Hey,
I use 2 laptops on stage - one as hot standby. Songs, racks and setlists are synchronized via dropbox.
This worked flawlessly since months. Today I had a strange effect: after adding a song to my setlist I created some time ago this behaved differntly on both laptops.
After proofing it was really the exact same song on both laptops I found that every MIDI routing in this song seemed to be transposed by 1 octave on the second laptop compared to the same song on the first laptop (f.e. a routing with a keyrange from f3 to g4 is showing up as f4 to g5 on the other laptop).
Surprisingly this had no effect on nearly all routings means: even though everything is transposed (nearly) every routing produces exactly the same audio as on the other laptop when triggered from the same keyboard.
The reason why I’m observing an issue at all in this song is there was a suppress events filter in one routing allowing only three notes to pass. Here the note values are not transposed which easily explains the different behavior.
After changing this filter by one octave everything was fine again (but this would result in a differnt song for the second laptop).
I meanwhile could work around this for the moment by substituting the routing by some others not needing the filter anymore (for gods sake cantabile is extremly flexible as we all know ).
Next was to have a look at the other songs and guess what: the one octave shift is happening in all of them.
Even though I can live with the situation as is this is totally annoying and I have no clue what‘s going on here.
So any enlightment is warmly welcome,
Cheers, humphrey
