Okay, it looks like the bass track has an embedded patch change at bar 29, which is why you are getting the electric bass.

So do this to fix it (it's a number of steps, but will take all of a few seconds to accomplish):

1. From the top line menu, select "Edit, Copy Special, Copy/Move Tracks".

2. Since your soloist track is empty, this should work without affecting the rest of your song. Select the Bass track as the source track and the soloist track as the destination track. You should be able to leave all channels selected.

3. Leave "Merge with existing data on track" unchecked. Click on "OK - Do it".

4. Click the Play button, but you can stop after the initial count-in. Just need to make sure everything is on the Soloist track. The Soloist track will have the wrong patch setting. So, just right click on the "Soloist" track radio button (it's the one between the one labeled "Piano" and "Thru"), then from the popup menu, select "MIDI Instrument Patch", then select "Select General MIDI Patch". From the list, choose the Acoustic bass patch you want (probably 33 - Acoustic String Bass). Click on OK and then you will get a "Question" box that says: "Soloist has embedded patches in the track, example: Fretless Elec. Bass at bar #29. OK to remove all these patches?". Select "YES".

5. Now right click on the Bass track radio button and select "Track Settings, Unfreeze Bass 1 Track".

6. Now select, "Edit, Copy Special, Copy/Move Tracks" again. But this time, select the soloist track as the source and the bass track as the destination.

7. This will copy over the soloist track to the bass track and refreeze it.

8. Now select "Soloist, Edit Soloist Track, Form, Kill Entire Soloist Part". Then click "Yes" when asked to erase MIDI data.

9. Save your file (new name if you wish).

Your bass track should now only play the acoustic bass patch.

Don't know why there is an embedded patch change, but this should fix it for you.
