I'm unaware of any suggestions identical to this one, though I have seen similar (most of the others were related to humanization). I feel the inclusion of a velocity system would really kick the programs flexibility and usefulness into overdrive. By this I mean a system whereby the user can right click on any individual hit and alter it's velocity between 0-100 and this selection be preserved when exported (so for example the velocity recorded in the MIDI track after exporting). This would enable the creation of subtle snare rolls and dynamic variation not possible at present.

Is this a feature that may be included in later versions?

Thanks
