Midirocker LX as midi to USB with duration feature

[mmaru...@gmail.com]

I want to use midirocker LX as a general midi to usb adapter, for the 10-50ms duration function.
I want midi rocker to pass all midi information form my Alesis Controlpad, to my laptop, with the addition of note duration, as the only modification to the signal.

Alesis controlpad has a usb output which works great, but the note lengths are too short to be useful in some areas of my music software. they are less than 10ms
