How about if I send a MIDI Command from my Helix via the H9 to the iPad?
Will that be a reliable connection? What do you think?
Well Helix is the same as H9, which doesn't support Bluetooth MIDI.
You'll need something like these to work with your Helix.
Got it. Is it possible to put any of these into the MIDI OUT of the H9? And which one is better, do you have any experience with those?
