Hi @helpful_community! I have been working for a while on two applications for two performance MIDI controllers. They have been working fine, both separate and in parallel. I have added further subpatches and configurations to them and now when I open one and then the other: Max crashes. I have opened previous backup versions of those paches and Max did not crash so it seems obvious that my recent additions will cause it, and it can be reduced to one of the two patches for only this one causes the crash… yet, I have no clue on how to troubleshoot or investigate the matter.

Does anybody have an angle on it or is there something I can provide to help solve this problem?

Thank you very much in advance. shgn
