Hi ED

Hmmm well that was a good report but not good news.
I do seem to remember having similar problems in the past with Yamaha keyboards both my DGX620 and my CVP405 but I was using Cubase and Sonar at the time.

It’s as if when the Yamaha starts to send midi data it sends a bunched up chunk at start of recording as it usually the first notes sent that seemed to stick.
One thing that can cause problems if both midi in and midi out are sent to the DAW.
is note echo and double notes if local is on at the keyboard as each note gets sent to the software via midi and the keyboard which then echo it back to the software.
One way to do this if using midi leads is to not connect them both that is only send nidi from the keyboard to the pc while recording
Or turn local off at the keyboards midi screen function / midi, /all parts / edit
When I tried this the moment I started to record in BIAB IT SWITCHED ON AGAIN
So I had to flip it of after the recording was running watch the Yamaha screen!!


Sona turns local of by default these days, but BIAB does not.

I usually leave at least one or two blank bars at the start of a recording to give time for all the initial track / channel instrument data to be written also you could try sending a single note first before, the what is often a large handful at the beginning of the track this is likely to be at least LH chord of three notes + RH notes that’s quite a bunch to write if it is still sending track data headers to the other tracks.

Pitch wheel and sus peddle mod wheel event should not cause a problem as the software will put them in an empty time tick between the notes , as all midi is sequential any way, only one thing can be written for any one time but with the sort of clock speeds we are talking about there should be plenty of room in one second for many events.
Good luck let us know how you get on
Mike
