You need to understand that the Organelle is a USB host so you’d typically need to go:
Laptop (with Ableton Live) → MIDI Output Device → (MIDI CABLE) → Midi Input Device → Organelle

With this you can go:
Laptop (with Ableton Live) → USB MIDI-USB → Organelle
I’ve not used it myself but by all accounts it works a treat.
