Hi,Mr.Dankirby,nice to hear your reply & thanks so much !
First link I've checked but nothing there,sigh
Geco midi can be download is a good thing left. but it's a pity my main tools is tekhtonic which can't be found anymore even it's website.
So It seems I can't have a tekhtonic installer alone like geckos installer and I feel bit sad again.
Anyway,thanks again for your kindly answer:)
Have a nice day!!!
Best regards from Taipei,Taiwan.
