Alesis DM5, MIDI-USB and the no Note-Off Hell

Hello fellow MIDIers 
So, i guess the tittle pretty much sums it up. Let me explain what's been driving me NUTS for months now: i bought this second hand DM5 vdrum kit and planned to buy a midi-usb cable to control sample packs with it. After buying the cable and spending weeks figuring out what i was doing wrong, i discovered it was in fact a faulty cable.
Then i got borrowed one from a friend, which is the exact same one, but guess what! This one does manage to get notes.
Problem is: it's one of those cheapo VIEWCON cables, so i never know if it's something i'm doing wrong, or just a damn bad brand after all.
Here's my problem: all i can get are Note ON signals. And yes, i do know that the DM5 sends Note ON with 0 velocity as his way of saying "Note OFF", but that's not the problem here. Checking the inputs, all i get is ONE note on per pad hit, so i guess it's either not sending Note Off at all, or the little usb-midi thingy isn't capturing it. Hence, all i get are stuck notes.
Here's what i figured i'd do: for each and every NOTE ON event i captured, i would generate a Note OFF event with a small delay (after all, it's a drumkit, so it's no problem not having notes that i can hold). Problem is, the best i got was sending not offs to the OUTPUT monitor :lol:
this is driving me nuts so basically what i wanted to ask is:
can someone make The Complete Idiot's guide to generating NOTE OFF events from a NOTE ON and making them go through the same pipes (TM) (and not doing one on INPUT and one on OUTPUT)?
Thanks a lot to all who read this far and god bless the good soul that helps me!

Hey Peter! Thanks for your reply
I had read through that topic before and tried to figure out if it could help and i ended up in the "midiox would have to know the future" thing, so i figured it was a different problem.
Do you think that applies on my case too? Or is it just that midiox can't really generate midi notes from scratch and send them in the same input?
Because, i mean, it would just depend on past events (the note on that was just played), nothing else, right? Or am i missing something here?
but i most definately agree that the next time, in no way i'm buying generic MIDI stuff

Ah, sorry...
Well if you're getting the Note On you want and just want to add another even after a delay, then yes, no problem.
Set up a data mapping for "any" Note On event that passes through that event and maps to a Note Off event with pull through of the other details, delayed by however long you want.

Hey Peter!
Impressively even to me, i just had time to fiddle with this again now, after over a whole month
So, here's my problem atm: i create the midi mapping by generating a "note off" everytime a note on comes. And it works.
The problem is that the note off is in the OUTPUT channel, not the input channel!
So i figured i should create a note on AND a note off to the output, say, linking it to a MidiYoke channel, and then i'd have both signals being sent to a "MIDI IN". But aparently, only one mapping works at a time!
Can someone help me with that?
Here's a screenshot of what it looks like:

I don't understand why the Note On doesn't show on the output monitor...
You can't send to MIDI In. That's where input comes from. Output goes to MIDI Out.
(source MIDI Out) -cable-> (destination MIDI In)
That's the only scheme MIDI supports.
You need to set up like this:
(source MIDI Out) -> (PC MIDI In)-{MIDI OX}-(?? MIDI Out) -> (?? MIDI In)-{??} ...etc
