I recently bought the Korg M1 vst to use in GarageBand. GarageBand will load it just fine. I can hear notes when I use my trackpad to click on the virtual M1 keyboard. But my MIDI keyboard won’t work to play the M1 sounds. Nor will it play the M1 sounds if I open the vst outside of GarageBand. The MIDI keyboard plays all the factory sounds in GarageBand just fine so I know it’s working ok. I have a 2012 Mac mini running Mojave. The keyboard is an Alesis Q61. Thanks for any help!
