Still focus is not important, echo is. Focus does not insure echo. It requires "Always Echo Current MIDI Track" and while this is the default not everyone has it enabled.
Good point. I have not changed that option for long time and forgot about it..
Having focus enable echo can mess with input settings. I have never crashed SONAR as a result of MIDI input settings although LoopBe will complain if I set up a loop. I can deal with that. I never use global omni either.
With external looping I also had no crashes. But when I used MIDI output from VSTi, many things went wrong periodically. In some situations Sonar "forget" the Input assignment, reverting it to global omni. When that happens, Sonar not indicating it visually (Input is still names correctly, till project reload). May be that was my setup specific, but I had it with several different VSTi, including my own. Since then I prefer to avoid MIDI VST and that was the reason to write Lua MFX...
