Many, many, MANY moons ago I used to be the administrator of MidiWorld.
Les Winters, the originator, handed it over to me when he became very ill, went back to his home country and later, sadly died.
The problem became, with the forum, that the number of spammers that jumped aboard daily became too much to handle.
The MIDI conversations dwindled to almost nothing, so I closed the board but left the files in place.
Somewhere, goodness knows where now, I've got a complete backup of the site, and a login, which I seem to have mislaid. :-(
It all happened something like ten years ago and I've moved from Germany, where I lived for some years, back to England in the meantime.
How time slips away, and so, so many people I knew are no longer with us.
Ah, well!
It's what happens, I guess, when you get old.
Try changing the grid to 64th notes and show 64ths too. You'll see, maybe how it was done.
