Static with USB audio on specific patch configurations

[nippyjun]

Hello,

I noticed very recently that with 2 patches I had purchased and installed if I play usb audio through the helix either from my mac or my ipad( with the camera connection kit) there is static.

 

I don't remember this with pre 2.0 firmware update but i'm not certain of this.

 

With any other patch; factory or purchased; this does not happen.

 

The static is not to my guitar tone but to the audio from my ipad or mac.

Both of these patches have a very similar aspect which seems to cause this.

 

This seems very strange as I thought that USB audio passes through the helix untouched by the patches themselves.

 

See the picture.

 

If I add any block to the right volume block in path 1a or left of the volume block in path 2b the static goes away.

It also goes away if I change either of those volume blocks to a different type of block (except send/return).

Also if I change the distortion to a different distortion it goes away.

 

Any thoughts.
