to do that...
1) go to the menu bar(the bar near the tempo)...then go to channels....
2) Once there, go to "Add One".... you should see a window that shows you all the vsts and other channels that are currently registered to your fruity loops... among those options should be a channel called "REWIRED"....click that so it opens into a channel
3) Click the channel "rewired"....once the window opens.... go to where it says client... and it should say none..... change that.... make it say "Reason". After that, click "SHOW PANEL"
4) The reason program should open up........get all the shit that you want open to start off... you know... the mixer, subtractor, maelstrom, etc.... then minimize the window for now.
5) Go back to the Rewired channel.....and click where it says Midi Options...
6) This should bring up yet another window, containing two columns entitled "Mappings" and "Channels".... click anyone of the channels...it doesen't really matter which and click "Add/Change" Towards the bottom left of the window
7) Once you've done that, go back to the place were it says channels on the MENU BAR.....where you intially started.....and go to "add one"..... open up the channel called "MIDI OUT"....
8) Click the channel...and in the window that it opens.... click and drag your mouse over the "Channel" slot in the top left of the window...disregard the port slot as it doesen't really matter...
9) As you go up and down through that channel slot, then it should go up and down numerically.... these numbers correspond w/ the numbers of the inputs in the rewired window....
10) So you will notice that now all your channels are routed to fruity loops.... all you have to do to play a channels simoultaneously in fruity loops is to open sepereate midi outs and assign them to different channels
Hope this helped....
