Alright, so this actually turned out to be a tricky issue...I tracked down the cause and it's related to legacy code in the Max SDK that I was using to calculate noise vectors. Normally banding like this isn't noticeable in flows where particles are scattered in 3D, but it does become quite noticeable when they're constrained to only 2 dimensions, like in your example...this is how the issue has gone unnoticed for so long (as far as I can tell it's existed since tyFlow's inception, due to me always relying on that legacy SDK code).
The fix is pretty simple...but has far-reaching implications (the fix changes the overall look of the noise to a degree, so it will affect all scenes that use noise in any capacity). Therefore, the fix I've added is going to be off by default ("legacy" mode will be on by default, to avoid breaking all prior setups). Users will be able to opt-into the fix by disabling the new "planar per-axis input (legacy)" checkbox available in all noise rollouts ("+/-" tab).
The new setting will be available in v1.027 (which is going live in a few minutes).
