Arpache SX & merge Midi Loop

I’d like to record the notes that Arpache SX is playing into a midi channel, but when I use Merge Midi Loop, I’m getting the original chords as well as the notes in the midi clip.I have Erase Destination checked but it makes no difference. Any tips?
Thanks Frances

Do you have “MIDI Thru” checkmarked in the Arpache window?

ahh thanks! solved!
