Noises (clips) with voices recorded in live mode

Hello.

I have my AK with OS 1.24C.

I have very unpleasant noises when I record in Live Mode, overdubbing voices (Large duration)

For example:
TRK1: Bass drum 1 trig per bar
TRK2: Pad 1 with two voices recorded in live mode changing every 4 bars (large notes)
TRK3: Pad 2 With 1 voice recorded in live mode changing every 4 bars (large notes)

The kit is set in 4 voices polyphony.

After record the track 3 start to appear some noises (like clips) very unpleasant. Is impossible work with that. I have wasted a lot of time trying to fix it (with synthesis and parameters) and Im finally thinking that its an internal problem related with the sequencers or the new OS because if I play without record this noises does not appear.

Any suggest will be very appreciated,

Regards.
