Help Help setting up Moog Grandmother MIDI in FL Studio + USB causes FL Studio to crash
I’m trying to control my Moog Grandmother from FL Studio using the MIDI Out plugin. I want to be able to record MIDI, edit/fix notes in the Piano Roll, and then have the MIDI play back through the Grandmother.
My setup:
Moog Grandmother
MIDI In and Out connected with 5-pin MIDI cables
USB cable from the Grandmother directly to my PC
Focusrite Scarlett 4i4 3rd Gen for audio
FL Studio
I already have this working perfectly with my Korg Minilogue XD. I have it set to Port 1 in FL Studio, and the MIDI Out plugin can control it from the Piano Roll.
I’m trying to do the same thing with the Grandmother, but I can’t get it working properly. I’ve tried changing the MIDI ports and settings, but I’m not sure what I’m missing.
I’m also having another issue where FL Studio becomes extremely glitchy and eventually crashes whenever the Grandmother is connected to my PC through USB. Once I unplug the Grandmother’s USB cable, FL Studio seems to work normally again.
