Hi Bob,
Now, I am getting even more confused! You mention exporting the file as a .wav file. This isn't the problem I have. The problem I have concerns the way that midi data input from the midi controller is processed from within BiaB.

The way I see it, and I may be completely wrong here, is that the midi from controller is passed in to BiaB via the Thru channel. This midi is passed to the selected BiaB channel and is converted to audio by the synth on the Thru channel.

So, when I record, what I am really recording is just midi which will be visible on the Piano Roll. Now all of this works correctly. With the Melody channel selected and I play the keys on the controller, then the sound generated by the keys is as expected by the sound defined by the synth on the Thru channel. Where I have a problem is that when I play the keys I get a low dB value from the synth, way below the levels on the other tracks. To address this I added a Dynamic plugin to the output of the synth on the Thru channel and then increasing the gain of this plugin. This work just fine.

However, having now used this output during a recording session and playing back the midi, I now get that reduced volume again. This is because the midi is now coming from the Melody track and through a synth on the melody track. So, I did the same here, I inserted a plugin and increased the plugin gain. But this time the output was not affected (I don't understand why). Anyway, just to try something out, I chhanged the Melody synth to the Sonar TTS-1 and this DID work. So I have the process working quite well. It's just that I thought there might have been an easier way to do. I mean, I would have expected the faders on the Thru and Melody channels to have sufficient volume range to meet this requirement.

In fact even RealBand suffers a bit like this where the midi generates a very quiet audio. RealBand gets around this by providing a 'Volume Boost' in the range -24dB to + 24dB which I have had to muse on many occasions. But no such mechanism seems to exist in BiaB.

I'm hoping somebody can point out that I'm doing it all wrong and tell me what I can do.
