HA!!! Worked like a charm. I set up a user template with metro assigned to channel 16. I then used my keyboards Editor Software to set up a user template that has the patch "Castanets" assigned to channel 16 (which works very well for a click patch by the way).

I then maxed the volume of channel 16 and BAM! Instant click baby If I do end up needing track 16..., I can just make adjustments accordingly as I'll always have the user template for my starter.

Thanks for your replies guys. I was hoping I could just get the PC speakers to work, but it's just becoming a pain in the backside.
