I am not having this problem.
I have all kinds of data on all sorts of tracks at 1.1.0 and do not have midi notes dropping out.
I’ve got a Pyramid MK1 and haven’t seen this on any version of the OS.
However, I do have an evolving program change issue. Originally the program changes would upset the notes, and I talked it over with @squarpadmin via email and in an update the notes stopped getting cut out, but the program changes started to take a cycle to kick in.
I walked this over more with Squarp via email and eventually the problem seemed to go away. I figured they worked it out.
In the most recent rounds of changes (from 2.3 - the current beta) the program change delay/note dropping out issues have returned.
I wonder if you have program changes on 1.1.0 in your patterns/tracks?
If you do, try removing them as an experiment and see if that brings your notes back on the 1?
This could be a data hierarchy issue which can be solved, and has been solved before, but is easily overlooked because not all gear responds to program changes the same way (ex: The Access Virus just can’t do it on the 1, the Roland Boutiques glitch on the 1, and the OB-6 works like a charm no matter when you sent it.)
