I've been dealing with this since I got Logic Pro, but a new Logitech MX Master 3S mouse (with DPI control) seems to have eliminated hardware as the cause of it. I'm writing to ask if my understanding of this problem is correct, and what, if anything, may be done about it.
When I try to set and adjust an automation point for Gain, Volume. etc., I cannot get a continuous series of values in 0.1db increments, and I can (almost never) go straight to the value I want. It's not that it can't/doesn't happen, but it typically takes at least 3 attempts, and oftentimes more, from each direction, to get a series of numbers that includes the value I need. And that's taking far more time than it would if it worked as needed the first time.
The number series that's provided varies each time I release the point and start again, and looks exactly like I've been dealt a poker hand with a random/variable sequence of values. Past experience suggests the resolution of that sequence depends on the zoom setting of the track, where larger provides more choices, but fully zooming the track will not solve the problem.
I'm working on a project that requires a lot of adjustments to individual tracks to correct problems in the gain structure due to the way it was recorded live. Doing that works well in 1.5db increments, and those make it easy to accurately adjust tracks that need to be edited later.
Please let me know if I'm missing something here that could provide the resolution I need.
