Finally (for now!) there one important thing you can do if you are considering using audio backing tracks at some point in the future.

Be aware, there is NO WAY in the BK series to permanently adjust the volume or EQ of an audio file. The Mastering Tools EQ's and compressors ONLY work on the MIDI side of things.

So before you do a ton of work on styles and sequences, it helps to load up a few CD tracks of stuff you're completely satisfied with the balance and overall sound. It also helps to not use modern music or 'remastered' CD's that have had their dynamics crushed to death and are crazy loud.

But use those CD tracks as the volume and EQ balance reference for your system, then balance the styles and sequences to THAT by using the Mastering Tools EQ's and compressors to match as closely as you can.

By doing this, you won't be faced down the line with having to EQ and adjust all your audio files to match somewhat unbalanced style and SMF balance.

On the gig, you can use the Balance knob to reduce the volume of an audio track, but be aware, you can't increase its volume without increasing the Master Volume of the whole arranger. So I tend to shoot for a balance knob at about 2pm for audio files, in case I come across one that's just a little to quiet.

I like a fairly dynamic sound (live band feel) from my styles and sequences, so I tend to turn off the Mastering compression, and just use Mastering EQ (in small amounts) just to match the overall MIDI tone balance to the audio files.

Do this as early as you can in the process and you'll save yourself a ton of work down the line if you start to use pro audio backing tracks...

Hope these help.
