Cross fade between velocity switch

[paddyryan]

I've imported all my Seidzlak (wrong spelling) Advanced Orchestrsa library to Mach 5. Some of the programs had a velocity switch (eg. between p and f samples) that on my Akai S5000 gradually cross faded from one sample to other other as the velocity was increased. On Mach5 5, it just switches from one to the other at a certain velocity threshold.
There are many other programs too (some Mach5 bass programs, for example) that have a very obvious and abrupt switch from one velocity layer to the next at a cetain velocity threshold.
I can't find documentation on a way to have it blend gradually from one to the other. Can this be done?

I don't think velocity crossfade is supported in MachFive.
It's a feature I wish it had.
