Question : Logic pro X inconsistent with MSB and LSB codes


I'm using MSB, LSB and Program Change to setup instrument program on my external MIDI keyboard, it's a Yamaha Tyros 5. But the behaviour is really inconsistent. Some times it works, other not, and for certain specific codes, it never works.

I really have the rights codes (from official Yamaha Tyro voice list.

Example: I can't set my drum kit part to have BrushKit instrument with these codes:

MSB: 0 127

LSB: 32 0

Program Change: 89 (on yamaha list, it's 90 because they use standard 1-128 but Logic use 0-127)

So I'm sending these code, at the beginning of my track, but it never work.

Can someone help? (presently, I can't figure out if have have an issue with Logic Pro X (latest version) or my Yamaha Tyros 5 keyboard.

Here is an example it's working, sometimes: Have Bah Choir vibrato

MSB: 0 008

LSB: 042

Program Change: 39

Logic Pro X, macOS High Sierra (10.13)
