any way to get it work in Ableton?
Yea same deal as BandLab and Cubase.
Load PluginFlipFlop (FX or instrument) then load BBvst (FX or instrument) into it.
If the BiabVst don't stay on top use an Always On Top app like the one in the link Always On Top 1.3
Joao from JBridge is going to make it stay on top.
