Disabling auto rest on midi output

I use 0.9.4 Windows. When I export to midi using file - save a copy, I get a midi file with small rests appended between notes that have no rest in the score.

For example, suppose I have a C for 1/4 beat followed by D for 1/4 beat, in the midi file it becomes a C for 3/16 beat, followed by 1/16 rest, and then followed by D for 1/4 beat.

I need the midi output from MuseScore as an input for a voice sequencing program, so the automatic rests are undesired in this case. Is there any way to disable it?

Thanks
