Can music that is saved on Sibelius 3 Using Virtual Drumline 1 Templates be used with Viirtual Drumline 2 ?

Sure! This is why there are VDL1 versions of the VDL2 sounds. Simply open your older VDL1 score, and route its midi to VDL2 as you would any other VDL2 score. Then in VDL2, load the VDL1 versions of snare/tenor/bass/cymbal to ensure your score plays back to these instruments which use the older VDL1 mapping.

Thanks Jim, then this week I'll order Virtual drumline 2
Bye the way I'm a big fan of your arrangement when you were with S.C.V
thanks again. rob
