cherub 0 Posted September 6, 2018 I'm on the cusp of investing in a Helix HX, and part of the attraction is being able to control my amp channels & fx loop with it. I have an EVH 5150iii 50w head and currently change the channels with a Tech 21 Midi Moose using the EVH 'midi learn' function. I plan to use the same with the Helix HX. However, to switch fx loop on/off in the EVH, the manual states: "simply send a control change #85 message with a value of 63 or less to bypass the effects loop, or a value of 64 or greater to enable the effects loop". Can I do this from the Helix HX? Quote Share this post Link to post Share on other sites
phil_m 4,520 Posted September 6, 2018 Yes. It's very easy to do that in the Command Center. You could turn the amp's effects loop on and off per preset and/or per snapshot. Quote Share this post Link to post Share on other sites

soundog 491 Posted September 6, 2018 Also good to know the HX can send/receive MIDI through either the USB port its MIDI connectors, so you can use old-school or new-school controllers with it. Now that's flexible. Quote Share this post Link to post Share on other sites

Now that's flexible. Word of caution... standard MIDI (DIN) is self contained and works from device to device while USB midi requires a host. USB MIDI is great with computers, but generally speaking you cannot go from device to device with USB midi as it needs a host device (often a computer) to manage the signals. I suspect in the future there will be more devices that can double as a USB Midi host... but at this point the options are very limited, relatively expensive and/or experimental.

soundog 491 Posted September 9, 2018 If you get stuck in a situation where you need a host for a USB controller, but don't want to use a computer, get one of these: http://www.hobbytronics.co.uk/usb-midi-converter. They work great and are affordable. 1 Quote Share this post Link to post Share on other sites
