MIDI guitar with Helix in Helix Posted November 30, 2018 I wanted to revisit this thread. I have an HX Effects and I'm trying to figure out how to change patches in midi guitar 2 via the HX using an instant command (PC message) as described by amsdenj above. The HX effects is not an audio interface, so therefore I need to run a usb audio interface in the chain. So I plug my guitar into the HX, then use an effects block to send the signal to the USB interface, when then sends to my laptop running midi guitar. The usb interface connects to the laptop via usb. Ultimately what I want to be able to do is use this for live use, where I can change presets in the midi guitar standalone app or in a vst that midi guitar is hosting using the HX effects. Similar to what amsdenj described above. I'd like to determine if this is possible before I drop $100 and buy the software. If I can't use this live and change presets via the HX, then I really don't have a need for this software.
