Nevermind, I solved my own problem. I had to use a midi channel filter to set the samplers to that respective channel.

Update:
Using a midi channel filter set to channel one blocks all samplers from producing sound, implying they all output on channel one, which the midi channel setters should be fixing.

I am attempting to have different samplers played by different channels of midi input to avoid overlap when using a keyboard floating tile, however, the keyboard plays all channels at once despite all samplers having a midi channel setter and the keyboard itself being set to a midi channel in its data.
