Distorted signal recorded - SOLVED!!

I'm having a problem in Kingston Platinum with recording that I do not have in X2 Producer:
 
In Platinum Kingston, If I record a source onto a track, such as Track 1 and I arm and record on track 2 as well (even if there's nothing to record on Track 2), the playback of track 1 is slightly distorted. If I disarm Track 2 and record only on Track 1, it's clean. If I perform this same test in X2 Producer, there's no issues with audio quality.
 
I'm using a MOTU 24CoreI/0, Internal clock or BLA external clock. 96Khz or 48Khz, 24-Bit. I just update dto the latest Audio drivers from MOTU on my Windows 8.1 Machine.

I think there is a routing issue. Check all settings of the MOYU. If it has software be sure it isn't monitoring and sending audio to track 1 from the inputs of the MOTU. You will need to check everything. Also be sure there are no sends in Sonar active. A patch point maybe active. 

Yeah, checked routing, etc. As for patch-points, I'm not sure. I can only assume that there's no patch points from every odd-numbered track to ever even-numbered track in the template. All MOTU settings are perfectly matched to X2's test. No changes were made here. At first, I thought it might have been my clock, or my OP-AMP mods, but I've never had this issue in older Sonar versions, only Platinum under Windows 8.1. I don't have a Windows 7 or 10 machine to test this on.
 
If I only record the one track, say track 1, then there's no static/distortion. If I arm Track 2 as well, Track 1 during playback, Solo'd or not, will sound static-y or distorted. I can arm all other tracks except the Track # after my source audio track, and I get clean audio recorded. It's only the next track from the one I'm recording audio on that causes this problem (audibly). For example, I have a 24-track template. I arm Tracks 1, 3-24, and record bass guitar or vocal onto track 1. The playback of Track 1 is clean. If I arm track 2, and record (in other words, all Tracks 1-24), then Track 1's playback is audibly affected with static or distortion. Same thing with arming 1-3, 5-24 and recording onto Track 3. If Track 4 is not armed, then Track 3's playback is clean. If I arm all tracks, 1-24, then playback of Track 3 is audibly affected. I have not tested this on more tracks, but expect the same results. I also have not tested to see if Track 24 was clean, since there's no subsequent track to it.

Again, none of this happens in X2. I'm planning to try X3 this weekend. As of now, I will have to use X3 to Track with and move the projects over to Platinum for mixdown. I've not had previous issues with X3.
 

I left work early to Call Support, and they're not open today. :(

Try this for kicks - if you have "Remove DC Offset" set in preferences, uncheck it and try again. Honest! There is a crazy issue with that that occurs in Ipswich through Kingston, but not in X3 through Hopkinton. I have not written anything up or posted yet, as I just completed three days of troubleshooting this morning and my head is still spinning.

That was IT!  Solved!!  Thanks so much!!
