High frequency distortion/delay

[RFUSED33874]

I'm just trying to mix, not record anything on top of what i've got, but on the ride cymbal i hear this weird lengthened distortion where it holds out the note and sounds digitized. When i solo the tracks it doesn't do it. Is there some kind of setting i can change? its about 34 tracks with only 2 reverbs run as aux inputs and some compressor plugs on some of the channels.

thanks,
Tyler

I don't know what it could be, but I'd solo the track then add in other tracks one by one (as in solo them together) to see if there are two tracks that simply won't work together.
