No Mixer showing up in the Arranger tab - MIDI FX Logic

Hello,
The Mixer isn’t showing up in the arranger, as pictured.

Also, I don’t know if this is related, but the MIDI channels don’t seem to be routing to the external VST instruments in Logic.
The “Internal Midi In” only has an “Instrument Input” option, no outputs.

Welcome to the forum @micahtewers Is this because you have loaded Scaler 3 as a MIDI FX in Logic? It’s correct not to have a mixer as it can’t host, it only passes through to your Instrument. Load Scaler 3 as the instrument and you will see the mixer.
