Checked out that Kemper on line, nice bit of kit. I have to admit, you have my VST monkeys raging with all this Helix talk. Please don't tell me I need that, I've been off of the VST for sometime now, except for that 57 Fender from UAD... But what harm is a little 15 day demo, no? Haven't got any external units like that, but after I got the VST thing under control, I had a guitar pedal breakdown though and going to try that hookup with them to see what you're on about with the hass. I don't think I tried that in pod farm.
