Please need Help!!! Random Tempo Issues

[ispeakstraightfacts]

I am making a beat with the Bpm set at 120 but playback sounds faster than 120 bpm. The bpm will randomly fluctuate either faster or slower during playback. I don’t have no tempo automation so I don’t know what’s going on. Additionally, I haven’t warped anything in simpler because I am only using one-shot drum samples in addition to Sylenth1, and Synthmaster plug-ins. Do anyone know what may be causing this?

Note: my ableton sample rate and audio interface are both set at 44100

Computer: 2017 IMac quad core 4.2ghz, 40gb Ram, and 1 TB of SSD , CPU never goes over 10%

Midi Keyboard: Akai MPK249 professional

Speakers: pair of Yamaha HS8


Interface: Apollo Twin Duo with thunderbolt connection

Unless Live is slaved to external clock it's very unlikely to happen.
Do you feel like it's fluctuating, or can you objectively observe it?
It's easy to get tricked by the way we play for example.

No, I don’t have any external clock. I am using just my Imac Apollo Twin interface, and Akai 249 keyboard to make beats. I can hear it speed up or slow down and back to normal again. I googled my problem and I found that someone has already had the same problem some years ago in this Forum and he couldn’t find a solution so I know am not the only one! I need help so bad cause I love ableton!
