|Summary||0008386: Unexplainable MIDI note emphasis in General MIDI Synthesizer|
|Description||I've made a simple MIDI region and realized notes starting on the beat lines are sounding a bit different, and I don't know why.|
I've tested different octaves and MIDI channels (General MIDI instruments) - this is still audible.
1. Crete a 1-bar ling MIDI region with 1/16 Grid snapping on and the General MIDI Synth on.
2. Fill it with 16th notes.
3. Play it and tell me if all the notes sound the same.
Can anyone reproduce this?
You can verify with a-midi-monitor which events are sent to a synth.
GMSynth varies samples in a round-robin fashion. If there are 4 samples for a given note, it may well sound like a small rhythm when an identical note is played repeatedly.
(This avoids the machine gun effect).
I think it's not round robin, because it changes depending on the session tempo - and that shouldn't affect it. At the default 120 BPM each quarter note stands out, but with other tempos this is way different or even non-existent. It seems like an interplay between two repeating events, maybe it is some kind of timing error?
Shortening the notes didn't seem to make any difference in my case. Maybe the note release was just too long for that to make any effect.
