I,ve been using BIAB since version 3 and ought not to need to ask such a simple question - I would appreciate help please.
My system Intel Core i5 8GB RAM Windows 7 Yamaha NP-V80 keyboard used as controller only. Pianissimo piano sound module. BIAB 2012
I do not use MIDI. I basically use BIAB to give me a first class backing band to my piano.
I set up BIAB to use MME drivers with MIDI out set to Midi Mapper or GS Wavetable synth and all plays fine.
I then open Pianissimo set to Realtek HD and ASIO4All V2 as ASIO device.
Pianissimo plays beautifully. Go back to BIAB and no sounds - I get an error message
"Couldn't open the wave device. The likely cause is that another program is using the audio playback or has left the drivers open"
Can anyone help please?
