I get pops/clicks in to the sound (audio) when I record. Also playback has
this problem. I think that midi causes this problem. If I mute all
miditracks everything works fine, but if I use miditracks I get those
pops/clicks. For midi there is Midiman Midisport 4x4 USB and for audio
M-Audio Delta 44. What may cause this kind of problem.

Thanx in advance (sorry about my english)
