Thank you very much for your help. I downloaded the french version of Steem 1.5b. I'm going to try it. I hope that it'll answer to my demand. I'll tell you (this weekend) whether steem emulates correctly midi port or not.
Just one question : I read in the Steem web page that you send me, that Steem emulates midi out with parallel port, how can I use Steem midi out abilities if I can't use my PC midi port because Steem use parallel port ? Or, maybe I've not understood ??
