It seems like I am hearing realdrums as sugested (the names ar written in green)
The other tracks - in this case bass and piano are written i yellow.
Maby I should try to change the driver.
It sounds like my suspicion was correct - you are hearing real drums and real instruments (which are audio), but NOT hearing midi. I'm on a Mac, so may only be of limited ability to help. Check out this PG Music BIAB Windoze tutorial on midi setup:
https://www.pgmusic.com/tutorial_bbw_nosound.htmYou've got to tell BIAB what synth you want it to use to play midi. I assume this will be a software synth and not an external hardware synthesizer in your case. Windows probably has some default midi synth (which likely sounds terrible). BIAB for Windows probably comes with some alternative software synthesizer you can install, which will be a big step up from the default synth in Windows. Good luck with this. If you can't get this going, just ask back here or contact PG support. You can use the program without midi if you just use all Real Styles, but it'll expand your horizons exponentially if you get your midi setup, and can then use ALL the styles.
