I have the same bose L1 and VoiceLive.

I just did the following:

1. Go into Opts Setup Output Channel.
2. Check the box for Vocalist.
3. Ensure that it says Midi 5.
Close box.
4. Open the Channels in Opts Prefs and ensure that Midi 5 is assigned to the soloist channel. I now don't use that channel, only to embed cc controls.
5. Close that.
6. Set your Midi Voice Controller to receive Ch 5, that should be all she wrote.

With my setup as soon as I press play the midi light begins to flash on my voicelive, and I can see the chords. Note if you have a chord dispay it may be relative, for example you expect to see a D chord but see a C# chord instead, this is normal as far as relatives being weird goes.

Later you can check through the patches in your book and charge harmonies. I usually have one that thickens my voice and start with that say, 3.6 so at the first bar of the song I press F5 and enter instrument 36 which is some kinda guitar. But if you watch it will change the harmony patch. At least for me. If later you want to have the song do it on autopilot that works too...
