Oh, and by the way; I have another USB MIDI interface (M-Audio Uno) which I connected.
Same story, same latency.
Which sound do you think lags behind the other?
1:
Does the MIDI output play ahead of the RealTracks, or does the MIDI output lag behind the RealTracks?
2:
Does this happen with Playback of MIDI, or with live input playing along on your keyboard, or both?
3:
Presumably you are using the Keyboard to play MIDI through the Ketron SD2. If so, is there a delay between pressing the note and hearing the sound, separate to anything BiaB is doing, or even if BiaB is not running?
Hi Trev,
The the MIDI notes are playing BEFORE the Real Insts. But not in all cases ... some lag behind and some are okay.
When I play my keyboard, the notes play in time, they are not latent at all.
I didn't realise that you & Mario are/were having difficulties with the program. I'm sorry to hear that. I can only think that if tech savvy guys like you are having difficulties fixing problems, there's no hope for a dummy like me.

I'll put your tests on the backburner for a while, as I have some interesting news.
I loaded BB2021 onto my Win 7 Laptop, and guess what? Out of the 20 or so songs I tested, that had MIDI Soloist and/or melody included, almost all of them played back perfectly. I made no changes to settings or to hardware. I'll try some more tomorrow before I get too excited.
So I can make the following conclusions: (for my setup)
BB2021 has latency problems with my Win 10 computer
BB2021 has fewer problems with my Win 7 Computer (only a few so far)
BB2019 & BB2020 worked fine on Win 10 computer
All of my hardware appears to be working correctly
Without jumping to conclusions, (and with the problems that you & Mario had) could there be issues between BB2021 & Windows 10? Although I'm sure the PGM staff & the Beta testers used the program on Win 10 computers.
Or are different settings in BIAB21 required for Win10 as they were for Win 7?
It's a puzzle ......
