still slightly annoying

Load the project file, not the folder

nah.. that's not it.. allready loading the project file..

This was happening to me also and I just started saving the program files individually while I still used the save all feature for the sequence files
