Thanks to Micca, I've been able to revert back to my 5 (I think) year old Yamaha daugter board and and happy with my MIDI again.I thought others may be interested in the difference in sound between this and the two possible configurations of my new Sound Blaster Live card. This is a sort of middle of the road example - sometimes the differences are more striking than others.
The recordings in RM are not that brilliant but I have put them here together with the MIDI file I used.
