Midi Feedback problem

[b1gkris]

Whattup Yall?
The problem im having is when i play back a track that ive put together i can here feedback from the keys that i played. for example if i play a loop ascending a scale from A to G, on each note i will hear some sort of click/pop sound in the background as if it is feed back from me playing the keys too hard. however i do not believe this is the case because i dont play the keys hard. i even upgraded from basic keyboard to an mpk24 thinking this would help. but it diddnt. the feedback can really only be heard if i put headphones in and listen closely but it is noticeable. Does anyone know what the problem may be?
Thanks.
I am using Fl studio by the way.
