I recently bought a used op-1 and I am having issues with the internal mic levels recording at very low volumes. I remember running some tests when I first purchased the unit (in a previous OS, unfortunately I didn’t write down what OS) and the Function Test had different tests for the microphone, line in etc included as well. When I go to do a test in the newest 242 firmware it only has 9 tests and then restarts. Anyone still seeing some of the other tests in 242 that were previously there. Currently it only does button and knob tests and plug in to usb for a power switch test. Seems very odd that all the other tests seem to be missing…
