After a suggestion to route MIDI to my stage piano, which is awkward for me, I decided to buy myself a Ketron SD1000 and route the MIDI to that.

It seems to do a decent job, except that the volume of my piano was rather low in comparison with the mix of the BIAB Instruments.

I enabled 'Thru' on the mixer and increased the volume to 127, which made it reasonable, but felt like a bad solution.

I figured that the master volume controls were probably there for this purpose, so I shifted the volume control left. No effect. Everything just kept playing at the same volume. I muted master and the sound mutes as expected.

I started exploring further.

The individual tracks: volume, mute and solo, operate as I expect.

But those master volume controls do nothing.

I also now realise that the master VU meters show nothing, but that master mute still mutes.

Am I misunderstanding something?

Oh yes, Build 833.

Thanks.
Gordon.
