I have now tried the following:-

1. Reset to factory defaults:- this hasn't helped the situation (I did both factory default options - midi and non)

2. Started a new song and used the Bowey3 style as the "base" style, changing to the _COLDRO a few bars in:- this resulted in the Bowey3 style playing just the drums and when the style change came in all instruments started up (with the _COLDR style).


Aaaaaagggghhh . . . it's driving me mad.

Any other ideas/suggestions?
