Saga Musix 2017-07-24 11:37 administrator ~0003114	PortMidi is somewhat buggy so we switched to a new MIDI I/O library (RtMidi) for OpenMPT 1.27. Backporting all those changes to OpenMPT 1.26 is out of scope though, so you will have to obtain a current test build from https://builds.openmpt.org/builds/ for now. Those shouldn't crash anymore.
