![]() ![]() This is a well known C++ problem which is called the static initialization order fiasco. #Midi monitor error codeUndefined things happen, usually on ARM chips resulting in a memory fault which for all practical purpose means your code crashes. When your constructor tries to access an instance of another class, that instance may not actually "exist" yet. If they use virtual functions, their vtables may not yet be initialized. To understand why, in a nutshell when your object and other objects it uses are all created as global / static, the other objects you try to use within your constructor may not yet have had their constructors run. #Midi monitor error serialThe common solution is to create your own begin() function, and use it to call any other begin() functions for serial and other hardware.Īs a general rule, for classes that will be allocated as global / static, you need to restrict your actions in your constructor to only your own class. Usually you can't call serial begin() from your constructor, if your object is allocated global / static. When you post the complete code (or a small version, but still complete and confirmed to reproduce the problem), we can usually help. ![]() We have the "Forum Rule" for exact this reason. Their data just sat neglected in the other copy of the serial object they has unwittingly created.Ĭ++ syntax and semantics can be tricky like that. So their code within the C++ class was writing their data into a completely separate instance of the serial port, but of course the hardware interrupts were only servicing the original one. The net result was they has two completely different copies of the serial object. It turned out to be a simple mistunderstanding/mistake of using "static" within their C++ class. ![]() Writing to the serial port in loop() worked, but writing to it in their class didn't. This may be stating the overly obviously, but showing us a program that does work isn't going to enable any of us to help you figure out why your unseen C++ class code doesn't work.īut maybe it'll help if I mention a very similar question came up a month or two ago, involving a C++ class for a giant MIDI controller project, which abstracted the serial port. It may explain why the people have experienced this around the same time too, since probably everybody loves getting new freebies.My problem only arises when I try to move some of this functionality into a library, building a class to represent my hardware. That helped a bit, but I still get this from time to time. I had to trash a couple new free plugins on my computer because the trouble started immediately when I installed them. So to test it, I deleted the first region and replaced it at bar 1 with a copy of the duplicate I had put at bar 5 (even though they were identical) and it worked. #Midi monitor error fullThis can't be, since I've used this region in a full song with the EXS before. So I put one 4-bar region at bar one, and then again at bar 5, into an empty autoload and still got this error message repeatedly at exactly 3 measures into the region using the EXS. I also have been getting "Error while trying to sync audio and midi". I wasn't having this problem at all before, but strangely, when I did a search on it, many people are saying the same things have started happening to them all of a sudden too. No new drives, and I don't think they are set to sleep. ![]()
