[sdiy] What's a good velocity # for note loud vs soft?

Well... some synths of course can be mapped.  (Eg. Kurzweil stuff all 
the way back to K1000 series at least....save probably some of their 
consumer stuff.  )  Others have varied response I've seen to velocity 
even on the native keyboard (eg. the strange DK600 siel machine's 
response curves).. and many of course have less detailed curves to 
hard/soft selections.  

 Two velocities is a pretty terrible thing generally since it's going to 
inevitably give the player intermittent bizarre out of place louds at 
some point in their playing :-)  SO you might want to push up the point 
a bit so that you are having to make a very deliberate effort to trigger 
the loud.  I might go more like 5C to 6A for the switch point. -bob
