Disabling simultaneous notes from a MIDI Controller

[Grayburg]

Not sure how to say this, but I want it so that when I perhaps hold two keys, FL will play the first note, then when the second key is recognized, it will stopplaying the first note, and then play the second note alone.

edit: LOL JUST KIDDING. Just found out I was supposed to set the Polyphony to 1.

There's also a "mono" option in the misc tab of of the channel menu. There's a portamento option there too if you'd like to do slides from one note to the next.
