out of nowhere the gremlins came out. Scoped out the auxs/cues and i see and hear an 11.25kz weeeeeee almost like digital giberish or a mouse getting strangled on the aux/cue master sends although its oscillating at much much higher levels, dropped all the dls not outboard gear, pulled all the modules and killed all the buckets all clean there as well, program out is clean, aux/cues direct out at patch is where ive narrowed it down to ....recapped the aux/ cue cards in center section noise is still there, im lost and its late , if anyone has any ideas or experienced this let me know. Thanks
