Scaler control doesn't work on my midi fx, but works when I insert it in my instrument track

Logic x midi fx

Hi @littlefires when using Scaler as a MIDI FX you need to load an instrument on the same track. Once you have loaded your instrument, try to send a MIDI note from your MIDI controller or the Logic virtual keyboard (Window > Show Keyboard) to check if the instrument outputs any sound before clicking on Scaler
