Ok, so a little over 1ms plus a little slop per scan.

At 1ms scan time I can't play fast/hard enough to reach the maximum  
velocity value so I may go with that for now, with the option of  
going up to double that rate.

I know there are a few people on the list who have designed and built  
their own scanned digital keyboards, so I'm hoping for some differing  
opinions.

Cheers,
Neil
