something adding extra midi notes

Hi all,


I've seen various forms of this issue before, and have tried each of the solutions, but with no luck so far.


I'm using Logic Pro X (10.4.1) on a 2017 MacBook Pro (High Sierra 10.13.6), with an old Ensoniq SQ2 keyboard using MIDI-to-USB input. Logic is reading the midi signal, which lets me play and record, but something in the chain adds extra MIDI notes any time I play more than one note at once on the keyboard (hold a C and a G, Logic adds an extra G when I release the keys.) This makes slurring notes impossible without Logic adding extra unwanted MIDI notes, and is getting really frustrating- any thoughts?
