MIDI Channel Picker:
By @xorome


A JSFX from our very own AS fellow member, @xorome. It was one of those "ask and you shall receive" moments. I was looking for a plugin which could route MIDI signal to a selected channel, so i made a post here, and dude stepped in and was kind enough to share his skills for free, and made me the script. You can read the complete process in here, just wonderful.
Original Thread:

Here is his post with the final result,
