OP-1 and Roland Boutique synth?

How can I connect the JX-03 to my OP-1? I’d like to use the OP-1 keyboards and sequencers to play the JX-03…

You need a USB Host. Your computer, your iPad, various iConnect devices, or the Kensington USB Host are viable options. Check this thread as well: https://www.operator-1.com/index.php?p=/discussion/1578/the-definitive-guide-to-trying-to-connect-your-op-1-via-usb-midi

I use either of the following for this very thing:

  • Kenton MIDI USB Host
  • Mac running Ligic Pro X
  • Mac running MIDI Patch Bay (free app)
