I have downloaded the trial version of the standalone app, but all I hear is the sound of my guitar. The test piano sound plays when I click on the virtual keyboard, but there seems to be no midi output coming from the guitar.
I am running a Macbook Pro running OS 10.14.4 with Focusrite Scarlett 18i20 audio interface. The interface is showing up in the MIDI Guitar GUI. Please can you advise.
