I’ve been programming some midis and for some reason when I have a back to back midi note, the midi notes drop out. For example when I have straight quarter or 8th notes lined up and quantized perfectly, it seems to drop some of those notes. It’s only when I select all of those notes, turn the snap off and ever so slightly roll back each note’s length to create separation between notes does it sound OK.
Take in mind this is for notes of the same pitch. The midi notes aren’t actually overlapping either.
