Weird sound issue on triggered samples

[Newcomer.band]

Hey guys! I am getting a weird flanger or phaser sound when I trigger multiple backing tracks for our live show.

I recorded everything in Logic then bounced down individual track stems to trigger in Ableton. The bass was recorded live using a direct input into the audio interface. The drums were all programmed in the box.

I've attached a link to the drums solo'd, the bass solo'd (ignore the pops), and the drums and bass together. They sound fine when they are solo'd but when triggered together I get a weird sound.

I don't get this issue during playback in Logic. Any help would be awesome. If you guys need more information let me know.
Thanks!
