Sergio, I have Amplitube 4 and it does indeed work with ASIO. The problem you are having may be due to the fact that Amplitube 4 is 64 bit. You will have to try it with the Jbridge wrapper if you want to use it in BiaB or RB.

Just another reason IMHO for BiaB and RB to go 64 bit.

Ps - I don't know if the above will work as I do almost all of my work in 64 bit. I use BiaB as a chord and/or lead scratch pad them immediately move everything over to my 64 bit Sonar.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
