who is able to add random velocity in SEQ?

[bosone]

while thorsten is working on the new FM synth, i was thinking about studing part of the SEQ MIOS code to be able to add a randomization function to the velocity track.

My aim would be this one: to add a random value (fixed between a maximum and a minum, lets' say +15 / -15, however fixed in the code somwhere) to all the velocity tracks while they are playing, either in pattern mode or in song mode. the only limit is that velocity should not go over 127 or below zero.

would this be a very difficult task?

is there someone who has a basic knowledge of MIOS who can help me (ex. where to find the vel values, how to generate a random number, add it to the velocity value..) or, even better ^_^, provide this customisation?
