If you use the helix usb out to connect to a computer or iOS device you can use an app called MIDI Guitar 2 that will convert your guitar into a polyphonic synthesizer. I get very nice organ , sax, flute, string patches this way.
It takes a while to figure out but, working in small bands it’s nice to be able to blend these instruments with my regular guitar tone.
i actually do this on a podgo, so it should be easier to set up on a full helix. Its even possible to do on a podexpress
