Dropped out of Observe to address 1009 hz violins

Terra noticed that one of the 1000 hz violins was pretty high. Because LLO is down, we decided to quickly try to address it. At 17:29, I ramped off the gain for the 4.7khz mode for ETMY mode 10, switch the BP filter to FM1 for the 1009.44 hz mode and left the 100db filter on. While watching the filter output and a live spectra, I slowly worked the gain up, it's sitting at 100 right now and both 1009hz modes seem to be coming down. We'll watch for a little while longer, then move back into Observe.
